WERKSTATT-Ø1

The Moog Werkstatt-Ø1 is a patchable,

100% analog synthesizer whose design is based on classic Moog circuits.

Assembly is extremely simple: Any user can quickly build this analog synthesizer with minimal tools and expertise. Through assembly and inspired investigation, the

Werkstatt-Ø1 is an excellent platform for exploring the world of analog synthesizer circuits. A lifetime of experimentation, knob twisting, and sound design awaits.

ANALOG SYNTHESIZER BASICS

An analog synthesizer generates two types of signals: Audio Signals and

Control Signals. Audio signals are the sounds you hear emanating from the sound creation circuits of an instrument. Control signals, on the other hand, are used to change and/or modify the settings of these circuits. Due to the analog nature of the instrument, these Control signals carry a continuously variable voltage level. These signals are referred to as Control Voltages, and most analog synthesizer components are “Voltage Controlled.” An additional type of control signal is known as a Gate, or Trigger, which is simply used to initiate an event. Changing Pitch or frequency is an example of using a Control Voltage; playing a key on a keyboard is an example of generating a Gate signal.

In an analog synthesizer, each set of circuits performs a particular job. The oscillators, filters, and envelopes, etc. are each self-contained modules.

By design, these modules are wired together using both audio signals and control signals. However, patch points and patch cables can allow these modules to be reconnected in new ways. This is the basis for the term

Modular Synthesizer. The first Moog synthesizers were modular synthesizers.

In this diagram of the Werkstatt modules, the solid lines represent audio signals, and the dotted lines represent control signals. The definitions and functions of each module are described in the Werkstatt Features and

Controls section.

ASSEMBLY

Putting together your Werkstatt is easy. No soldering is required, and all of the electronic components have been pre-assembled. The only tools you will need are a #1 Phillips [ + ] screwdriver, and a good pair of scissors. And while assembly is not complicated, it is important to follow each step, in order. Be mindful that you are working with electronics, so a good measure of caution and care is always in order.

A NOTE ABOUT ELECTROSTATIC DISCHARGE:

You may have noticed that little electric shock you sometimes receive when you touch something like a metal doorknob. This is called electrostatic discharge, and it can be harmful to electronic components. To protect the circuitry when you are assembling your Werkstatt, leave the circuit board in its protective anti-static sleeve until you are ready to install it. Also, take a moment to ground yourself by touching a metal surface or grounded object before you handle the circuit board.

PARTS LIST

Unpack your Werkstatt synthesizer kit and make sure all parts are present and accounted for before you get started.

INSTRUCTIONS

1) ATTACHING THE FEET

Attach the four rubber feet by pushing them into the holes of the Bottom

Chassis and twisting.

2) TRIMMING THE NYLON WASHER

The black nylon washer is used as a spacer between the audio jack and the inside of the Bottom

Chassis. You will need to cut a 1/16” section from the washer.

9

3) INSTALLING THE ELECTRONICS

A) Carefully remove the Printed Circuit Board from the protective sleeve.

Take the washer you prepared in the previous step and slide it onto the audio output jack, lining up the missing section with the metal tab on the jack.

B) Place the Printed Circuit Board into the Bottom Chassis. Slide the audio jack through the jack hole, and be sure the five mounting holes in the

Printed Circuit Board line up with the standoffs on the Bottom Chassis.

Using the silver pan head machine screws (x5), loosely attach the Printed

Circuit Board to the chassis. Take a moment to make sure everything is lined up neatly and correctly—including the power input jack—and then go ahead and tighten the screws.

Finally, place the black nylon hex nut on the audio jack, and hand-tighten the nut to hold the jack securely to the Bottom Chassis.

4) POWER / LED TEST

Using only the included power supply, connect the barrel end to the power supply input of your Werkstatt; connect the other end to an AC wall outlet (100-240

Volts AC / 50-60 Hz). At this point, the red LED on the front panel (LFO) should begin blinking. If it does, you’re ready to move on.

NOTE: Unplug the power supply from the Werkstatt before proceeding.

5) ATTACHING KEYBOARD BUTTONS

Place the 13 button caps on the keyboard buttons.

6) ADDING THE TOP PANEL

Place the Top Panel in position so that all of the knobs, switches, and keyboard buttons pass through the corresponding holes.

Secure the Top Panel using the four (x4) black sheet metal screws. The screw holes in the Top Panel should line up with the screw holes in the Bottom Chassis.

NOTE: Tightening these screws may require a little extra effort the first time, as these screws must cut threads into the metal holes.

YOUR WERKSTATT IS NOW COMPLETE.

11

FEATURES AND CONTROLS

The Werkstatt is a monophonic (one note a time) analog synthesizer, and as with many analog synthesizers, the Werkstatt is modular in nature. While there are many hard-wired connections that allow the Werkstatt to be used as-is, the addition of a Patchable Header allows the freedom to connect the modules in new and creative ways.

DEFAULT SETTINGS

Carefully set all of the controls to the default positions shown below. This will provide a great starting point for exploring the functions and features of the

Werkstatt-Ø1 Analog Synthesizer.

12

VCO

(VOLTAGE CONTROLLED OSCILLATOR)

The Oscillator is the primary sound generating component of an analog synthesizer. Based on the same circuitry as the Minimoog Voyager and Little Phatty, the Werkstatt oscillator produces a raw waveform that is rich in harmonics.

While the keyboard determines the note being played, the frequency knob determines the pitch of that note.

The keyboard determines the note played based on the setting of the

Freq control - these two control inputs are summed together.

FREQ (FREQUENCY KNOB)

The Frequency knob offers a wide pitch range, extending over nine octaves.

Keep in mind, the pitch is also controlled via the keyboard, and can be modified by other control signals. Depending on your monitoring system—and your ears—the outer ranges of the FREQ knob may appear to be inaudible.

WAVE (WAVEFORM SWITCH)

Two waveform options are available on the Werkstatt. Each waveform, or waveshape, carries a distinct harmonic content, creating a different sonic signature, known as timbre.

SAW: Short for Sawtooth, the Saw wave looks similar to the cutting edge of a saw blade. The Saw wave contains both even and odd numbered harmonics, and creates a bright and buzzy sound before filtering. The strength—or level—of each harmonic is the reciprocal of its number in the harmonic series.

PULSE: This waveform is unique in that it only contains the odd numbered harmonics. The ratio that controls the relative volume of these harmonics is determined by the Pulse Width. The width of the pulse can be anything from a wide rectangle to a square to a very narrow rectangle. The thinner the wave, the more the upper harmonics are accentuated.

PWM (PULSE WIDTH MODULATION)

When the Pulse waveform is selected, the Pulse Width Modulation knob can be used to determine the shape of the Pulse, thereby changing the timbre of the wave. With the knob set just a little left of center, the wave will be square, with a 50% duty cycle. The duty cycle is commonly thought of as the positive portion of the wave. The range of this knob can create a narrow pulse wave with a duty-cycle of almost zero, all the way up to a wide rectangular wave having about a 95% duty-cycle.

NOTE: This knob will not function when the VCO MOD DEST switch is set to

PWM. In this case, the Pulse Width will be controlled by the VCO MOD SOURCE.

13

VCF

(VOLTAGE CONTROLLED FILTER)

The Werkstatt uses the classic 24dB per octave Moog Ladder filter. This low-pass

Voltage Controlled Filter (VCF) selectively shapes the timbre of the sound created by the oscillator, by attenuating and/or emphasizing certain harmonic elements.

CUTOFF (CUTOFF FREQUENCY KNOB)

The Cutoff knob specifies the frequency where the Filter is applied. Turning the knob to the right will open the filter, allowing more harmonic content to be heard, creating a brighter sound. Turning the knob to the left will close the filter, causing more harmonic content to be filtered, creating a darker sound.

RES (RESONANCE KNOB)

Directing the output of the filter back to the input allows the Moog filter to create a harmonic boost at the cutoff frequency. The amount of this boost, or emphasis, is controlled by the Resonance knob. By increasing the Resonance and decreasing the cutoff, the Werkstatt filter can be made to self-oscillate, creating a sine wave that can be used as second audio sound source.

VCA

(VOLTAGE CONTROLLED AMPLIFIER)

This section controls the output level of the

Werkstatt. As you may have noticed, there is no Volume knob on the Werkstatt. The VCA boosts the final audio signal to a suitable level.

MODE (MODE SWITCH)

The VCA can function in one of two ways, controlled by the Mode switch.

ON: In this position, the VCA is always on, and the audio signal of the

Werkstatt is output continuously, all the time. This setting is great for when you are creating synthesizer sounds and effects that need to play for an extended period, or droning sounds.

EG: EG is short for Envelope Generator. When the switch is in this position, the VCA is controlled by the Attack, Sustain, and Decay characteristics of the Envelope Generator Module.

14

VCO MOD

(MODULATION OF THE VOLTAGE CONTROLLED OSCILLATOR)

Modulation is a way of introducing subtle or drastic changes to a sound—or anything in between. In order to use modulation effectively, you will need to select a modulation source, choose a destination, and control the depth of the effect.

SOURCE (SOURCE SWITCH)

This switch allows you to choose which Modulation Source will be applied to the Oscillator.

EG: EG is short for Envelope Generator. When the switch is in this position, the Attack, Sustain, and Decay characteristics of the Envelope Generator will be used as the modulation source.

LFO: LFO is short for Low Frequency Oscillator. The LFO produces a cyclic change that can be used to create a repeating effect. When the switch is in this position, the LFO will be used as the modulation source.

AMOUNT (AMOUNT KNOB)

Once a modulation source has been selected, the Amount knob can be used to control the depth of the modulation effect.

DEST (DESTINATION SWITCH)

This switch allows you to choose which control will be affected by the chosen

Modulation Source.

PWM: When the switch is in this position, the Modulation source will be used to continually vary the width of the Pulse wave. The VCO Wave switch must be set to Pulse.

NOTE: Placing the switch in the PWM position will override the Pulse Width

Modulation (PWM) knob in the VCO section.

FREQ: When the switch is in this position, the Modulation source will be used to continually vary the pitch of the Oscillator. This can be used to create a gentle vibrato or wild swoops in pitch, all depending on the Amount

Knob and the setting of the LFO Rate knob (or EG).

15

VCF MOD

(MODULATION OF THE VOLTAGE CONTROLLED FILTER)

Filter Modulation changes the value of the Filter’s Cutoff Frequency. Either the EG or the LFO can be used as a Filter modulation source. When the EG is chosen as the modulation source, the polarity of the EG can be reversed for even greater sound creation options.

SOURCE (SOURCE SWITCH)

This switch allows you to choose which Modulation Source will be applied to the filter.

EG: EG is short for Envelope Generator. When the switch is in this position, the Attack, Sustain, and Decay characteristics of the Envelope Generator will be used as the modulation source.

LFO: LFO is short for Low Frequency Oscillator. The LFO produces a cyclic change that can be used to create a repeating effect. When the switch is in this position, the LFO will be used as the modulation source.

AMOUNT (AMOUNT KNOB)

Once a modulation source has been selected, the Amount knob can be used to control the depth of the modulation effect.

POLARITY (POLARITY SWITCH)

The Polarity of the VCF modulation source can be reversed. That is, the normally negative portions will become positive, and vice-versa. For example, instead of using the Attack portion of the EG to boost the Filter Cutoff frequency, inverting the polarity will allow the Attack portion to lower the Filter Cutoff

Frequency. Just be aware that if the Cutoff is already set low, inverting the EG polarity might close the Filter too far, making it appear as if the Werkstatt is not creating any sound.

[ + ]: Positive is the normal polarity for the VCF Modulation Source.

[ – ]: The negative position reverses the VCF Modulation Source.

16

LFO MOD

(LOW FREQUENCY OSCILLATOR)

The Low Frequency Oscillator creates a consistent modulation source that can be used to add a repeating, cyclical change to any of the modulation sources.

It can be used to modulate the Filter Cutoff Frequency, the Pitch of the Oscillator, or the Width of a Pulse wave. Using the Patchable Header, you can also use the LFO to modulate other parameters, such as the VCA output level. The

Werkstatt LFO has an upper frequency of around 600 Hz—well within the audio range. This ability allows the LFO to create rich and unusual sounds when modulating the Oscillator pitch or other destinations.

RATE (RATE KNOB)

The speed, or frequency, of the LFO is controlled via this knob. The red LED will flash once for every wave cycle, providing visual feedback of the LFO speed.

WAVE (WAVE SWITCH)

This switch allows you to select the Waveform of the LFO.

SQUARE: When the Square wave is selected, the LFO will alternate between two distinct values representing the upper and lower limits of the wave.

Some good examples of Square wave modulation are the emulation of an acoustic instrument playing a trill, or many vintage video game sounds.

TRIANGLE: The Triangle wave creates a continuously changing value that sweeps between the upper and lower limits of the wave. Vibrato is a good example of Triangle wave modulation.

17

ENVELOPE

(ENVELOPE GENERATOR)

Each time a key is pressed or a trigger received, the Envelope Generator can produce a series of control voltages that allow you to change the value of certain parameters over time. The Attack, Sustain, and Decay parameters combine to create an Envelope shape that can be chosen as a modulation source.

SUSTAIN (SUSTAIN SWITCH)

In a simple sense, the Sustain switch allows you to choose either a piano-like behavior, or something more like an organ, by activating the Sustain segment of the Envelope Generator.

ON: When the Sustain switch is set to On, the Envelope will continue to sustain as long as the keyboard key is being played. In this mode, the Werkstatt behaves more like an organ.

OFF: The Off position bypasses the sustain segment of the envelope generator. The Envelope will advance directly from the Attack stage to the Decay stage. In this mode, the Werkstatt creates more of a plucked sound, like a piano.

NOTE: With the SUSTAIN switch in the OFF position, the attack must be very short or the EG will not produce an output.

ATTACK (ATTACK KNOB)

The time it takes for the Envelope Generator to reach its maximum level is known as the Attack time. For a fast Attack, turn this knob counter-clockwise.

For a slower Attack, increase the value by turning the knob clockwise.

NOTE: Keep this knob turned down when the SUSTAIN switch in the OFF position, or the EG will not produce an output.

DECAY (DECAY KNOB)

The time it takes for the Envelope Generator to reach its lowest level after the key is released, or after the attack segment is complete is known as the Decay time. For a fast Decay, turn this knob counter-clockwise. For a slower Decay, increase the value by turning the knob clockwise.

18

KBD

(KEYBOARD)

The Werkstatt is equipped with a one-octave, C to C keyboard. The keyboard features round buttons as opposed to traditional keys, but the layout is the same. The keyboard operates with a low note priority; if more than one note is played at the same time, the lowest note will sound.

This diagram shows how the “button” keyboard of the Werkstatt (above) relates to a standard piano keyboard. Although the note names shown are correct for this layout, the actual note being produced will also depend on many factors, including the VCO FREQ knob, etc...

KEYBOARD OCTAVE SCALING

Play the lowest note [ C ] on the keyboard; now play the highest note [ C1 ]. The interval you hear between these notes should be one octave. If you have an electronic guitar tuner, you can use it to verify the notes being played. If the interval is not one octave, there is a Variable Resistor trimmer [ VR10 ] on the Printed Circuit Board labeled KB TRIM that can be adjusted to fine-tune the keyboard octave setting.

GLIDE (GLIDE KNOB)

To achieve a smooth pitch transition from one note to another, increase the

Glide amount. Turning the knob clockwise increases the amount of time required to glide from one note to another. Turning the knob counter-clockwise will cancel the glide effect.

19

PATCH

(PATCHABLE HEADER)

Unlike fully modular analog synthesizers that have patch points on every module, the Werkstatt has gathered these inputs and outputs into a single compact Patchable Header.

The physical format is different, but the function is the same. The Patchable Header allows control signals generated by the Werkstatt to be easily routed to the control inputs of the VCO, VCF, VCA, and

LFO, vastly expanding the sound creation possibilities of the synthesizer. The five patch wires included with the Werkstatt are designed to make the most of these patch points. In addition to control signal inputs, the Patchable Header also features an audio input that feeds directly into the Filter.

BEST PRACTICES

In general, the Werkstatt is designed so there are no “illegal” patches, though not all make musical sense. In experimenting with the Patchable

Header, there are some ground rules/best practices that apply.

It is common to create a “Y” connection at a CV out point and drive two separate inputs. Many of the Werkstatt’s outputs already have two connections. However, it is best to avoid mixing two Control signals by creating a

“Y” connection at a CV input, as adding these voltages together can possibly exceed the capabilities of the input.

You should also avoid patching an output to an output; this is another version of passive voltage summing that can lead to unpredictable results. Patching an input to an input is not likely to result in any useful response.

Note that there are control outputs for both the VCO and VCF signals. Technically, these are audio outputs; these audio outputs can serve double duty as control signals. For example, the VCO output can be used for audio rate modulation, or it can go down to 8 Hz—low enough to use as a LFO.

PATCHING WITH OTHER ANALOG INSTRUMENTS

The Patchable Header was not designed to connect with external CV gear, but it is possible. For more information and cautions, please refer to the Interfacing with Other Synthesizers and Effects section of this manual.

20

REAR PANEL

The Werkstatt’s rear panel features two connection points; one audio output, and one power jack.

AUDIO OUTPUT

The Werkstatt’s single audio output features a 1/4” unbalanced (TS) jack.

POWER INPUT

Use only the DC power supply that was provided to power your Werkstatt.

Plug the connector end into the Werkstatt, and plug the other end into a compatible wall outlet.

ABOVE AND BEYOND

For some, the Werkstatt is simply a starting point for exploring new sonic possibilities. It is possible to modify the internal circuitry, and to interface with other music-making devices. Here are a few guidelines to get you started.

INTERFACING WITH OTHER SYNTHESIZERS AND EFFECTS

COMMON GROUND

The Patchable Header wasn’t specifically designed to connect with external CV gear, but it is possible to do so. If a CV connection between an external piece of CV gear and the Werkstatt is desired, the two devices must share a common ground connection or the external control will not work. The simplest way to achieve this is to plug the two devices into the same audio mixer. Both devices will have ground at the sleeve of their audio jacks. Make this audio / ground connection before connecting the units together.

USE CAUTION

Patching to external CV and Audio sources can subject the Werkstatt to voltages and currents that are beyond what it was designed to withstand. Caution should be exercised when selecting gear that will connect to the Werkstatt. Verify that the equipment used to provide a common ground connection is not faulty. Refer to the Specifications section for acceptable voltages.

CALIBRATING THE WERKSTATT FOR 1 VOLT PER OCTAVE

The VCO EXP IN connection point on the Patchable Header can be set to receive 1 Volt per Octave control signals. This calibration is performed using the Variable Resistor trim pot [ VR5 ] labelled VCO EXP

TRIM. It is located on the Printed Circuit Board, below and to the right of the VCO Pitch potentiometer.

21

To calibrate, play the lowest note on the keyboard, and set the VCO FREQ knob to the center position. Send a 0V signal to the VCO EXP IN patch point and measure the frequency of the VCO. You can use an instrument tuner for this function. Next, send a +3V signal to the VCO EXP IN patch point. Adjust VR5 to eight times the first frequency measurement (this equals 3 Octaves). Repeat this process to verify calibration accuracy.

Note that on the Patchable

Header, the KB CV is output as about 0.3 Volts/semitone, which is equivalent to about 3.6 Volts/Octave.

This allows the use of the

Keyboard as a wider range controller than if it were output as 1 Volt/Octave.

CREATING CABLES

For internal patching use the included Patchable Header cables. If you want to patch the Werkstatt to external gear, you may want to convert the included patch cables so they can plug into the 1/4” (3.5mm) patch points on the other products. One simple technique is to take a 1/4” TS patch cable and cut it in half to make two half cables. Now take one of the

Werkstatt patch cables and cut it in half as well. Since the ground is being provided by the audio output, you would only need to splice and solder the inner conductors of the two half-cables together, and then insulate the splice with electrical tape or heat-shrink tubing.

22

STUDYING THE WERKSTATT’S ANALOG CIRCUITS

The Werkstatt circuitry was designed to invite exploration and study of its analog circuits. The complete schematic for the Werkstatt Printed Circuit Board can be downloaded from the Moog Music Website: www.moogmusic.com/werkstatt.

Test Points, Jumpers, and a mini 16 x 6 Experimenter’s pad are provided on the Werkstatt Printed Circuit Board. Although the Printed Circuit Board was created using Surface Mount Design, these features use plated through-hole construction to make measuring and experimenting easier.
