The 2hp VCA is a dual, linear VCA. It uses the renowned 2164 SSM architecture, giving it extremely low distortion and high quality audio outputs. With a CV input attenuator, and DC-coupled inputs this is your new go-to module for voltage controlled amplification of audio or CV.

Notes: The Buff Mult is a buffered multiple with LED indicators to show positive and negative voltages. Using wide bandwidth opamps, it functions as a dual 1-to-3 or a single 1-to-6 mult for audio, video, or CV signals.

Notes: The Listen Up is a small passive expander for the Listen modules that provides stereo 1/4" (6.35mm) jack inputs and outputs. It connects to one or two Listen modules and/or WAV Recorder module with the included 3-pin cables. There are four 1/4" jacks arranged in left/right pairs. The left jack of each pair can be used as a TRS stereo jack if the right jack is unpatched.

Notes: The RCD Breakout adds features to the Rotating Clock Divider module. Six switches allow you to set the maximum Divide-by amount, Gate or Trigger mode, Counting mode, Spread mode, and Auto-Reset. The RCD Breakout requires the RCD to function, and does not use any extra power.

Notes: The ACL Multi II is a 'multiple' module for connecting single audio or CV sources to multiple destinations. It has a wide variety of applications, such as precise synchronised control of multiple tone-generating VCO modules, simultaneous control of multiple VCF modules with a single envelope module, and many more creative modulation-related uses. All this is made possible because our multiple module actually contains two discrete modules - one passive and one active.

The non-buffered passive module lets you distribute one input signal to up to six freely interchangeable outputs. Some of the most rewarding uses of this are to send one CV control voltage input to six different modules, or distributing an audio source signal to several destinations. Of course, there are many more examples.

The buffered active module features two high-impedance inputs, one inverting and one non-inverting, and five low-impedance outputs. The main purpose of the active section is to stabilise the pitch of up to five VCO modules, but buffered input signal can be added, so the active multiple can be used as a subtractor too, allowing you to apply a modulator such as an LFO or a static CV source to change the pitch of them altogether.

The presence of inverting and non-inverting also has some fun modulation applications, as it's possible to subtract audio and/or CV signals from each other. For example, this could be used to subtract a filtered signal from the unfiltered one, thus inverting the filter's effect (i.e. turning a low-pass filter into a high-pass).

And though the active section is primarily designed with CV in mind, it can do some really creative stuff to audio waveforms too. For example, the inverting and non-inverting buffered inputs can function as a waveform mixer or subtractor, generating unusual results with audio signals and modulation signals alike.

Of course, while this module is designed with creativity in mind, we want stability too. To ensure our module reliably delivers minimal-error copies of the incoming signals, and thus that every melody and musical interval stays in tune, we use precision low-tolerance resistors and low-noise/low DC-drift/Offset Operational Amplifiers.

Notes: Following ADDAC System's T-Networks series, the importance of having the right input signal for firing drum modules or envelopes was realised. Gates and Triggers are often looked at as similar signals but at times it really makes a difference and results will change drastically depending if a Gate or a Trigger is fed to the input of such modules.

This led to the simple yet effective Gate to Trigger.
A four channel converter with bypass switch for each channel.

Any input Gate will be limited to a 1ms Trigger.

Notes: While ADDAC were working on the new VC Stompboxes several expression pedals were tested and it became clear that most often, while playing a modular system, your hands are busy.
It's also normal to have an expression pedal lying around somewhere, so ADDAC have brought these back, cleaned up the dust and put them to good use.
This module allows the connection of any standard expression and sustain pedal.

The expression pedal action can be fine-tuned with Range and Offset knobs.
Range defines the voltage range (-10v, +10v).
Offset transposes the range by (-5v, +5v).
Two leds, plus and minus, monitor the CV Output
Positive and inverted output jacks.
The sustain pedal action will generate a gate signal on the gate output.
One led monitors this output.
The module also features a bus board +5v Adaptor, this will be able to provide +5v to any bus board.
This feature can be removed through a jumper on the back of the module.

Notes: Take up to two CV signals and this passive module converts them to TRS outputs in order to control effects pedal modulation inputs, with attenuation on both channels. Simple, straightforward stuff.

Supplier's Notes:
ADDAC309 CV to Expression allows a simple and straight forward connection between modular and effect pedals that features expression pedal TRS inputs.

Instead of using an expression pedal into the effects pedal the user can use this module in between a CV source and the Effects pedal to be controlled.

This is a great way to control the available parameters on the effects pedals straight from a CV source.

ADDAC309 features 2 channels each with a CV Input with attenuator and a 1/4" jack output.

This is a passive module, the power needed for operation is taken from the pedal power instead of the modular frame, this allows for perfect matching of the pedal's operating voltage which can range from 3.3v to 9v.

Notes: The CVADDER-HQ is a precision adder especially for adding 1V/octave (pitch-controlling) CVs. This makes it possible e.g. to transpose a sequence. Compared to general purpose CV mixers (like POLAMIX), this module does the summing of the CVs very precise (within a few millivolts), so the desired pitch is not affected.

The module offers four CV inputs where three of them are summed, and the CV at the fourth input is subtracted - meaning "transposition downwards".

This module also allows transposing the incoming CV by one or two octaves or a variable offset by buttons.

A separate output provides the voltage of the internal transposition (+1, +2 octaves / free).

If the transposition buttons are not necessary and you prefer to have a dual precision adder, take a look at the 2CVADD-HQ module.

Notes: This module offers a four-quadrant-control for CVs via its joystick.

The module can act either as CV source at its four outputs, or as four-quadrant attenuator for the CV inputs. Beyond this, a mix of the input CVs according to the joystick position is provided separately.

Another feature is a gate output that is controlled by pressing the joystick handle.

The joystick remains in each position - there is no automatic "return to centre".

The JOYSTICK module can operate in two different modes:

Quadrants independent: In this mode, all outputs are zero when the joystick is in centre position
Overlapped: In this mode, each quadrant output fades from full to zero over the whole range to the opposite corner.

Together with a quad VCA / mixer (available soon from tangible waves) you can use the JOYSTICK also for mixing/blending four independent audio sources.
