Well, i bought the ASM pcb to Gene Stopp around 1998 and built it right away but the VCF had given me some trouble. So after a few years, i got back to work.
I’ve added some features to it :
1 Moog ladder VCF
1 Korg MS-20 VCF
Octave switch on each VCO
Waveshapers for each VCO with Sine / Saw / Tri / Square waveforms
Two LFO’s with Sine / Tri / Square waveforms
1 Ring Modulator
1 Sample & Hold
1 Envelope Follower (finally I got rid of it)
1 Midi to CV converter
1 Power Supply
