These are modules that I have designed and built for my own modular synth. If you'd like to build one information about board availablility is HERE

8 Channel Quantizer PIC based Quantizer module with 8 independent channels. VC over scale selection and Hold/S&H

Quantizer LCD display board An alternative way of displaying scale information for the 8 Channel Quantizer

VC Resonant Low Pass Gate A version of the Buchla Low Pass Gate. This module includes Voltage Control of the Mode and Filter Resonance amount.

Quad Exponential/Linear VCA Quad VCA module based on the Gallo/Irwin circuit for the SSM2164 (V2164). Switchable response between Linear and Exponential

Orgone Accumulator for 4U A Complex Oscillator designed by Jim Matheson in a PCB set for 4U systems

VC Equal Power Panner Based on That Corporation application notes for the THAT2180 chip, this is a single channel crossfader featuring switchable center attenuation. Can be wired as a crossfader, panner or switchable between the two

Transistor Ladder Filter -A Mini Moog style filter. The circuit is adapted to modern modular standards by Yves Usson. My board run is approved by Yves

VC Timer A multifunction module: Variable Gate to Trigger and Gate Delay. Also functions as a VCO and SR Flip Flop

4U Mounting Bracket Mount 4U boards to the front panel with no panel drilling required

4U Loudest Warning format boat 16GA steel enclosure for mounting individual 4U modules

Fractal Gain Sequencer -In Development Waveshaper module. Divides waveform into 8 bands and controls gain of each band. Fractal multiplication of waveform. Can modulate a second waveform
