SAFETY INSTRUCTIONS Please read carefully before using: • Only use the correct power adaptor - 230V (or 115V whatever your country needs) • Never handle the adaptor with wet hands • Never excessivly bend the adaptor cable or get it trapped or place heavy objects on it. If the adaptor cable becomes damaged, replace the adaptor. • Ensure the unit is disconnected from the mains before moving or cleaning. • Always disconnect the unit from the mains if there is lightning in your area.
About The Manual This manual will explain all details about each module, along with some standard and more complex patching examples. With modular synths there are a near limitless range of patching possibilities. We can’t possibly tell you all the different patches possible, so if you need further help and information there are many great resources on the web. The manual is constantly being updated with new patching ideas and other information, so there will never be a final version.

AS0084 84HP Minimodular Case Module Power Connectors: 9x Doepfer, 3x Integrator Power input: 12-15V AC external power supply 500mA or higher, 2.1mm DC socket. 230v mains adaptor only supplied for Euro models. 115V US adaptors are available from Noisebug. Width: 84HP Introduction This is a lower cost alternative to the pricey aluminium style cases. The AS0084 will take any combination of Concussor, A100 or Integrator modules with no problems of gaps or lining up because it does not use tapped strips.
Handling and Inserting Modules Modules can be placed in any position in the rack. It is a good idea to place one module in at a time and test it before going onto the next. This way if any module causes a problem, it can quickly be identified. Some modules contain static sensitive circuitry . This circuitry is exposed when not fitted into the rack. When handling any module, try and only handle it by the front panel. Try not to touch any part of the circuitry.
Power socket as used by Doepfer. The red stripe on the cable indicates pin 1 (-12V). You may think of pin 1 as being at the top, but Doepfer have place it at the bottom, so Doepfer sockets appear UP SIDE DOWN! Each power line (+12, -12, & +5) has 2 pairs of pins. The Ground (GND) line uses 2 pairs. Note: With Doepfer systems, +5 power is an option. Some Concussor modules require +5, so check you have this option installed! With Concussor power supplys, +5 is always supplied as standard.
AS1600 6U Rackmount case Fitting Modules The modules are fitted into place using No.4 2.9mm diameter, 10mm long self tap screws. When using a mounting hole for the first time, firm pressure must be applied when turning the screw for about the first turn to tap a thread into the steel. Excessive force is not necessary, but a good fitting cross-head type screwdriver should be used and a firm grip. Once a thread has been broken, the screw should screw in fairly easily.

VCO 6HP - Voltage Controller Oscillator Introduction VCO is a single VCO laid out in a similar way to the VCO section you would find on a monosynth. The VCO can go down to low frequencies so they can be used as an LFO. Voltage Controlled Oscillators (VCOs) in general The VCO or signal generator, commonly found on most music synthesizers consist of an exponential amplifier, a resetable integrator and waveshaping circuitry.
VCO - Voltage Controller Oscillator Introduction VCO is a single VCO laid out in a similar way to the VCO section you would find on a monosynth. VCO includes a glide (slew) function, so this is a great bonus. The VCO can go down to low frequencies so they can be used as an LFO. Voltage Controlled Oscillators (VCOs) in general The VCO or signal generator, commonly found on most music synthesizers consist of an exponential amplifier, a resetable integrator and waveshaping circuitry.
General Specification Inputs CV PW SYNC Outputs SAW SQUARE Controls Tune Glide Pulse Width Saw Level Square Level Size 12HP Power +/-12V, GND using Doepfer power socket. Our modules do not support Doepfer's buss system. Therefore do not expect the module to react from buss signals.
VCO-RM - Ring Modulation / VCO Introduction VCO-RM is a single VCO-RM laid out in a similar way to the VCO section you would find on a monosynth. VCORM includes a glide (slew) function, so this is a great bonus. VCO-RM can go down to low frequencies so they can be used as an LFO It also has a complete and independent Ring Modulator. This can be used on its own, or you can patch the oscillator into the RM, and along with another audio source gives you great Ring Mod’d sounds.

VCO-SUB - Voltage Controller Oscillator Introduction VCO is a single VCO laid out in a similar way to the VCO section you would find on a monosynth. VCO includes a glide (slew) function, so this is a great bonus. The VCO can go down to low frequencies so they can be used as an LFO. Controls In Detail Tune The VCO has a wide ranging tune control. Turning Tune alters the basic pitch of the oscillator.
General Specification Inputs CV PW SYNC Outputs SAW SQUARE SUB1 SUB2 SUB3 Controls Tune Glide Pulse Width Saw Level Square Level Size 12HP Power 5V, +/-12V, GND using Doepfer power socket. If the Sub appears not to work, it is probably because your Doepfer case does not have 5V. This module requires 5V. Our modules do not support Doepfer's buss system. Therefore do not expect the module to react from buss signals.
VCO Calibration It is fairly easy to tune in the VCO to another sound as you just have to alter the front panel VCO Tune control. There may be instances though were the octave spacing (scaling is out). The VCO could go out of tune as you play up the keyboard. As mentioned earlier, this does not neccessarily mean the VCO itself is at fault. The VCO responds to 1V per octave, it could be the control source is not giving out exactly 1V per Octave. With most control sources the output scaling can be altered.

It allows triggering of a range of analogue devices; drum voice modules, envelope modules, analogue sequencers, analogue drum machines, and anything else with a gate, trigger or clock input.
Uses Triggering Drum Voices The most logical use for the MT16 is for easy programming of Concussor drum voice modules via a MIDI sequncer. Electronic percussion patterns can be quickly created using for example Cubase’s grid editor or a rhythm sequencer such as the Akai MPC2000. Gating Envelopes The length of the trigger pulses is determined by how long the MIDI key is held down for (sustained). When you hold a MIDI key down, the trigger output will stay on (+5V) until the key is released.
MCV - MIDI to CV Converter Introduction The MCV is a quick and easy to use module that allows control of analogue devices from a MIDI controller. Use Connecting Connect the MIDI sequencer or other MIDI device to the MIDI input of the M2CV. Normally CV1 (PITCH) goes to the pitch CV input of your synth. CV2 goes to any other CV input, like filter cut-off CV. Gate goes to the Gate or Trigger input o your synth.
M2CV - MIDI to CV Converter Introduction The M2CV is a quick and easy to use module that allows control of analogue devices from a MIDI controller. The M2CV is straight forward MIDI to CV conversion - easy to use. Use Connecting Connect the MIDI sequencer or other MIDI device to the MIDI input of the M2CV.

SQ8 8 Step CV and Gate Sequencer Inputs: Reset In Clock In Outputs: Power Supply: CV +/-12V, +5V, GND using Gate Integrator or Doepfer Step 1 power sockets.
Controls In Detail – standard operation Clock In The SQ8 requires a +5V clock signal. Each clock signal will advance the sequencer 1 step. When the last step is reached, it resets back to the first step. Take the clock signal from a square wave LFO, Clock module or MIDI to Clock converter. Clock Thru The clock signal appearing at the CLOCK IN socket is buffered and transferred to the CLOCK THRU socket, so it can be daisy chained to another sequencer.
Alternative Applications Of Controls: Clock In The sequencer does not have to be stepped through at normal regular intervals as is usual. It can be clocked from any source, such as the gate from a MIDI-CV converter or monosynth, the trigger out of a drum machine such as the TR606/808, or from the gate outputs of other analogue sequencers. This allows it to step through the sequencer rhythmically, as and when you want.
More SQ8 Example Patching Standard connection to a monosynth to control pitch and gate; CV out to Synth CV in. Clock Thru to Synth Gate in. Filter control of monosynth; CV out to Filter cut-off input. Connect CV and Gate of synth to another sequencer or MIDI to CV converter. Alternative connections to a monosynth; Plug CV out to Synth CV in Step 1 out to Gate in The synth will be triggered on the 1st step.

Controls In Detail – standard operation. Clock In The GT8 requires a +5V clock signal. Each clock signal will advance the sequencer 1 step. When the last step is reached, it resets back to the first step. Take the clock signal from an LFO, Clock module or MIDI to Clock converter. Step Outs There are 8 step out sockets. As each step 1 to 8 is reached, the corresponding step out socket will go high (output +5V).
More GT8 Example Patching Any step out is a divide by 8 clock divider. Take step 1 (or any other step output) into the clock of another sequencer. GT8 controlling open and closed hihats (or 2 monosynths); Gate out 1 to CH, Gate out 2 to OH. Use a pulse shaper on the clock input of the GT8 to change the Gate output pulse widths. Take different step outputs (from same or other GT8 sequencers) and mix them with a multiple to get another gate sequencer.
