Hi all,

I'm thinking of building a batch of filter/VCA PCBs. These are a 12dB/oct state variable filter design based on the 2164 chip (discussed here at length!). There's also an uncommitted VCA on the board, so it's a synth voice minus the oscillators and envelopes. Cutoff, Resonance, and VCA gain are all controlled by 0-3.3V CVs. The filter has lowpass, highpass, bandpass and notch outputs. The board runs on +/-15V or +/-12V supplies with no problems.

Cost is £50 for a complete tested module. They look like these:

If you're interested and would like more details, please contact me offlist.

Thanks,
Tom
