INTRODUCTION

INTRODUCTION

Thank you for purchasing Molten for iPad. Molten is a powerful and intuitive tool for creating percussive sounds and rhythm sequences.

The step sequencer is one of the earliest and most used forms of controlling a musical synthesizer. A series of buttons or knobs are used to represent each note in a measure.

Physical limitations often restricted these devices to 16 buttons, or steps, each step being a 16 th

of a measure. Such rigid patterns of notes where laid out on a grid and sometimes chained together to form larger compositions.

With the advent of the electronic drum machine in the early 1980 ʼ s from manufacturers such as Roland (the TR series), Linn and Akai, the popularity of pattern based programming increased. The manipulation of synthetic drum sounds has formed the basis of popular music ever since. The 16 note grid has been widely used in popular common (4/4) time music.

But what if you could split those buttons in half or thirds? To make rhythms not tied to a rigid grid? With Molten you can. Molten permits you to divide time, to divide the grid into a sequence of notes that don ʼ t fall into a rigid pattern. This flexibility permits the composition of tuplet based rhythms outside of the common (4/4) time. Coupled with a powerful 8-track sample based synthesis engine, Molten is also a capable drum machine.

MOLTEN MAIN FEATURES

PATTERN SEQUENCER

PATTERN SEQUENCER

The sequencer is the core feature of Molten. It is designed to be a flexible pattern based rhythm step-sequencer. Unlike traditional step-sequencers that have a fixed step size of typically 16 or 32 steps, Molten has a dividable step size. This flexibility allows for the easy creation of tuplet-based rhythms. Likewise, many traditional step-sequencers have a fixed or box based time signature, usually 4/4. With Molten, the time signature is flexible. It is this combination that allows for the easy creation of rhythms often heard in musical genres that require time signatures other common time, 4/4.

The power of molten lies in its grid layout. Vertically you can see as many as 8 instrument parts running simultaneously. Horizontally you can have anywhere from 1 beat on a single page to 16 beats over 4 pages. Taken at face value this seems very similar to many traditional 16-step sequencers. However with Molten it is possible to divide any beat into as many as 9 pieces, and this is where things become interesting.

Here is a basic 4 beat pattern.

In Molten, using its default setting of 1 page with 4 beats divided into 4 pieces, it would look something like this.

12

PATTERN SEQUENCER

Molten allows for 4 pages, 4 beats per page. So it is easy to create extended patterns with beat variations like the one below.

In the example below there are tuplet fills on the last beat of each measure. Traditional

16-step sequencers have difficulty producing a pattern like this.

13

PATTERN SEQUENCER

With Molten, it ʼ s easy. A sextuplet or triplet is created by selecting the beat, pressing division, and turning the data wheel.

Molten ʼ s flexibility with pages, beats, and divisions of the beat allows for patterns beyond the traditional 16-step sequencer and music in common (4/4) time. Below is a pattern in 7/4.

This pattern is easily created in Molten using 2 pages: 4 beats on the first page, 3 beats on the second.

Notice that the coloured square inside the note represents the velocity value. The first four notes have a ramped velocity range starting high (redder) and finishing low (bluer).

The thin yellow line visible over the full height of the grid is the Song Position Line

(SPL). This line indicates the position in the pattern during playback and moves left to right.

14

PATTERN SEQUENCER

COMPOSING A PATTERN

Composing a pattern is a simple case of tapping the pattern grid.

1.

2.

3.

4.

To add a note, tap the grid cell where you want the note to be placed.

You can remove an unwanted note by tapping on an existing note.

To change a note ʼ s velocity value tap and hold the note, then slide your finger up and down across the note. The LCD Display will indicate the velocity value as it changes.

If you tap and hold a grid cell then slide your finger across the grid you can quickly add a row of notes. Any existing notes will be removed as you slide your finger over them.

Notes

It is possible to edit the pattern while the sequencer is playing.

Instrument, track effects and master effects parameters may also be adjusted while the pattern is playing.

There is a no undo feature.

NOTE ON OFF AND VELOCITY

Each note in the pattern sequencer is represented by a note-on and a note-off message. This determines the length or duration of the note. If you were playing a musical instrument, such as a piano keyboard, connected via a conventional MIDI cable to another sound source, the note-on message occurs when you first press the key down. At this point, sound playback begins. When you release your finger from the key, a note-off message is sent and playback begins to end. This determines the duration of the note.

In a sequencer such as a Molten, these two messages are automatically added when the note is inserted into the pattern grid.

The velocity of the note, how hard you hit the physical key on the keyboard, determines the loudness of the note. This intensity in adjustable in Molten (see above) and is shown as red for high values and blue for low values.

The note-off message is important as it is used to determine the envelope release time in the instrument. By adjusting the length of the release we can adjust how much of the instrument ʼ s sample is played.

PATTERN SEQUENCER

SAVING THE PATTERN

Molten does not use the concept of pattern memory or memory bank slots. Instead each pattern is a document that can we can load and save. The pattern that is presently being edited is called the current working pattern.

AUTOSAVE

When exiting Molten by pressing the iPad Home Button, the current working pattern is automatically saved. The next time Molten is launched this saved pattern is restored and made the current working pattern. This pattern is given the name “autosave”.

PATTERN SEQUENCER

CHANGING THE PATTERN LENGTH

The length of the pattern can be adjusted in the Settings Menu. The overall length of the pattern is determined by the number of grid pages and the number of quarter notes per page. This adds up to be the total length of the measure.

Molten has up to 4 pattern grid pages. To change the current page tap one of the [P1],

[P2], [P3], or [P4] buttons. The buttons dynamically appear with the length of the pattern, i.e. a 3 page pattern would only show 3 page buttons.

Each page may have between 1 and 4 quarter notes.

The Settings Menu is used to adjust the pattern length.

1.

2.

3.

4.

To change the number of pages, tap the [SETTINGS] button.

The number of pages can be adjusted by tapping one of the buttons [1] to [4].

The length of each page can be adjusted by tapping the corresponding number of beats for each page.

To close the Settings Menu, tap outside of the menu.

Notes

If the pattern grid page already contains notes and the length of the page is reduced, notes will be removed from the end.

Likewise, if the pattern grid page is expanded, any previously removed notes will be lost.

CHANGING THE TIME SIGNATURE

In Molten it is possible to adjust the time signature of the pattern by adjusting the length of each page. In a single page pattern with a length of 4 quarter notes or beats, the time signature would be 4/4. By modifying the length of the page the time signature is changed, for example, 1/4, 2/4, 3/4, or 4/4. By adding a second page, the time signature is added together. Therefore by adjusting the length of the second page, and leaving the first page at 4, the time signature may become: 5/4, 6/4, 7/4, or 8/4 and so forth for each of the 4 pages to a maximum of 16/4.

20

PATTERN SEQUENCER

As each page is combined to form the overall time signature, it is possible to split the whole measure on the beat that feels the most logical to the performance. For example, a 6/4 measure may be made up of two pages of 3, or 1 page of 4 plus one page of 2, or any combination thereof.

1.

2.

3.

4.

To change the time signature, tap the [SETTINGS] menu.

The number of pages can be adjusted by tapping one of the buttons [1] to [4].

The length of each page can be adjusted by tapping the corresponding number of beats for each page.

To close the Settings Menu, tap outside of the menu.

LOOPING THE PATTERN

During the playback of the pattern, the sequencer will play through all of the pages in the pattern. At the end of the last page, it will loop back to the beginning. It is possible to adjust this behaviour by using the [LOOP] button.

1.

2.

3.

4.

To select the current page, tap the required page button [P1], [P2], [P3], [P4].

To loop only the current page, tap the [LOOP] button.

Tap [PLAY] to begin playback.

To loop the entire pattern, tap the [LOOP] button again.

During playback it is possible to change the current page. By utilising the [LOOP] button it is then possible to loop only within one of the pages. If the requested page to be looped is further along in the pattern sequence from where the current playback position is, the pattern will play through each page until it reaches the loop page. At the end of the loop page, it will then loop only that page.

21

PATTERN SEQUENCER

DIVIDING THE BEAT

In each of the pattern grid pages, Molten displays the length of the page as a sequence of rectangles. These represent the number of quarter notes in this page. The thin light coloured rectangle identifies the quarter note or beat. The smaller green rectangles underneath are the places where you can add an individual note. When the light coloured bar is orange it shows the selected region we are able to divide. By dividing the quarter note region we are able to form tuplet rhythms. This is shown in the diagram below. With 4 quarters notes, the first three are divided into 4 or sixteenth notes. The final quarter note is currently selected (orange) and divided into a tuplet of 3.

1.

2.

3.

4.

The highlighted beat follows from the location of the recently added or removed note, or…

Tap the quarter note bar region to move the highlight.

To divide the beat, tap the [DIVISION] button.

Adjust the number of divisions with the [DATA WHEEL].

The range of the division is 1 to 9.

SOUND SYNTHESIS

SOUND SYNTHESIS

The basic sound-generating unit in Molten is called an

instrument

. Each instrument is a sample based playback system for generating specific drum sounds, such as, bass drum, snare or cymbals. Coupled with the flexible synthesis and effect system, the sound can be transformed completely, allowing you to come up with unique percussion sounds.

There are a total of 8 instruments. Each of the 8 tracks is assigned an instrument. The parameters for each instrument are unique to that instrument. Unlike other drum machines you may be familiar with, Molten does not have the concept of a “kit”. Instead, the instrument for each track can be assigned any sound sample in any order, duplicated if required. We have included several commonly used default kit templates to help you get started.

The following diagram shows the arrangement of the sound synthesis system.

Each track effect consists of an amplitude modulation effect, a low-pass resonant filter, a 1-band parametric equalizer and a sample rate reduction effect.

25

SOUND SYNTHESIS

The TRACK MIXER controls the volume and pan of each track.

Each track is routed and combined within the STEREO MASTER EFFECT system that contains a feedback delay, reverb, 3-band equalizer and compressor.

THE INSTRUMENT

Each instrument consists of an oscillator and a final stage volume envelope.

4.

To access the instrument editor, tap the [INST/SEQ] button.

To audition the current instrument, tap the [TRIG] button.

It is possible to switch between instruments while the instrument editor page is active. Tap the [LED] in between the track volume knob and the instrument parameters.

Touching the TRACK MIXER controls on the left of the user interface will switch the instrument editor to that track.

OSCILLATOR

The oscillator is a monophonic sample player that supports time stretching.

SPEED

controls the time period at which the sample is played back.

PITCH

controls the pitch at which the sample is played.

WINDOW SIZE

controls the temporal resolution of the time-frequency analysis.

DURATION

controls the overall length of the sample.

SAMPLE

tap the sample button to load the waveform to be used by the oscillator.

Samples are categorised into two: factory samples and user samples. The name of the loaded sample file is shown in the TRACK MIXER. User samples may be deleted by swiping the far right area of the entry then pressing delete.

AUDIO PASTE

tap the AudioPaste icon to select an audio clip to paste into the oscillator.

26

SOUND SYNTHESIS

USER LOADABLE SAMPLES

Molten can read sound files that have been uploaded to the application via the iTunes

File Sharing process. Uploaded files appear in the User Samples section of the samples menu if they have a .wav file extension. The supported file format is: WAV, 44.1KHz,

16-bit little-endian, mono.

By using iTunes File Sharing it is possible to add, delete and modify the files that are included in the User Samples menu. The Factory Samples are those included along with the Molten application and cannot be changed.

ENVELOPE

The envelope is the final stage of the instrument signal and is used to control volume.

By modulating the amplifier or voltage controlled amplifier (VCA) stage, the sound can be given its basic shape.

ATTACK

controls how long it should take for the sound to reach full volume after the note-on has occurred.

DECAY

after the attack phase has finished, and the note-off has yet to occur, decay begins. During this phase the sound decreases in level until it reaches the Sustain level.

SUSTAIN

controls the level the sound will reach after the Decay phase. Once this has happened, the sound will stay steady at this volume until the note-off. Note that the

Sustain parameter is used to set a

level

, while Attack, Decay and Release are all used to set

times

.

RELEASE

controls how long it should take for the sound to decay to silence after the note-off.

27

TRACK EFFECTS

TRACK EFFECTS

The TRACK EFFECT system is available for all 8 tracks as an extension of the sound synthesis. The effects that are available for each track are:

Tremolo

1-band parametric EQ

Low-pass filter

Bit crusher

The order of the effect chain is TREMOLO, EQ, FILTER, and BITCRUSHER and cannot be re-ordered.

To access the track effects, tap the [INST/SEQ] button.

TREMOLO

The tremolo is essentially a volume control that is controlled by a low frequency oscillator. It is also known as an amplitude modulator.

FREQUENCY

controls the modulation frequency.

DEPTH

controls the modulation depth.

GAIN

controls the level of the effect.

BYPASS

controls whether the effect is active in the signal chain.

28

TRACK EFFECTS

PARAMETRIC EQ

With the 1-band parametric EQ you can boost or reduce a certain frequency band.

HZ

controls the centre frequency that will be affected by the EQ gain.

Q

controls the slope of the band.

GAIN

controls the EQ gain. If it is set to a negative value, the volume of the frequency centred on the HZ parameter is reduced.

MS

controls the interpolation time.

FILTER

The filter is in the style of a resonant low-pass voltage controlled filter (VCF).

CUTOFF

controls where in the signal the filter should start cutting. When set to a low value only the lowest harmonics (the bass) will pass through.

RES

controls the filter quality Q parameter. The resonance value controls how much the volume around the cut off frequencies are emphasised (louder).

GAIN

controls the overall level of the effect.

BYPASS

controls whether the effect is active in the signal chain.

29

TRACK EFFECTS

BITCRUSHER

The bit crusher is a sample rate reduction effect. It reduces the sample rate of the incoming signal using sample and hold. This adds a form of distortion to the sound recreating the characteristics of 8-bit and 12-bit hardware.

DEPTH

controls the amount of sample rate reduction.

SAMPLE RATE

controls the sample rate.

GAIN

controls the overall level of the effect.

BYPASS

controls whether the effect is active in the signal chain.

EXPANDED TRACK MIXER

The expanded track mixer controls the balance of the track in the overall mix. It duplicates the TRACK MIXER while adding a pan control.

VOLUME

controls the overall volume of the track.

PAN

controls the left / right stereo position.

M

mute or silence the track.

S

solo the track.

30

STEREO MASTER EFFECTS

STEREO MASTER EFFECTS

The stereo master effects system is a final stage effect processor that is applied before the final stereo main signal output. Output from each of the 8 tracks is fed into the master effects. The master effects are only available on the main outputs. You cannot use them on individual tracks.

The master effects include in this order DELAY, REVERB, EQ and COMRESSOR. The order of the effect chain cannot be re-ordered.

To access the track effects, tap the [INST/SEQ] button.

MASTER DELAY

The delay is a single-tap feedback delay with adjustable delay time. Some of its functionality can resemble tape loops, solid-state delays, and robotic flange style effects.

DELAY

controls the delay time.

FEEDBACK

controls the delay feedback amount.

GAIN

controls the overall level of the effect.

BYPASS

controls whether the effect is active in the signal chain.

Notes

The delay time is not tempo synced.

31

STEREO MASTER EFFECTS

MASTER REVERB

The reverb simulates the ambience of a room.

BRIGHTNESS

controls the brightness of the room. Low brightness gives the impression of a darker room by using a low pass filter, while maximum brightness leaves the reverb unfiltered.

ROOM SIZE

controls the dimensions of a simulated room. In larger spaces, the reverb is audible for a longer period of time.

DRY

controls the mix of the dry unprocessed signal.

WET

controls the mix of the wet processed signal

BYPASS

controls whether the effect is active in the signal chain.

MASTER EQ

The MASTER EQ is the final frequency-shaping tool. It is a 3-band equalizer.

LOW

is the boost/cut for the low (bass) band.

MID

is the boost/cut for the mid band.

HIGH

is the boost/cut for the high (treble) band.

GAIN

controls the overall level of the effect.

BYPASS

controls whether the effect is active in the signal chain.

32

STEREO MASTER EFFECTS

MASTER COMPRESSOR

The MASTER COMPRESSOR is a stereo dynamics processor designed to control the loudness of the final signal.

RATIO

controls the compression ratio; the ratio of the signal reduction when the threshold is exceeded.

THRESHOLD

controls the threshold level; signals above this threshold value are reduced in level.

ATTACK

determines the amount of time it takes for the compressor to react when the signal exceeds the threshold.

RELEASE

determines the amount of time it takes for the compressor to stop reducing the signal after the signal level falls below the threshold.

GAIN

sets the amount of gain applied to the output signal.

BYPASS

controls whether the effect is active in the signal chain.

33

SHARING YOUR PATTERNS

SHARING YOUR PATTERNS

With Molten you can share your patterns with others in three ways:

1.

2.

3.

Share the editable pattern file

Share the audio

Share the MIDI

THE PATTERN FILE

The pattern file is the application data file and it is given the “.molten” file extension. This file can be copied between users and their iPad ʼ s, allowing a different person from who created the pattern to edit and use the pattern. This is akin to sharing a document in a word processor.

The pattern file includes all the sequencer and instrument parameter settings. It also includes the name of the samples used in each instrument. Note that if the other person does not have the sample files, specifically any User Samples that may have been used in the pattern, then those instruments will sound blank. In other words, the pattern file does not include the sample files. Any sample files should be shared as well where the copyright permissions permit such sharing.

To share the pattern file, use iTunes File Sharing to copy the “.molten” files between the iPad and the computer.

EXPORT AUDIO

In addition to sharing the pattern file, Molten includes the ability to “bounce down” the audio to a WAV file. This process records the audio, as it would sound during normal playback to a WAV file. The WAV file can then be copied from the iPad using iTunes

File Sharing.

The exported audio includes the full effects system and can then be imported into another music application or digital audio workstation (DAW) of your choosing. Perhaps forming the basis of a larger song or track, and for additional mix processing.

Patterns exported in this way are named after the pattern file plus the tempo and an exported tag. For example, if the pattern was called “Dance Club” and had the tempo of

132 BPM, the exported file would be named:

“Dance Club-120bpm-exported.wav”

34

SHARING YOUR PATTERNS

To export the audio:

1.

2.

3.

4.

5.

6.

Tap the [SETTINGS] button.

On the toolbar at the top of the screen, tap [Export].

From the menu, tap the [Bounce Pattern] button.

If the sequencer is currently running, it will be stopped.

While the bounce is in progress, you will not be able to perform any other operation.

When the audio bounce is complete, an alert is shown informing you of the name of the saved audio file. Tap [OK] to continue.

Notes

The exported audio file format is: WAV, 44.1KHz, 16-bit little-endian, stereo.

MIDI FILE

Molten includes the ability to export the pattern grid as a traditional MIDI file. All of the note data from the full pattern grid is saved as regular note information. This also includes the note velocity values.

The MIDI file is a level 2 standard MIDI File, where each track in the pattern represents a key on the piano keyboard. The note naming follows the General MIDI standard drum map with the low C being the first track in the pattern, i.e. the one at the bottom of the screen nearest the transport controls. This is shown in the table below.

The exported MIDI file does not include the settings for the effects parameters. Being only the note data, it may then be imported into a digital audio workstation and used to rigger other sound sources, either as plug-ins or hardware modules.

35

SHARING YOUR PATTERNS

Files exported in this way are named after the pattern file and have the “.mid” file extension. For example, if the pattern were called “Dance Club”, the exported file would be named: “Dance Club.mid”

To export the MIDI file:

1.

2.

3.

4.

5.

Tap the [SETTINGS] button.

On the toolbar at the top of the screen, tap [Export].

From the menu, tap the [MIDI File] button.

While the export is in progress, you will not be able to perform any other operation.

When the export is complete, an alert is shown informing you of the name of the saved MIDI file. Tap [OK] to continue.

Notes

Unlike the audio bounce the sequencer is not interrupted while the MIDI file export is undertaken.

AUDIO COPY AND PASTE

Molten includes the ability to share audio between other applications installed on your iPad. This is achieved with Sonoma Wire Works AudioCopy & AudioPaste. The resulting copied audio includes the full pattern and effects, as though it were exported from the Export Audio option.

To copy the pattern ʼ s audio:

1.

2.
