Hello, and thank you for purchasing Solaris V5. Many hours of thought and work lay behind the design of Solaris. It represents the culmination of all my synthesizer development work up to this point; I hope it takes you on an enjoyable musical journey!

-John Bowen

What’s new in V5?

With over 110 new parameters added, obviously the old preset lists are not going to be fully compatible upon loading, but they should still play with no problem. I’ve taken the task of re-saving the factory preset banks to store the added parameters, which comes with the upgrade. All this means is, for your own set of presets, if you enable any of the new sections, their parameters will not be ‘known’ by the old presets, so that when you select an older preset, those new sections will remain active at whatever settings you last used them. Resaving over your old presets will take care of this.

Major new features:

Independent glide per oscillator

Added tables for Mod Wheel and Aftertouch

3 new ModChain modulation mixers

4 new xMult self-multiply sections

2 additional fi lter types, Mini and SSM

4 Key Level control sources

FX for pre-/post-fi lter, including Bitcrush, Decimator, etc.

Revised VCA output page in Mixer, allowing independent VCA control for each fi lter

Additional modulation for rate and depth added to

Vibrato LFO

Separate Noise sources added to Mixer inputs; new

Filtered Noise with variable fi lter type

MIDI timing added for all Envelopes

2 additional External Inputs


Installation is similar to that of other Sonic Core plugins.

Please note the following:


Unzip the fi le and drag the App folder into your SFP/Scope main folder. If asked to overwrite the folder, say ‘Yes’.”


Put the synth .dev fi le in the following location: SFP/



Put the Solaris v5_0.pre and other included preset lists in the location that matches your SFP Settings/

Directories listing for Presets. It should be something like SFP/Presets/Synths/ or just SFP/Presets.


If you have XTC Mode installed, and are using

Cubase or other Steinberg product, put the .dll in the following location: Program Files/Steinberg/Vstplugins/XTC/ (Similar paths will be appropriate for other VST applications.)


If you don’t already have it, you should install the font ‘Arial Narrow’ (Arialn.ttf) in your Fonts Folder

(otherwise, the menus and some other text will not look as I intended).


Restart or start up SFP/Scope


Select the Solaris from the drop-down Synths menu to load


You should get a message asking for the authorization key. Please copy the transfer string from that popup window and send it to me. I will then use it to process your key, and send it back to you.


Insert your activation key in your SFP Key fi le and backup this fi le in a safe place.


Once you receive your fi rst key, load the synth and select Mini or SSM in an activated fi lter section


You should get a second message asking for the authorization key. The process is the same

You must be using SFP v3.1c or higher to correctly run Solaris.


Solaris Synthesizer

The Solaris architecture is based on subtractive synthesis, which begins with waveforms rich in harmonic

(or inharmonic, in the case of noise) content that are progressively shaped by fi lters to arrive at the desired sound. Basically all subtractive synthesizers have 2 main sections - sound sources, and sound modifi ers.

Modifi ers can be further separated into sub-sections –

Filters, LFOs, Envelopes, and Effects. There’s also the

Step Sequencer, which is a special case ‘modulator’.

With Solaris’ complex modulation pathways, it is possible to apply these techniques to generate much richer waveforms than were available to early analog synthesizers. The output of FM Oscillators can be fed back into their FM input ( Feedback FM), or to the input of an

AM Synthesis processor, or practically any other routing you can think of. Even the complex output of the four fi lter sections can be used as modulation sources for FM and AM synthesis. Each fi lter output has a ‘feedback protection’ circuit to allow self- modulation of these signal paths.

User Interface Design

Many of the areas on Solaris’ control panel are multipage. In fact, the whole front panel can be paged. In the lower left of the Solaris, you will fi nd two page buttons, Main and Seq. These ‘page out’ the Main controls for the Step Sequencer controls.

Within each of these two larger sections are many more page buttons. The different pages are accessible by clicking on the light blue page tab buttons that appear generally in the upper portion of the section.

For example, the Filter section has page tab buttons for each of the four fi lter pages, F1, F2, F3 and F4. The page tab button for the page you are viewing will be dark blue. In addition, there are tiny blue LEDs above each area that indicate which of the sections in that area is currently active. As a convenience, you can activate/deactivate a section by clicking on the blue LED without having to be on that page. Sections that are not active do not contribute to the DSP load. (A complete list of the names identifying each of the tiny, blue LEDs is given in the Appendix.)

Many of the knobs have text labels underneath their displays to describe their function. There are also many knobs that have a small, rectangular ‘grayish’ box in place of the text. These are popup lists for the knobs’ parameters, and are different according to their particular function.

For example, in the picture above, you can see that

MM Osc 1 has three knobs right below the MM Osc 1 label. The fi rst is a permanent control over the Coarse

(semitone) Tuning for that oscillator. The second and third knobs each have a popup list associated with them, and above them there is a label called ‘Freq

Mod’. The knobs are bipolar (range is +/- 63), and control how much of whatever is selected in the popup list will modulate the oscillator’s frequency. (Though not labeled as such, these are ‘Freq Mod 1’ and ‘Freq Mod



Likewise for the Filter Mixer section – the fi rst four knobs are mixer inputs, and you can select from the

Source popup lists below each knob to determine the signal input for each of these.

Signal Flow

The sound sources are connected to the four inputs of each fi lter mixer. Since there are many available sound sources, but only four inputs to each fi lter section, a popup selector list is used to assign a sound source to a fi lter mixer input.

No sound will be produced at the output of a fi lter mixer if it is disabled or if the fi lter Mute button—located in the lower left corner of the synth window—for that fi lter channel is in the off position.

The sound sources are routed through the selected fi lter(s) (if enabled), then through the Pan circuit. There are several controls over the fi nal audio level of the

Solaris: the Master Volume, the Poly Level, and the

Overdrive. Of these, the Poly Level is NOT stored in the presets. The idea here is that you set the number of voices you expect to be using for most of the time, then you adjust the Poly Level so that there is minimum clipping. This handles the overall headroom of the synth’s output, so you’ll always want to check this level if you hear some clipping, but can’t determine why in the normal signal path analysis.

The Master Volume is at the end of the signal path, allowing you to have high settings for the Overdrive, without destroying your speakers or your ears! However, please be careful to not hold down notes while changing presets, especially if you are selecting a preset with high Overdrive settings, as you may hear some loud sounds during the transition.

Remember that each preset may be changing the DSP load through enabling/disabling sections, and if so will take a bit longer than the average preset change.

Table 2: Typical source popup list

An important point is that the Rotor, AM, and Vector processors do not output sound by themselves; rather, they require selecting from among the other sound sources to produce their unique output. However, for practical uses, these still act as ‘sound sources’.

The 8 Global RD Module Slots from Solaris v4.0 have been removed, and replaced by additional ‘taps’ of the audio path signal at various stages. You can now choose the source for modulation directly from the Mixer, post-fi lter, or post-VCA, making the entire contoured signal path available for feedback loops.



The Oscillator section—located on the top left of the

Main page—contains pages for each of the oscillator pairs/sound sources available in Solaris. Each page consists of a pair of oscillators (or special sound sources in the case of Rotor, AM and Vector Synthesis). In addition to controls specifi c to the type of oscillator, each oscillator section has the same modulation options available for frequency and shape modulation.

Oscillator 1 has two frequency modulation options, while Oscillator 2 has only one, with a Fine Tune control instead.

Key Tracking

Oscillator 1’s two frequency modulation paths have identical source lists, but an important functional distinction should be noted. When you select KeyTrk as the source for Oscillator 1’s fi rst frequency modulation path, you disconnect the oscillator from the normal tuning. Oscillator 1’s tuning (in relation to the keyboard) is now controlled by the amount of frequency modulation

(positive or negative) that you apply to the fi rst modulation path containing the KeyTrk source. A value of

+63 will result in a normal 12 semitones/octave range.

A value of -63 will result in a completely inverted 12 semitone/octave response. Positive or negative values between 0 and +/- 63 will result in microtonal tunings.

A value of 0 will result in no keyboard tracking applied to the oscillator, which means that the same tone will be produced regardless of the key pressed. The initial

‘center’ tone of the oscillator is controlled by the KeyTrk

Center control in the Global area. By changing the value of KeyTrk Center, you can shift the range of the keytracked oscillator over a very wide range. This feature is very useful for producing alternate tunings such as eastern tunings, etc.

Selecting KeyTrk in oscillator 1’s second frequency

modulation path has a different effect. When KeyTrk is selected as the modulation source for the second frequency modulation path, it adds the special keytrack frequency control to the existing frequency control, and will therefore produce a 2-octave range within a normal octave (12 semitones) when the amount is set to +63.

A setting of -63 for KeyTrk in path 2 will result in a ‘canceling’ of the keyboard tracking, giving a drone pitch at full negative value (-63). glissando with the samples, and when doing so, occasional pitch ‘glitches’ made be heard.

No Track, MIDI Sync, and Low Freq Mode

No Track, Midi Sync, and Low Freq Range have been added to a number of oscillator sections. Also, for the

No Trk button - all places this button shows up now bring up a wide range frequency control displayed in


You can route Frequency Mod 1 path as either Linear or Exponential control. The small LED button just above Freq Mod 1’s amount knob will switch it to Linear, when ON (green).

A side chain function has been provided for all Mod 2 paths (oscillator frequency mod, shape mod, and fi lter cutoff frequency mod), which routes the signal of the

Mod 2 source to control the amount of Mod 1’s modulation. This is enabled by switching on the oval-shaped arrow button located between the Mod 1 and Mod 2 knobs. The arrow will turn white when enabled.

Oscillator Sync

Oscillator sync causes the cycle of the slave oscillator to be restarted whenever the cycle of the master oscillator restarts. The pitch of the slave oscillator becomes locked to the pitch of the master oscillator. Changing the pitch (coarse or fi ne tuning) of the slave oscillator will cause a change in the timbre of the oscillator’s output as additional frequency components are added to the signal. Changing the pitch of the master oscillator will change the pitch of the slave oscillator.

Sync for MM Osc 1/2, RDX 1/2 MM Osc, and FM 1/2 are selectable from most other sources for sync input.

Please note that it is not actually the waveform output, but only the frequency controls form the source listed that will provide the sync master frequency. The only restriction here is if you want to use the Modular Window’s Sync signal - this is always derived from MM Osc

2’s frequency.

The following oscillators are capable of oscillator sync:

MultiMode Oscillators

CEM Oscillators

FM Oscillators

Modular Oscillators (depending on confi guration)

If not using KeyTrk, you must de-select it, as it will aff ect the oscillator’s pitch tracking otherwise.

Oscillator 2 has only one Frequency Modulation path, and this acts the same as the fi rst frequency modulation path described for Oscillator 1. Applying the KeyTrk to the Wav OSCs is the only way to get portamento or


Sound Sources

Multimode Oscillators (MM)

Figure 1: Multimode Oscillator Pair

Each MultiMode Oscillator (MM Osc) has several waveshapes, and in fact, there are several different oscillator types ‘hidden’ within the MM Osc structure. Also, there are slight differences between MM Osc 1 and MM Osc

2. Here are the available waveshapes for each:


Sine Sine

Triangle Triangle

Saw Up (ramp) Saw Up (ramp)

Saw Down Saw Down

Pulse Pulse

White Noise


Pink Noise

MorphSaw (not in MIDI Clk mode)



MorphSquare (not in MIDI Clk mode)

SuperSaw (not in MIDI Clk mode)

Since the origins of the Solaris come from the Orion

Custom (which borrowed the Prophet 5 concept for

Osc 2 modulation), you will fi nd that the MM Osc 2 appears in the modulation lists in 2 forms - unaltered and shaped:

Whenever you see ‘MMosc 2’ in the modulation source lists, it is the unaltered MM Osc 2 output.

Whenever you see ‘EnOsc2’ or ‘EnvOsc 2’, it is the output of MM Osc 2 with its amplitude shaped by

Envelope Generator 1 (EG1).

For MMosc 2, when using MIDI Clock, I assumed the user would want more precise control over the onset of waveshape events, to allow better modulation synchronization by being able to retrigger the phase (which is a way to determine where in the cycle of the waveshape the modulation will start on a note-on event). Also, when switching control to MIDI Clock control, keyboard tracking is turned off and setting to a low frequency range is done, both automatically. Therefore, these two buttons disappear. Instead, a Retrig button is displayed, which allows the user to control the phase start point with a note-on event. Also, the displays change to

MIDI Clock Division list and a Phase knob (which only matters if Retrig is on).

Figure 2: MIDI clock sync for MM OSC 1

Table 3: Multimode Oscillator Waveshapes

MorphSaw/MorphSquare – when the Initial Shape parameter is zero, these output a sine wave. As the

Shape is increased (+/-), the waveshape becomes more ‘saw’ or ‘square’ shaped.

SuperSaw is a ‘brute force’ attempt to provide a highly detuned saw mix - it actually uses 7 saw oscillators progressively detuned from one another.

There are some differences in how MM Osc 2 is used, and therefore, some ‘special case’ situations occur.

However, the actual structure of the MM Oscillator circuit does not internally provide for phase retriggering. So, to provide this I had to ‘switch out’ the regular

MM Osc 2 circuit for a retriggerable LFO, which does not provide all of the same waveshapes as the MM

Osc 2. This is why you will not see certain names in the waveshape list when using MM Osc 2 under MIDI

Clock control.


Figure 3: MIDI clock sync for MM OSC 2

The Multimode Oscillator #2 acts as the source for ‘hard synching’ of the Modular Window oscillators. When MM Osc 2 is set to Low Range or MIDI Clocks, the hard sync signal will be aff ected. However, I added a circuit so that you do not need

MM Osc 2 enabled to generate a hard sync master control.

The Coarse and Fine Tune of MM Osc 2 will still aff ect the ‘hard sync’ signal, regardless of the enabled/disabled status of MM

Osc 2 (this is only true of MM Osc 2).

When using Sine waveshapes for the MM Oscillators, you will hear clipping if the mixer levels are greater than half the range (above +/-31). In general, the MM Oscs are louder than the others.

MM Osc 1/2 cannot create ‘hard sync’ when you select the

MorphSaw, MorphSquare or the Supersaw waveshapes.

Wavetable Oscillators (WT)

Figure 5: Partial list of the 64 available wavetales

Red Dwarf EX Module Slots (RDX)

Figure 4: Wavetable Oscillator Pair

The Wavetable oscillators are from the old Creamware

Modular I Waldorf oscillator, and provide you with 63 sweepable wavetables. Sometimes ‘wavetable’ is thought to mean a single cycle waveshape, as in the

Prophet VS waveshapes. With Solaris wavetables, however, you have a series of waveshapes, 1-63, which are stepped through by moving the Wave control, or by applying some WaveMod modulation.

Figure 6: RDX Oscillator Pair

The RDX oscillator section is a multifunction oscillator section that essentially represents one each of the current oscillator types already available in the Solaris.

When you select the RDX pages, you will fi nd labels that will display something like ‘RDX1 MM’ and ‘RDX2

MM’. They could be set to RDX1 WT or RDX1 CEM, etc. These are popup selector lists that, instead of just one type of oscillator, give you one each of the current oscillator sections. This allows the user to have 4 of the same type of oscillator going on, which was not possible in previous versions of Solaris (v2.x or older).


Wave Oscillators (Wav)

Figure 7: Oscillator Types Available for RDX Slots

When you want to use these in a Mixer or Mod Source list, just select RDX 1 or RDX 2. You will also note that, unlike all the other oscillator pairings, you can independently select Osc 1 and Osc 2’s type, so you can mix and match.

Because the RDX1/2 sections can act as mod sources, they both have the ability to be MIDI sync’ed, go into non-keytrack mode, or shifted into a Low Frequency (-5 octaves) range. New for all oscillators that have the No

Trk button is that the coarse and fi ne tuning (where active) are now replaced with a fi xed wide frequency knob which displays the settings in Hertz. (Prior to this they were fi xed at a certain frequency). If you made any presets with Low Freq switch on (say, for MM Osc2 or

Rotors), you will most likely have to remake it to adjust for the new frequency in Hertz parameter. (More about presets below.)

Of course, the standard RD slots are still available. RD slots allow you to incorporate the semi-modular RD

(Red Dwarf) Modules Series II (purchased separately).

These are user-confi gurable oscillators; using these, you can duplicate the Multimode, Wavetable, Rotor, or Modular sections, or make very complex groupings

(stacks) of oscillator modules, all by loading any of the custom RD series II oscillator modules.

The RD slots can be loaded either by right clicking with the mouse pointer over the insert slot, or by dragging and dropping in a module from the File Browser.

More is explained in the section, Expanding SOLARIS with RD Modules.

Figure 8: Wave Oscillator Pair

These oscillators allow the loading and playback of sample fi les. Formats are Akai .s, AIFF, and .wav. The slots load single, monophonic samples, and the two

WAV oscillators cannot be phase locked, so true stereo phase coherent sample playback is not possible.

Control Description

Load Sample Clicking this button will bring up a load dialog; sometimes this window is not visible, as it does not come up

'on top' of some SFP windows.

Clear Sample clicking on this removes the sample fi le



Low Key, below which the wav osc will not play

Root Key. This sets the base pitch of the sample playback. This is ignored if ‘Fixed’ is ON




High Key, above which the wav osc will not play.

When this switch is ON, the root key setting is ignored, and playback is at the originally sampled pitch

This is a 12 dB gain boost to the output of each Wav Osc, prior to entering any Filter Mixer

Table 4: Wave Oscillator Control Parameters

Since sample fi les are stored in your computer’s RAM, and not in the DSP card, frequency modulation is done at host processing speeds, so you will fi nd a much more grainy result when modulating these, especially at fast LFO rates, when the host cannot keep up with the frequency demands.

Modular modules as needed. (Each Window has a text fi eld labeling it as ‘Mod1 Slot’ or ‘Mod2 Slot’.)

Figure 11: Modular Window

Figure 9: CEM Oscillator Pair

The CEM oscillators are the same as in my Prophet

Plus and Pro One emulations, however, because of major differences in the signal chain design of Solaris, the output of this oscillator pair is much ‘quieter’ than the other oscillator choices. This is because the CEM oscillator is actually an optimized block that produces 6 simultaneous waveshapes, and therefore, divides the dynamic range to avoid clipping if the maximum mix levels for all 6 waveshapes were applied. To compensate somewhat for this, I have added boost controls after each fi lter, as well as an override to switch off the

Pan circuit (which reduces the gain as an averaged signal as well). It comes out to be about 22 dB less for each CEM output, which is considerably less than the

MM Oscs, for example. Even using the boost, you will sometimes fi nd an overloaded or saturated (extremely

‘clipped’ or distorted) sound when trying to increase the level for these oscillators, so please be mindful of this affect.

Each Boost starts at a displayed value of 2.5 dB. This matched the signal level when the fi lter was bypassed, so I set it as a minimum setting for the Boost.

Modular Oscillators ( Modular)

Input Description

Freq Frequency control. This includes the Coarse and Fine tuning, and any Frequency Modulation assigned from the front panel section.

Shape Waveshape control. This receives the Initial control amount and two modulation sources for Shape Mod from the front panel section.

Note This is a numeric value called Note generally used to control key tracking modules.

For oscillators it would be used with the

Wav Osc module.

Sync This provides a signal from Multimode Osc

2 as a master sync tone for hard sync'ing

Modular oscillators. The Coarse and Fine settings of MM Osc 2 are used to set the fundamental frequency.

Figure 10: Modular Oscillator Pair

These special purpose Modular Windows allow the ultimate customization of the sound sources. To use,


FM Oscillators (FM)

(or to itself, a technique called Feedback FM), the Amp

Mod control is used to control the amount of frequency modulation. The Amp Mod control can be set by the knob or by any of the modulation sources listed in its source selector.


When using the FM oscillators to modulate the carrier similar to the DX7 (which is reportedly actually phase modulation), you need to lock the phases of the carrier and modulator wave together; otherwise you will get small inconsistencies in the sound, especially if you are generating very high harmonics. Free Run/ Gate Sync allows you to synchronize the two FM oscillators together. The Sync control also allows ‘normal’ hard sync coupling with any of the other tuned sound sources listed.

Figure 12: FM Oscillator Pair

FM synthesis generates sound by modulating the frequency of a simple waveform (the carrier) with another waveform (the modulator or operator). The frequency of the modulating wave affects the rate of change of the frequency of the carrier, and the amplitude of the modulator affects the amount of change in the frequency of the carrier. The operator’s waveform is not necessarily in the signal path, it is used to control the frequency of the carrier. Solaris has two dedicated FM oscillators, each of which produces a sine wave that acts as the carrier for FM synthesis. The more complex the modulating waveform, the more complex the waveform output by the FM Oscillator will be due to the generation of additional sidebands. It is possible to generate noise by over-modulating the carrier wave.

Figure 13: FM Oscillator Sync Options

Solaris provides two mechanisms for modulating the frequency of the carrier wave, Exponential Frequency Modulation and Linear Frequency Modulation, which allows extremely complex waveforms to be generated by the FM oscillators.

Phase Control

This control allows you to offset or adjust the phase of each of each FM oscillator, when in Sync mode.

Linear Frequency Modulation

When using Linear Frequency Modulation, the amount of modulation applied to the oscillator by the carrier can be controlled in several different ways. Each FM

Oscillator has two Linear Frequency Modulation paths.

The fi rst path allows the amount of modulation (the

FM Index) to be set by the corresponding knob. The second linear modulation path allows the initial modulation index to be set by the knob, and then a modulation source applied to that path (sidechain modulation control). For example, an LFO could be used to modulate the amount of frequency modulation provided by the carrier specifi ed in Linear Frequency Modulation path

2. In addition, if you are using one of the FM Oscillators as the modulator ( operator) for the other FM Oscillator

Special Sound Sources

Solaris provides a number of sound sources that do not actually produce sound on their own. Rather, they process the output of other sound sources in order to produce complex, animated sounds.


Rotor Processors (Rotor)

Clicking back to ‘X-Fade’ displays the initial Crossfade

(Xfade) control for the Rotor, as well as a modulation path for this parameter. The higher the crossfade number, the smoother the transition from one input to the next will be.

One unusual way of generating new harmonic structures is to run the Rotor at audio rates, tracking the keyboard. This is almost like a ‘granular’ approach in that you will hear small bits of each input at a rapid rate. As mentioned, increasing the crossfade in this case gives the impression of a ‘less bright’ harmonic content, as the crossfade smoothes out the ‘rough edges’ of the resultant waveshape.

Figure 14: Rotor Processor Pair

The Rotor object is a module created by Michael Ruf, former product manager at Creamware. His idea came from the rotary engine model, which has 4 power cylinders, and where each cylinder’s explosion sends the rotor on to the next position.

In the Rotor circuit here, there are no explosions (well, maybe sonically!), but the concept of continuously moving from one cylinder to the next is in force. Here’s how it works:

There are four inputs to the Rotor. Each is presented at the Rotor’s output in series, one after the other.

(You can think of it as a 4-step wave sequence, where each step’s sound comes from one of the many sound sources in Solaris.) The XFade ( Crossfade) control

‘smoothes’ the transition from one step to the next, and does it uniformly for all four inputs. If the XFade amount is zero (0), then the transition from one step to the next will be abrupt; at full amount (127), each step is crossfaded with the next, providing smooth but constant changes in the output. When the Rotor runs at audio rates, the transitions happen so quickly that we hear the results as a unique waveshape itself – one can change either the coarse and fi ne tunings of each input, or the source material itself to create timbre changes.

You’ll also fi nd (at audio rates) the Xfade amount makes the waveform less bright as you move from zero to max amount, as the smoothing function takes off the

‘rough edges’ of the resultant as it is increased. Additionally, a modulation path is provided for modulating the Xfade amount.

AM Synthesis (AM/ xMult.)

Figure 15: AM Synthesis Section

Amplitude Modulation (AM) is a process of varying the amplitude of one sound (the carrier) by the amplitude of another (the modulator). If the frequency of the modulator is sub-audio, AM results in a tremolo effect. If the modulator’s frequency is above around 10hz, the timbre of the carrier is affected by the introduction of additional partials to the output. When two sine waves are used, AM results in two additional sidebands equally spaced around the carrier’s fundamental frequency.

The frequency of the sidebands is the sum and difference of the carrier and modulator’s frequencies, and the amplitude of the new partials is half the amplitude of the carrier.




Typical AM that produces two sidebands around the carrier

There are two page buttons in the upper right section for each Rotor – Mixer and X-Fade. Clicking on the

‘Mixer’ button switches out the display to show four small mixer knobs. These allow you to precisely set each level of the four inputs, in the case of an imbalance of levels from the sound sources. Also, the mix levels are bipolar, for inverting the phase of the incoming signal.




Abs (absolute)



Multiplies the two input signals and clips the result. Creates two strong sidebands (stronger than those generated by Shift) around the carrier's frequency, and on strong sideband at a much lower frequency. Phase cancellation eliminates the original


Outputs the absolute value of multiplying the two input signals without clipping. Creates two weak sidebands widely spaced around the carrier.

Classic ring modulation that creates two strong sidebands around the

carrier and eliminates the carrier completely due to phase cancellation.

‘multiplied’ signals will be cross faded

Source goes to both inputs

Source goes to 1 input, with the output of the fi rst ring mod mult to the second input

Source goes into one input, with the output of the factor 2x into the second input

Source goes into one input, with the output of the factor 3x into the second input

Source goes into one input, with the output of goes factor 4x into the second input

Table 8: Effect of the xMult Factor setting

Solaris allows many diff erent signal sources to act as carrier and modulator for AM synthesis. Table 7 describes the eff ect of each AM algorithm in terms of a sinusoidal carrier modulated by a sine wave. Since sine waves are the least harmonically rich waveforms, it is easier to understand the functions of AM synthesis using them as examples.

With certain combinations, you will get identical results for some of these algorithms, depending on the position of A and B (A x B, or B x A, or which is the modulator and which the carrier).

Using waveforms other than sine waves will result in additional sidebands for each frequency component of the carrier, which allows very complex waveforms to be generated.

X Mult (multiplier)

These are four identical circuits that can be used to multiply an input signal by itself, using ring modulator modules. This technique can be used to produce extremely exaggerated, or “exponentiated”, control signals, such as the old DX7 trick of running an envelope into both inputs of a ring modulator (a multiplier) to get an exaggerated taper and long decay time on the envelope. Note that this technique does not work well with

Attack times. The x Mults on Solaris 5 also allows you to cross fade between the original and the multiplied output, giving very fi ne control over the slope shape.

Another use for the x Mults is generating organ-like sounds by generating multiple octaves of sine waves.

By using a sine wave as the input to both x Mults, you can generate octaves above the source by taking the output and multiplying it again and again, for the different octaves. The Mult Factor control allows you to specify how many times the signal is multiplied.

Vector Synthesis (Vector)

The Vector Synthesis section allows four different sound sources to be mixed/morphed dynamically based on a 2 dimensional x/y vector graph. Vector

Synthesis allows Solaris to achieve swirling, moving dynamic sounds reminiscent of the Sequential Circuits

Prophet VS. Each corner of the control represents the full level of one of the four input sources. The joystick control can be assigned to a hardware MIDI controller or modulated by any of Solaris’ extensive modulation sources.

This section has two pages selectable with the Mixer/

Vector buttons:

Figure 16: Vector and Mixer controls

The x Mult sections consist of:

The input selection (Source)

The number of times you multiply the signal by itself

(Mult Factor)

Like the Rotor, the Vector mixer has four inputs, each of which can be selected from a very long list of sources

(see below). Like all mixers in the Solaris (and identical to the Rotors), each input also has a bipolar Level

control. (Negative amounts increase the level from -1 to

-63, but with the phase inverted.)

Switching the display by using the Vector button (next to Mixer) shows the X/Y pad, with the mixer controlled by the small gray dot. Grabbing this with the mouse will move the mix accordingly, from corner to corner, etc.

When you move the gray dot, you will see the 2 sliders

(X and Y) move concurrently. If you want to control the

Vector Mix with some external MIDI controls, just rightclick over each slider to assign a Midi Controller value.

(Save your MIDI Controller settings in the special “MIDI

Controler” bank of your Solaris preset list.)

You can also modulate either axis from the standard list of modulation sources. There is one modulation path for each axis (X and Y). The white dot is not selectable, and only functions to show the position of the mix when

modulation is applied.



Sound Modifi ers

Solaris provides an extensive array of sound modifi ers to shape the frequency, harmonic content, and amplitude of the included sound sources. Four LFOs provide repeating waveforms for periodic variation, with a fi fth ‘LFO mix/blender’ section providing more complex combinations of these. Four fi lters provide a wide variety of subtractive methods to affect the harmonic content, and 6 envelope generators provide customized

modulation control signals based on note-on ( Gate) triggering. A new Control Shaper function provides an interpolation table for modifying existing modifi ers sources.

Additionally, there are routings to provide control of these modifi ers from such standard keyboard controls as aftertouch, velocity, key tracking, and the sequencer.

In addition, all of the oscillators, and each of the 4 fi lter outputs can be used as modulation sources, allowing for complex feedback paths to occur. Finally, there is a

3x16 step sequencer. Each of the three sequence rows is selectable in the modulation source lists provided for almost all modulation paths. All knobs labeled ‘Freq

Mod’, ‘Mod 1/2/3’, ‘WaveMod’, ‘Shape’, etc., have control over some a dynamic aspect of the sound, and most have a Mod Source popup list associated with them. The standard Mod Source list will contain the following entries:

The Envelope Follower is used to convert the amplitude envelope of an audio signal into an envelope signal that can be used within Solaris as a modulation source.

Shorter Attack and Release times will cause the Envelope Follower to more closely follow the incoming autio signal. Input and Output Gain allow you to pad the gain of weak input audio and control the level of your output control signal. The Envelope Follower is on the Mix/

Blend page (MIX) in the LFO section.

Figure 18: The Filter Section Panel

Solaris has four fi lters that are mixed in parallel. There are also four mixers, one for each fi lter, so that you

20 | SOUND MODIFIERS can have a different combination of sound sources sent to each of the fi lters at the same time. There is a gain boost after the fi lter signal, and the signal output path from each fi lter is then sent to the pan and level section. (If the upper Filter section is disabled, the raw

Mixer output is sent to the pan and level sections.)

Each Filter Level can be controlled by a knob on the surface, by any of the envelopes, or any of the other modulation sources listed. Using these, you can create separate articulated shapes for each fi lter’s output - almost a ‘multi timbre’ approach to the sound, enhanced by the fact that each can also have its own envelope and pan position.

With the Filter outputs as possible signal inputs, you can create feedback loops within each fi lter section, or have the function of series fi lter connections (the fi lter output is taken before the pan module, so the series fi lter signal’s panning is determined by the last fi lter in line). You also can get some useful and strange distortion of the fi lters if desired, among many, many other things!

Filter Page Views

The Filter Section has two main views, the main Filter

Filter Type



Similar construction to the Comb fi lter, with a higher level of resonance achieved, and better for modeling the Karplus-Strong ‘plucked string’ algorithm. Tube fi lters are particularly effective when imitating sounds such as a fl ute (from which the module got its name, since a fl ute is little more than a ‘tube’). To produce a fl ute sound, you would start by sending some noise to the resonator. Modulation inputs provide signals to control the spectrum.


Filter Type



The comb fi lter is essentially a delay with feedback, but the input signal is not passed through. It emphasizes (resonates at) frequencies that are multiples of a hertz. A comb fi lter attenuates frequencies at several regular frequency intervals. If you look at a signal that has been processed by a comb fi lter in a spectrum analyzer, you will notice several ‘notches’ where the signal has been cut. A graphic of the frequency response strongly resembles a comb, hence the name.

This fi lter is essentially similar to an equalizer bell fi lter, but has a varying-width pass/stop band of two octaves at the lower end of its frequency range and one octave at the upper end. Changing the fi lter frequency thus also dynamically changes the width of the pass/stop band. The fi lter can boost or cut signal level by up to 24 dB within the pass/stop band.

This fi lter is essentially similar to an equalizer bell fi lter, but has a varying-width pass/stop band of three octaves at the lower end of its frequency range and one octave at the upper end.

This fi lter permits the complete suppression of specifi c frequencies without affecting nearby frequency ranges. Only frequencies directly around the cutoff frequency are removed. The frequency response curve exhibits a deep notch at this frequency. With this fi lter, the resonance parameter adjusts the notch width. In addition, at full resonance, the response curve exhibits a small resonant hump above the notch frequency.

A combination of a notch fi lter and a peak fi lter, used to achieve a phasing effect. The Resonance control adjusts the peak level or notch width, increasing the intensity of the phasing effect.

A classic phaser effect, created by combining 3 notch fi lters with 3 peak fi lters. The Resonance control adjusts the peak level or notch width, increasing the intensity of the phasing effect.

This is a new type of comb fi lter that combines two notch fi lters with a bandpass fi lter. The frequency response curve is essentially similar to that of a bandpass fi lter exhibiting a notch on both sides of the fi lter center frequency. The resonance control adjusts the widths of the notches and that of the pass band. At full resonance, the notches develop small resonant humps, thereby intensifying the phasing effect.

This fi lter produces a light fl anger effect which is generated by means of three notches similar to those of comb fi lters. The resonance control here serves to intensify the fl anging effect.

Table 10: Additional Filter Types

The additional fi lter types from Solaris v4.0 are from the

Modular III Poly Filter. They are made from many combinations of the internal fi lter poles. The levels are more attenuated, so you may want to adjust signal levels with the Boost parameter. At the end of each fi lter type list you will fi nd 2 more choices:

Table 11: Red Dwarf Slot and Modular Window

Filter Routing

Table 12: Filter 2 Input Options

The Input parameter allows you to route any of the 4

Filter Mixers to the input of any fi lter. In addition, each fi lter can take the output of any other fi lter as its input.

For example, if you have Filter 2 as a high pass fi lter with some post-fi lter distortion, you can process that with Filter 1’s FX, pre- or post-fi lter as well.

Solaris’s 4 fi lters are hardwired in parallel, and each has it’s own VCA and panning circuit. The Input parameter can be used to wire fi lters in series, but it is important to remember that the output of all 4 parallel fi lters will be heard in the overall mix unless you mute all but the fi nal fi lter in the series. Muting a fi lter will take it out fo the parallel path entirely. If you desire some of a fi lter’s output to appear in the mix, you can reduce the ENV amount of the AmpEG on the Outputs page to drop the fi lter’s overall output in the signal path.

Mixer Modulation (Mix Mod)

Figure 21: Mixer Modulation Controls

Mix Mod allows you to modulate each of the 16 mixer input levels individually from the full mod source list.

The Mix Levels and Mod Amounts are independent parameters, so you can have an amount of modulation and an offset mix level.

Use the page buttons to switch the Mixer display for

Levels to Mix Modulation.

For effective modulation of the mixer inputs, you need the initial mixer level to be at zero. Then, select a mod source (such as Env 1 or an LFO), and increase the mod amount with the knob above the mod list selector. The Amounts are bipolar, which won’t always make sense, but does allow for inverted phase of the mod source. If you want to add some offset to the signal, just raise the initial mixer level for the input.

Also, because the added circuitry of the Mix Mod section takes up a fair amount of DSP , there is an Enable/

Disable button in the upper left corner of each section, below the Mixer Enable button, and is colored red

24 | SOUND MODIFIERS when on. You will need to Enable the Mix Mod for these controls to work. (When disabled, the Mixers work normally.)

Filter Output (Output)

All Mixer/Filter section outputs are mixed together to a stereo signal bus and individually sent to the modulation bus to act as a modulation source (F1 mix, F2 mix,

F3 mix and F4 mix). At times you may want to use this signal only as a modulation source, and not hear it through the main stereo bus; using the Mute buttons in the lower left bottom area of the synth will silence the mix output in the stereo bus, but keep it available as a modulation source.

This is a fairly complex issue, but here’s the thought behind it:

You can use the output of any fi lter mixer as a modulation source. If you turn on a mixer, however, it plays through the Main Mix outputs, and it is usually the case that you do not want to hear it there, but only as a participant in the modulation path (when using it as a mod source). Therefore, muting the signal from the Mute buttons will remove the signal from the audio path, but not the modulation sources.

Figure 24: Filter Output Summary Page

Clicking on the Outputs button displays a summary view of all 4 fi lters and fi lter mixers, with key parameters such as fi lter type, cutoff frequency, resonance, envelope amount and source for the mixer, etc. This provides a quick way to see what is happening with all

4 fi lters/mixers at the same time. Key parameters can be edited on the Outputs page as well as the individual fi lter pages.


There are 5 LFO sources, counting the vibrato LFO.

The LFOs are listed in the modulation source list as:

SMO (Super Mod Oscillator), lfo-a, lfo-b, and lfo-c.

There is also an LFO Mix/Blend feature allows the mixing of any 4 of these LFOs, or any of the many other control signals in Solaris, either as a standard mixer signal, or as a series of signals, one after the other via the ‘blender’ circuit. The output of the Filter Mix/Blend is listed as ‘Lfo Mix’ in the mod lists.

Super Modulation Oscillator (SMO)

This special LFO can provide more complex timbres as it can run at an audio rate and track the keyboard, thereby suitable for linear modulation of the source material. It also has more extensive controls over the amplitude – delay, fade in, and fade out. These parameters are calculated from each note-on ( Gate) event.

LFOS | 25 between each discrete step.

The SMO also has pink and white noise as possible selections for its ‘waveshape’. Using noise obviously negates the frequency controls, and in fact, only the SMO Level modulation is relevant.

Vibrato LFO (V-LFO)

The Vibrato LFO is dedicated to the vibrato effect and has its own control area on Solaris’ Main page. The

Vibrato LFO in Solaris is a multimode LFO, with most of the parameters that come with the multimode LFO added: Delayed start (DelS), Fade In control, Retrig and Phase options, and MIDI clockability.

Figure 25: Super Modulation Oscillator Panel

The SMO has the following controls over the amplitude:

Delay Start, Fade In, and Fade Out. These parameters are calculated from each note-on ( Gate) event.

Fade Out values must be greater than 0.00 – at zero, the Fade

Out circuit is ignored, and the SMO stays at full level.

When Retrigger is ‘On’, the SMO will start its modulation from the same point in the waveshape every time a gate signal is received. The Phase control allows you to set exactly where the progression of the SMO’s waveshape will start (only functional when Retrigger is on).

Bias provides a list with two choices – Offset, or Rectifi ed. Offset reduces the SMO’s output and shifts it into positive values only; Recitifed does not reduce or shift the signal, but only allows the positive portion of the waveshape to pass. (This is perhaps more useful when using the SMO as an audio rate modulator.)

You will notice the Frequency parameter changes its controls, depending on the KeyTrack switch. Without

KeyTrack, the display gives a normal frequency reading in Hertz. When the KeyTrack is switched ON, this display changes to a Coarse and Fine tuning, to refl ect the use of the SMO as an audio rate oscillator. When switching to MIDI Clock Sync, the Frequency and tuning of the SMO is overridden by the incoming MIDI signal, disabling and removing the other frequency displays.

MIDI Clock Sync switches the frequency control to a popup table of note values/divisions. See the MIDI

Implementation section for a description of the values.

Quantisation takes the incoming signal from the SMO and divides it into discreet amounts, so that the continuous analog signal is ‘stepped’, providing a series of pitches or notes. The greater the Range setting, the wider the quantisation occurs; the Steps setting controls how many semi-tone intervals are to be calculated

Figure 26: Vibrato LFO Page 1

Figure 27: Vibrato LFO Page 2

Figure 28: Vibrato LFO Page 3


Auxilliary LFOs ( LFOs)

Figure 29: Vibrato LFO Page 4

If you use Retrig, the LFO is switched to polyphonic mode, as retriggering is polyphonic by nature.

New: Additional depth modulation, rate modulation, and a separate controller table for the Mod

Wheel as it applies to the Vibrato LFO.

Figure 30: Auxilliary LFO Panel

Each of these auxiliary LFOs are identical, and provide the following waveshapes: Sine, Square, Saw Up, Saw

Down, Triangle, and Random. The blue LED loads/unloads their calculation from the DSP .

As in the SMO, Offset reduces the signal and shifts it all into the positive quadrant. (Useful particularly with some Shape modulations.)

The Rate and Depth can be modulated from the normal list of sources (including themselves), but Rate Mod disappears if the MIDI switch (Midi Clock sync) is selected, as all frequency controls are re-routed to the

MIDI Clock. See the MIDI Implementation section for a description of the values.

There is a Retrig function (as with the SMO), and this is always activated when switched on, however, to effectively use this, one needs to have access to the Phase settings as well, which only appear when Midi Clock sync is displayed.

You don’t need to use Midi Clock sync to have the phase retriggered; you just need to use the switch to access the Phase knob. It’s a bit of an inconvenience, but there really wasn’t a good amount of space to place it (this is a leftover of the earlier Solaris version, which only allowed retrigger when Midi

Clock Sync was On, and then for all three LFOs at once).

There is also an RD slot for each LFO, with a square button to switch out the RD slot, in the event you want to quickly compare the internal LFO with the inserted

RD module.

LFO Mix/Blend/ Envelope Follower



The Envelope Follower is monophonic, and uses very little DSP , so it is always enabled (does not unload from the DSP when the LFO Mix/Blend LED is off).

Control Shaper

Figure 31: LFO Mix/Blend/ Envelope Follower Panel

This is a new concept to provide a more complex subaudio modulation signal. My thinking was, why not use the Rotor circuit to route four control signals for a more interesting, less periodic control signal? And that’s exactly what I used (please read the section on the Rotors in the Oscillator group).

Since some signals may to be attenuated, there is a mixer before the rotor block, for greater control over each input. When the Blender/Mixer switch is in the

Mixer position, the blender is disconnected and unloaded from the DSP , and the associated controls disappear from the surface.

The mixer inputs are selected from the list provided

(each input has the standard mod sources), and there are bipolar controls of each level for inverting the phase of the control signal. This gives more fl exibility when combining several LFOs, or using the same LFO in both phase positions.

The frequency of the Blender can be modulated by the one modulation path, or synchronized to MIDI Clock.

Frequency controls disappear when MIDI sync is on.

The Blend knob adjusts the smoothing of the crossfade as one signal transitions to the next.

An amount of zero will allow the control signal to abruptly jump from one to the next. A setting of 127 gives the maximum crossfade possible.

This section also holds the Envelope Follower, only for lack of screen space elsewhere. Though not an LFO

(technically, this should be located in the Envelope

Section), the Envelope Follower provides a varying control signal for modulation purposes, and can be found in the modulation source lists as Env Foll. It tracks a Source input, selectable from a number of

External or Internal routings, and allows you to create an envelope based on the amplitude changes of the source material.

Figure 32: Control Shaper Panel

The Control Shaper allows you to change the “shape” of any modifi er by re-interpolation. This is accomplished by using up to 18 break-points, which can be used to program a completely different output function or curve for any incoming function or curve. The input source is divided into the selected number of points, and then each point’s actual value is re-defi ned by the same numbered knob value. The Control Shaper can modify bipolar or unipolar inputs, outputting the same.

A Control Shaper Preset List is available to store your favorite settings, independent of the Instrument or Performance presets.

New for v5.0 is a Smoothing function, that processes the output signal with exponential lag.

Envelope Generators

The fi ve ADSR envelopes are fully assignable and available in the mod source lists. (There is also a special Looping Envelope – see below). Each segment can be controlled by several mod sources, and can be set to MIDI clock sync. Each has variable attack and decay/release slopes. All fi ve envelopes can be ‘replaced’ by using their RD module slots (as explained in the RD

Expansion section).


Figure 33: Envelope Generator Panel

Envelope Generator Segment Modulation

Each envelope segment can be modulated by a number of sources – Velocity, Keytrack, Mod Wheel, CC

1-4, and RD Slots 1-8. A negative amount will cause shorter time values with higher velocities; a positive value will cause longer values with higher velocities.

Careful adjustment and balance between the initial segment’s settings and the mod amount is usually needed to obtain desired results. Shorter time values will limit the noticeable effect of velocity modulation.

With Segment Mod at zero, the actual segment time/level is heard. With the amount at +127, maximum velocity will give results equal to the actual (original) time/level setting. If time values longer than the initial setting are desired, you must fi rst set the velocity mod amount, and then adjust the initial setting to achieve desired results.

Likewise for amounts of negative value - when at –127, minimum velocity will yield the original settings, and higher values will be ‘shorter’ than the initial setting.

Figure 34: Amplifi er Envelope

All fi ve envelope generators are of the same ADSR type. Envelopes 1 through 4 and the Amp Env are freely assignable through the modulation paths. A Hold switch in the AmpEnv allows the amplifi ers to be ‘open’ without a gate or note-on event. This is useful if you are processing the external audio inputs through the fi lters or effects, and don’t want to have to hold down a note while manipulating the various parameters. It also allows you to use the Amp Env as a more independent modifi er.

Attack time for all envelopes ranges from 0 to 20 seconds. For Decay and Release the range is 0 to 40 seconds. The Velocity parameter controls the overall amount of the envelope to its destination. Higher values require a greater velocity to reach their maximum value. Atk Slope controls the slope of the Attack time;

0 is linear, 127 is exponential. D/R Slope controls the slope of both the Decay and Release together; 0 is linear, 127 is exponential.

Envelope Generator RD Slots

Each envelope has an RD slot, allowing the user to replace the normal ADSR envelope with any of the

RD series II envelope modules (such as the looping,

MultiSegment envelope). When the envelope’s RD slot is loaded, the Velocity Mod and Slope controls are ignored, as these parameters are not available for RD slot modules.

Unfortunately, there is a permanent bug in the graphic object that displays the number of points and values for the RD

MultiSegment Env module . This means that sometimes the graphic will correctly represent that which was programmed for the preset, but other times the display will not be correct, even though the MultiSegment Env output is correct. However, it is also the case that the changed graphic display will aff ect the actual envelope output.


Looping Envelope (LpEG)

Table 14: Looping Envelope Panel

The Looping Envelope is an 8-stage bipolar envelope with looping capability. This envelope can be selected as a modulation source for any other modulation destination. A Loop Envelope Preset List is available to store your favorite settings, independent of the Master

List presets.

New is the ability to control each timing segment from MIDI clocks.

Control Description

Time1 – Time8 These controls determine the length of each of the 8 segments of the envelope. The default range of the time controls is .004 sec

– 5 sec, but these values can be overridden by clicking in the fi eld and typing a number. Much longer envelope segment times can be entered in this way.

Time Mod This control determines how much

modulation will be applied to the time values of the 8 envelope segments. The modulation source can be selected from the popup menu below the Time Mod control. The range for this control is -/+ 63.

Level1 – Level8 These controls determine the amount of modulation applied to the modulation destination by each segment of the envelope. Since this is a bipolar envelope, the range of these controls is -/+ 127.

Control Description

Level Mod This control determines how much

modulation will be applied to the amount values of the 8 envelope segments. The modulation source can be selected from the popup menu below the Level Mod control.

The range for this control is -/+ 63.

NOTE: if no level modulation is desired, make sure OFF is selected as the mod source, otherwise the envelope may not appear to function.

Loop Mode On This button enables/disables the looping feature of this envelope.

When enabled, the envelope will loop between the segments specifi ed by the Loop Start and KO Point controls.

Loop Start

KO Point

When Loop Mode is enabled, this control determines the starting point of the loop. The envelope will play as normal up until the KO

Point, then loop back to the segment indicated by this control. The loop will continue until the key is released, at which point the release phase of the loop is activated, from

KO Point through segment 8.

This control serves two purposes.

When Loop Mode is active, KO

Point determines the last segment in the loop. KO Point also defi nes the beginning of the release stage of the envelope. If Loop Mode is off, segments 1 to KO Point represent the attack and decay portions of the envelope. The KO Point represents the Sustain portion.

Segments following the KO Point represent the release phase of the envelope. When Loop Mode is on, the envelope behaves as described above.

Table 15: Looping Envelope Controls

The following diagram illustrates the workings of the looping envelope.

Cross Flanger (Flanger)

Cross Delay (Delay)


Figure 36: Cross Flanger Panel

A fl anger is simply a chorus effect with the addition of a feedback loop. Solaris’ Cross Flanger is actually two different types of fl anger: a normal stereo fl anger, and a cross fl anger. The standard fl anger algorithm implements two fl anger circuits—one for each stereo channel—with a feedback loop into their own inputs.

The cross fl anger algorithm uses two fl angers whose feedback loop is connected to the input of the other fl anger.

Figure 37: Cross Delay Panel

The Cross Delay effect in Solaris is actually two different delay effects, a ‘normal’ stereo delay and a cross delay. The standard stereo delay consists of two delay circuits (left and right) that have feedback loops into their own inputs. The cross delay features two delay circuits whose feedback circuits are ‘crossed over’ into the inputs of the other delay, creating interesting panoramic effects.

Formant Filters (FormF)

widest bandwidth around the center frequency. 20.0 is the maximum, giving the narrowest bandwidth.

The 3 Band EQ circuit can be placed before or after the Overdrive circuit, using the routing switch.

New: A graphic display has been added to give an idea of the EQ settings. You can also edit the

EQ parameters from this graphic.

Figure 38: Formant Filters Panel

The Formant Filters in Solaris v5.0 are the same as the

“Vocal Filter” Modular II module. The Formant Filters are at the end of the signal path, and are comprised of two identical monophonic modules. The fi lters can be controlled independently or as linked monophonic modules, by selected between “Stereo” and “Mono

(Linked)” via the toggle switch. When operating as independent fi lters (Stereo mode), you can switch the entire control panel by fl ipping the “Left/Right” toggle switch.

The Formant Filter consists of 5 vocal formants in series in a panning mixer. Each of the 5 formant slots allows you to select from among 10 common vocal sounds, A, E, I, O, U, etc.. Moving the Initial Xfade

(crossfade) knob allows you to hear each formant as you pass along the line, crossfading from 1 to 2 to 3, etc. You can modulate this Xfade position from the

Xfade Modulation path. Play with the initial setting to offset it when using negative modulation amounts, etc.

All of the formants’ base frequency is controlled by the

Frequency Offset control. Moving this higher or lower will shift all 5 formant frequencies up or down. This parameter can be modulated by the Frequency Modulation Path.

3 Band Equalizer (EQ/OD)


The Overdrive circuit produces a ‘hard clipping’ of the

Poly Level output. Use extreme caution very high settings, as it may damage your speakers or ears. The

Overdrive circuit can be placed before or after the 3

Band EQ, using the routing switch.

FX Insert/BP Noise/CC (Misc.)

Figure 40: FX Insert/BP Noise/CC Panel

Control Description

FX Insert Up to 3 stereo effects can be loaded into these effects slots. Right-click in the slot next to the Active button to load or remove an effect, or to open its control surface or preset list. The Active button toggles the insert effect on and off. The dry and wet knobs control the dry and wet mix of the insert effects, independent of the dry/wet mix of the effects themselves.

Search Path This parameter is connected to all the

RD slots in Solaris; it is used to defi ne where the system will search for modules when the ‘right-click’ option for loading RD slots is used.

Figure 39: 3 Band Equalizer Panel

Each band has a possible center frequency setting from 20-20,000 Hertz. A cut or boost of 12 dB per band is available. Q controls the bandwidth of the cut or boost; 0.7 is the minimum Q setting, and allows the


CC Knob



These four knobs are freely assignable MIDI Controller knobs. Rightclicking over each knob will bring up the MIDI Ctrl Assignment Window, and you can add or subtract a controller assignment from here. Simply moving a MIDI hardware controller will enter the controller number desired, and the clicking on the Midi+ or Midi- will assign or delete it from the selected knob. (For more detailed control, click on the blue icon to ‘Open Control

Ranger’. This will allow you to see all of the assigned controllers, and set a

modulation range for each.)

Use the default preset bank called,

“MIDI Controller” to store different

MIDI Controller assignment presets of these knobs.

Filtered (BP)


The CC Knobs appear in the modulation source lists, and therefore any

MIDI Controller can be used as a

modulation source.

The fi ltered noise section allows you to choose from several fi lter types to process the noise signal. 6 dB LP, 6 dB HP, 12 dB BP, and a non-resonance Comb fi lter are provided. You can modulate the fi lter cutoff from a

Mod Source list. Filtered noise appears as FiltNoiz in the modulation source list.

Global Settings

The Global Settings section is arranged into 6 tabbed pages, which can be accessed by clicking on the page buttons at the top of the panel. To access pages 3-6, click on the More button. Click on the Back button to access the page buttons for pages 1-3.

Tuning and Unison (Tune/Uni)

Figure 41: Tuning and Unison Panel

Control Description

Note Priority When in Unison mode, note priority determines which key pressed will have priority, i.e., which note will be sounded. In Low Note mode, the lowest note played on the keyboard will sound. In Last Note mode, the most recently pressed key will have priority.

The early Minimoogs had a low note priority; most synths now use Last

Note priority.

Legato Mode Determines if a voice is retriggered when it is stolen for use in legato mode or not. When Legato mode is

Off, only the most frequently pressed key will sound. In Legato mode (reassign or retrigger), a key that is held down will re-sound after another key is played and released. Reassign mode reassigns the voice to the original note, resulting in a legato effect.

Retrigger mode retriggers the original note.

Env Reset Shutdown mode forces the envelopes to be reset to zero for each new noteon event. In Running mode, the envelopes continue running from wherever they are currently when a new key is pressed.







Master Fine



This should normally be set to All, however there is an ‘intelligent assignment’ if you want to stack unison voices. If the synthesizer is set to play

12 voices in your Project, then setting the Unison Voices parameter to

6 will give you 2 playable notes, each with 6 voices stacked together. The

Unison Detune then acts as a tuning spread, and each of those 6 voices will be more and more detuned from one another as this value increases.

If you set the Unison Voices to 4, then you would have 3 notes with 4 voices stacked on each. A Voice setting of 2 would give you 6 notes, with 2 voices stacked on each key.

This controls how much pitch bend will occur at maximum pitch wheel excursion (in semitones). Since most pitch wheels are centered, this is a

+/- amount. For example, a value of

2 provides for a whole step of pitch bending in either direction

Shifts the tuning entire synthesizer +/-

36 semitones. The Transpose amount is stored in the presets.

Applies +/- 100 cents tuning to the entire synthesizer. This parameter is not stored in presets. This is because you may want to play the Solaris along with an acoustic instrument that is not at concert pitch, and cannot be retuned easily (such as an old piano).

You can set the Fine Tune as needed, and still select through the presets without resetting this parameter.

Table 1: Tuning and Unison Controls


PolyGlide (Glide)

New: Independent Exponential Glide

Figure 42: PolyGlide Panel

Independent exponential glide on a per oscillator basis has been added to v5.0. The previous Glide function

(which is linear) is now the Global Glide Mode settings. The individual oscillator glides settings (called

PolyGlide) have the following parameters:


PolyGlide On/



Individual oscillator settings

All 1/All 2


Enables/disables the entire

PolyGlide section for typical preversion 5.0 operation

Allows you to select from a variety of modulation sources that will affect the glide timing values for all PolyGlide settings. There is a bipolar Mod Amount control.

The glide amount for each oscillator is controlled by the associated knob, i.e. MM 1 is the MultiMode Osc

1, and so on. Unfortunately, there wasn’t room to add a value display for each knob, but the basic range is from a few milliseconds to about 4 seconds.

Sometimes you may want to quickly adjust all of the same members of the oscillator pairs, without having to change each individual knob. There is an Enable button for this feature at the top of the section. Once enabled, the All 1 or All 2 knob values are applied to all of the fi rst or second members of the oscillator pairs.




The global glide mode setting: Portamento, Glissando, fi ngered Portamento, fi ngered Glissando.

Glissando is ‘quantized portamento’.

It’s as if you were sliding your fi nger up a guitar neck, with discreet semitone intervals being played as you slide.

‘Fingered’ means it only glides when legato notes are played (you play a new note before lifting off the old note).

Table 2: PolyGlide Controls

There is also a new section that allows an exponential type glide for each of the oscillator sections. This gilde rate can also be modulated. Adjustment can be individually, or by group –

All A oscs, and all B oscs. There’s also a Enable/Disable button for the individual glide (PolyGlide) function.

Filter Cutoff Tracking (FcTrack)

Figure 43: Filter Cutoff Tracking Panel

This new section, Filter Cutoff Tracking, takes each fi lter’s Keytrack settings (which was previously displayed per fi lter in the Misc. section) and allows quick and easy adjustment at a glance. The Keytrack Note is the point around which the keytracking occurs, and is global for all fi lters.

This signal is routed to all 4 fi lters. The Note number is the MIDI note number around which the key tracking is centered. The Gradient is a percentage that controls how steep the slope of the control value is across the keyboard. 100% produces ‘even tempered pitch’ to the fi lters, especially useful when a fi lter is in full resonance, and being used as a simple sine oscillator.

The Gradient parameter is now separate for each of the 4 fi lters. The Note value, however, must remain the same for all four. The Gradient knobs changes with each fi lter page as selected.



Figure 44: Tables Panel

Previous to v5.0, there was only a table provided for

Velocity response. Now you will fi nd separate tables for the Mod Wheel (MW Table) and Aftertouch (AT Table) control signals as well.

In each of the corners you will see small numeric displays. The lower two are MIDI Note values; the upper values control how much the note value is scaled

(should be a percentage, but for simplicity I used 0-127 for everything, where 127 = 100%).

You can click on the vertical bars and drag them left/ right, setting the upper and lower key limits for the table. Clicking directly on the blue dots, then dragging them up or down allows one to adjust the scaling.

Because these use the same graphic display as the MultiSegment Env in the Scope library, there persists a graphics bug in the preset settings. The numeric fi elds will always represent the accurate preset value, but the graphic may not refl ect these values all the time.

The Mod Wheel table output here is sent to the Modulation

Source list; there is another Mod Wheel table in the Vibrato

LFO section exclusively for the Vib LFO control.

Modulation Chains (ModChn)

Control Description

Type There are 7 types of velocity tables available, numbered 0-6. The display will give you an idea of the shape. Inverted velocity tables are provided.

Intensity Increases the curvature or slant of the selected table

Offset The bias offset of the current table’s values. Emphasizes (or deemphasizes) the impact of the table’s shape.

Table 3: MW, AT, Vel Table Controls

Your MIDI keyboard controller may also have its own velocity curves, which you will want to adjust fi rst. Use table type 0 when checking your keyboard controller, and then adjust the

Solaris velocity table to your particular playing style.

Key Level (KeyLv)

Figure 45: Key Level Panel

Four keytracking (Key Level) tables have been added as control signals (Mod Sources). These take the normal Note input and scale it across the table as output.

Key Level appears as KeyLv1-KeyLv4 in the mod source list.

Figure 46: Modulation Chains Panel

Modulation Chains are another new feature in Solaris

5, which provides additional modulation control where the current modulation path is limited, such as with fi lter resonance, which normally can only have a single mod source. This section consists of three ModChains, labeled 1-3 vertically on the right side of the panel. Each

ModChain has three inputs with amount controls. Each of the three ModChains can act as either a 3-input modulation mixer, or a modulation mixer with sidechain control. Clicking on any of the + boxes change it to an arrow, which now routes the source on the left as a controller for the source to it’s immediate right.

Refer to the screen shot when reading the following section:

ModChain 1 is confi gured as a 3-input modulation mixer. Select a modulation source and set the amount. The + sign indicates that the modulation sources are being added in the mixer.

ModChain 2 is confi gured as a 2-channel modulation mixer (lfo-a + SMO) with sidechain modulation of lfo-a by Env1.

ModChain3 is confi gured as 1 modulation source

(Seq B) with 2 sidechain controls (Seq A and Env 2)

Step Sequencer


Figure 47: Step Sequencer Page 1

Figure 48: Step Sequencer Page

Solaris’ Step Sequencer allows you to develop complex, pattern-based sequences that can be used to control the vast modulation possibilities of the synthesizer. The Step Sequencer comprises 3 separate sequencers, SeqA, Seq B, and Seq C, each programmable with up to 16 steps, and a global control section that determines how the sequencers are triggered and synchronized, which envelope generators are affected by each sequencer, and what pattern the sequencer will play.

Regarding use of the Sequencer - there were several times I wanted to have the sequenced sound play with normal Amp Release times, but unfortunately there was some problem when Sequence HOLD switches were set ON, and you stopped the sequence advance at that point (the synth would drone on and on, since the

HOLD was ‘high’, leaving the Amp ‘open’). In the end,

I decided to make it so that the sequencer only plays when a key is held (note on event coming in), with all sound being “choked off” when all keys/note offs were sent. This is not always desired, but it seemed to be generally the best compromise.

The sequencer can be stepped from an incoming note or external signal input.


Global Controls

MIDI Clock Settings

to the next step. When Ext L Trig Level is selected, the input signal connected to the External Left input will create a trigger depending on the threshold set (ExtL

Trig Level). Reset will move the sequence to start at the fi rst step of the sequence.

Figure 49: Step Sequencer - Internal Clock

The step sequencer can be cycled through its steps via

MIDI Clock, MIDI Note, or External Gate signal.

MIDI Clock: the step sequencer can be synchronized to Solaris’ internal MIDI clock by enabling the Int Clock button (default). You can then specify the BPM, clock division, and swing amount for the steps in the sequencer. The division and swing setting will affect Seq

A, B and C, however Seq B and Seq C can be set to use different MIDI Clock divisions. The step sequencer can also be set to synchronize to an incoming MIDI

Clock signal by disabling the Int Clock button. Note that

MIDI clock settings make in this section are refl ected in the Global Settings on the Main page.

To adjust the BPM, Division, or Swing values, simply click in the display window, and drag the values by moving the mouse.

The MIDI Clock information and displays will disappear, and be replaced with a Reset button, a Midi Note/ExtL

Trig Level switch, and a threshold knob setting with display (see screen shot next page). When Midi Note is selected, any incoming note whose value is less than or equal to the Key Split point will move the sequence

There are four banks of sequences – A, B, C, and

D. Each bank holds 8 patterns, for a total of 32 patterns per sequence ‘image’. There is a preset list icon located right below the On/Off button, and you must use this preset list to store the sequence image. Each preset holds one image (so, 8 seqs x 4 banks).

Copy & Paste - You can copy one pattern to another by using the Copy button. Pressing it takes the current pattern’s values and places them in a buffer. You then select the new pattern location, and press Paste. The

PAGE 1 CONTROLS | 39 values are copied from the buffer into the new pattern location.

Split On – you can use your MIDI keyboard (or incoming MIDI notes) to remotely control the selection of banks and patterns (see the Pattern Keys tab explanation below). To do this, you may want to isolate a lower portion of your keyboard to prevent unwanted notes to sound. When you turn on the Split On button, the Key

Split point determines the note value below which the

Keys assignments are activated. No synthesizer voices are played at or below this split point.

settings until you get the desired effect.

The fourth row produces the actual control values for each sequence row. There is a difference between row

A and the B-C rows; Row A will output +/- 24 semitones, whereas B and C output +/- 127 semitones. This wider range for B and C is necessary to control fi lter cutoffs or shape and pulse width parameters, since they need the full control range of the system. Using the knobs to set oscillator pitches with row B and C is a lot harder this way, so typing in the values directly is usually the most effi cient way to enter precise sequence values.

To adjust the Steps or Swing values, simply click in the display window, and select new values from the popup list.

There are independent Reset buttons for each section of both sequencer pages. This resets all parameters to their default position.

New: an exponential Lag control has been added for each sequence row output, producing an overall slewing or ‘gliding’ of the control signal.

When the Split On button is on, the note values displayed here will be used to automatically select the associated Bank or Pattern. Setting Bank B to 60, for example, will select Bank B when middle C is pressed on the keyboard. These only function when Key Split is

Refer to the fi gures at the beginning of the Step Sequencer Section.

For each Sequence Row (A, B, or C) there are 4 parameters. The topmost row is labeled ‘ Gate’. Using the check boxes, you determine if the step will send out a

Gate signal at that point. This gate signal’s duration is half the time of the MIDI clock. The Hold button causes the gate output to last for the full length of the clock, so, in essence it causes the gate to stay on until the next step that does not have a Hold button enabled. (That step is used to turn off the note, so the next gate on event will be the following step.)

The Glide function offers 3 positions - off (dark blue), linear (green), and exponential (orange). It is actually a function of an internal pitch envelope that causes the glide effect, not true pitch glide from one step to the next. There’s also a knob setting the range for each row, but the actual calculation of this pitch envelope is somewhat obscure (no explanation of it is in the Scope documentation), so I suggest playing around with these

Page 2 Controls

Refer to the fi gures at the beginning of the Step Sequencer Section.

For each Sequence Row (A, B, or C) there are 2 sets of knobs. The upper row is labeled Env Level, and controls the velocity input of the overall envelope level

(hence the values of 0-127), using the envelope assigned in the Gate Assign section.

The second row is labeled ‘Env Time’, and these values will affect all assigned envelope segments’ times simultaneously, with a bipolar amount (giving shorter or longer times). These settings interact with the initial envelope settings, and you may fi nd that you will need to adjust the initial envelope times to be the maximum you wish, with these values acting upon those initial settings.

Envelope Level (Env Level)

These values get substituted for the normal velocity control of the envelope level. At 0 value there should be no output; at 127, full output.

Envelope Time (Env Time)

These values get added or subtracted to the envelope’s segments (all segments, equally). The effect is not always noticeable, depending on the settings. The initial settings have to have enough leeway in them to


Master Volume and

Poly Level

really take notice of the Env Time modulation (hence, a very short attack time will not reveal any great change when modulation is applied).

The Solaris has two volume level knobs – the Master

Volume and the Poly Level. The Master Volume is programmable per preset, allowing you to balance the output from preset to preset for optimum results.

The Poly Level is not stored in presets, but set depending on the number voices of polyphony you have selected for the Solaris to play. This circuit sets the maximum amount of ‘headroom’ available for all voices, to ensure that clipping is kept to a minimum, but that you get the best levels for the polyphony required.

The Poly Level should be adjusted lower as the number of polyphonic voices increases. So, if you are set to use 1 voice, and then set the Poly Level at 127; if you select 4 voices, you probably want to adjust the level to

70 or so. The idea is to adjust it to the point just before clipping, or to where you feel is good for your system.

Since this is a variable unknown by any preset creators, this parameter is not stored in the Preset List.

MIDI Implementation

MIDI Clock

MIDI Clocks are derived from the incoming MIDI signal.

Most software sequencers provide a stream of MIDI

Clock ‘ticks’ along with the standard MIDI events. To use an external clock source of a software sequencer, you must fi rst switch the MIDI Clock control in the

Global page or Main Sequencer section. The Int Clock switch must be off to use external MIDI clocks.

There are 24 ‘ticks’ per quarter-note. Whenever you see the option to set rate or tempo by MIDI Clock, you will also get a popup list of different timing resolutions.

Expanding Solaris

This section supposes that you have access to RD modules from Zarg Music or Modular 2 from Creamware Audio (Sonic | Core). These modules are not included with Solaris.

The idea behind the Solaris semi-modular approach is to expand its standard features with modules available on the Creamware SFP platform in an easy to use structured design. The initial idea behind this ‘semi modular design’ fi rst appeared in the Zarg Music Red

Dwarf introduced October 2000 – hence the abbreviation of ‘ RD’ for the modules.

Expanding Solaris with Sonic Core


In order to use Modular II modules with Solaris, you need to use one of the following Modular Templates.

Modular Oscillators and Filters

The Oscs& Filters Template has the following control signal inputs: Freq, Shape, and Audio. When using this for oscillators, connect the Freq control to the Frequency input of the oscillator module. Connect the Shape signal to any pulse width or waveshape control. The

Audio signal is not used.

For fi lters, connect the Freq control signal to any cutoff mod input (usually CFm1 or Cfm2), and turn up the associated amount knob on the module. (Note that there is no key tracking with this module.) Connect the Audio signal to the In of the fi lter.

For both oscs and fi lters, connect the fi nal outputs to the Audio Out jack.

In the case of Solaris, it’s more fl exible to use the built-in

Modular Windows in the Modular Osc section, as these have

MIDI and Gate signals as well. You can use these Windows to build complete synthesizers inside the Modular Osc itself! Solaris also has these built-in to each of the four fi lter sections.

Modular Gated

The Gated template has the following control signal inputs: Gate and Tmod. For envelopes, connect the Gate to the Gate input of the module, and connect the Tmod signal to any Tmod input (Tmod1 or Tmod2), then turn up the associated amount knob. With these you can usually adjust things in a positive or negative direction, depending on the desired affect.

The Outputs are Control and Audio. Connect the Out of the envelope to the Control Output.

The Audio Output is only used for Drum Oscs in the current Red

Dwarf EX Gated Mod slots. This function may appear on other synths in future versions.

Using a Modular II Template

The Modular Templates are special, in that they have to be saved once you insert modules in them. There are two Modular templates, and each includes a preset list object for saving. The templates need to be saved, as they are “references of references”. Please refer to the section Saving Modular Patches.

You will defi nitely want to make separate copies of the

Modular Templates, each named specifi cally, so that you can have different sets of Modular modules ready for use.

Here’s what I recommend:

In the Pulsar fi le browser (or Windows Explorer), make a copy of the template object fi rst, then rename it to something that you are going to create with it (for example, to use the ‘ Modular Gated II’

Template to load the Drum Osc module, fi rst duplicate it and rename it ‘Drum Osc’ instead of ‘ Modular

Gated II’).

When you load it into the synth, open the template’s

Modular Window by double-clicking on the slot (if it is not already open), and drag in and connect the desired modules ( Modular 2 Drum Osc module in this case, connecting gate in to gate, and audio out to out).

Then right click over the RD Module’s name in the

Insert Slot, Select ‘Surfaces’, then ‘Open Preset

List’ to open it (or use the small disk icon in the upper right corner of the Modular Window), and then save the Device. Now you will fi nd that the Modular

Gated II Template that you made and renamed as

‘Drum Osc’ will always have the Modular 2 Drum

Osc in it.

MOST IMPORTANT: To save presets using these templates, you must fi rst save a populated template, then remove it from the RD slot, fi nally reloading it again into the RD Slot before creating presets.


Expanding Solaris with RD Modules


The RD concept provides a basic ‘synthesizer shell’, into which the same variety of oscillators, fi lters, and effects modules as mentioned above can be put together by the user, within certain structural limitations. The fi rst device in the series (called Red Dwarf EX), is basically taken from the successful CombPlus Pro design. Using the modulation and signal routing from that device as the basic ‘shell’, the user can insert any two sound sources and any two fi lters in the SLOTS provided to create a ‘custom’ design. Even more important, EACH preset can be contain different modules for these slots, as well as for the effects, providing for a much more fl exible device. It’s even possible to obtain some unusual routings, such as placing an oscillator block into a fi lter slot, using the oscillator slots as sources of

modulation, etc., or for the ultimate in fl exibility, use a

Modular insert to ‘drop in’ your own custom confi guration of oscillators or fi lters, using the Modular 1 or 2 modules.


For editing, you will want to double-click on the name of the module once you’ve loaded it in a slot. This brings up a ‘mini’ control panel, which contains all parameters that could not be accounted for on the main synthesizer front panel. (The ‘mini’ control panel should appear when the module is fi rst loaded in the RD Slot.

Double-clicking on the Insert Slot should put away the panel; repeated clicking should toggle the display of the panel.) A few modules do not have a control panel.

For these, there is a special “Offset Module”, which you can then use to change the frequency of an oscillator or fi lter. You fi rst load the Offset Module, then load the desired module into the Offset’s insert slot.

Each module will have different parameters, although there are similarities in the dual osc pairs, etc. Since all oscillators need an initial frequency, and most all of them need some waveshape control (except the dedicated sine or saws), these parameters have been located on the main synth surface. Special ‘oscillator pairs’ have provisions for offsetting the initial pitch or shape settings, and also, one of the two oscs usually have a switch that shuts off waveshape modulation completely.

Likewise for the fi lter slots, all fi lters have a cutoff

(frequency) parameter, so you adjust this via the main synth surface. Most fi lters also have a resonance control, but this parameter has been put on the individual

‘mini’ control panels for each fi lter. If you double-click on the inserted fi lter module and get nothing, then there is no control surface needed for that module (for example, the 18 dB Lowpass has no resonance, so no control panel).

You will need to adjust the main synth’s controls and the ‘mini’ control panel settings together to get the most out of the oscillator pairs. Just be aware that the main coarse and fi ne tuning controls interact with the mini control panel settings, as do the Initial Shape and

Shape Mod controls on the synth’s main panel.

Special note to RD II users:

Unfortunately, there is a permanent bug in the graphic object that displays the number of points and values for the Key

Level with the new preset list. This means that sometimes the graphic will correctly represent that which was programmed for the preset, but other times the display will not be correct, even though the Key Level output is correct. And then there is the chance that the fi rst time you select the preset, you will not get what was stored, and only upon selecting the preset again, or going to a completely diff erent preset and back again, will you get the desired result. What this means is that it is practically impossible to make dependable preset settings with the new style preset list and the Key Level object, however the old style list (available from the Modular Oscs section) will store them correctly.

The Rotor II, Rotor with Mixers, Y connector II, and Series-Parallel II no longer need to be saved as templates

(see below), unless you are doing something like fi lling the Y connector with other Y connector modules. In this case, you should make specifi cally named copies of the

Y connector modules for this kind of ‘stacking’. (Please follow the instructions to make copies of the modules in the Templates section below.)

The two special case modules - the Y Connector, and the Series/Parallel - allow you to greatly expand the capabilities of the different slots. These can be placed in slots to expand the number of objects available within a slot. For example, you may want to have four oscillators in a single slot. By using the Y Connector, you can drop in two ‘oscillator pair’ modules, one for each insert slot in the Y Connector. The only thing you should be aware of is the level; it’s easy to clip audio levels when using this approach.

And, as already mentioned, you can also use these special modules within themselves, i.e., you can insert a second and third Y Connector into both Y Connector slots, etc., which I have called ‘stacking’.

Saving Modular Patches

Using the Modular Windows - when trying to make presets using modules from any of the Modular series,

I found that there was no way to store the ‘patch’ in the new preset list, so, I had to insert one of the older

44 | EXPANDING SOLARIS preset list modules to accomplish this. You will fi nd the list by selecting the button labeled ‘ Modular Presets’ in the Modular section.

To properly save the modules and preset settings requires a special process:

• load the desired modules into the Modular Windows.

open the (older style) Preset List with the preset icon on the Modular panel (below the Show button for Modular 1).

on the old style Preset List, click on the Device icon

(small fl oppy disk below the word, “Device”), which will bring up the message, “Are you sure you want to save this device? The preset changes you have made will affect the device in other projects which include it.” press Yes, and the Solaris device will be saved with the desired Modular modules in place (note - you must do this to save the loaded modules, but this will also overwrite the Solaris device where you have it (so, you might want to make a backup of a

‘plain’ Solaris somewhere). The device will grow in size as you add Modular modules.

list. In general, it is easier (and probably better) to use the RD slots and the Modular Templates, as this allows use of the new style preset list, without having to deal with the older style preset list.

Some XTC users report that they cannot use the “show” button to display the Modular patch window; I have not seen this problem, but apparently there is something in their set-up that does not allow Modular 2 patches to be displayed in XTC mode.

Figure 55: Saving a Modular Preset

Likewise, if you load samples in the Wav Oscillator slots, and then happen to Save the Device for the

Modulars, you will store the Solaris with the samples in it. To avoid this, clear the Wav Oscs before saving the device.

Now you can create presets using the older style

Modular preset list. To store a preset with the older style Preset List, click on the small disk icon below and to the right of the red X below the word, “Preset”. This will save all parameters currently in the Solaris, including the new style Preset List.

Storing a preset here will also store EVERYTHING in the Solaris, so you could use this as a master preset list. It’s just much slower, as it will store every single parameter inside the

Solaris, even unnecessary ones (ones not needed for the particular sound event). It also has the problem that a new style preset list will be called when an old style preset is selected, so if you’ve made any edits to your main preset list, you should save it before selecting any presets from the old style preset
