Non Linear Circuits 4Q72 & dual VCF

Published on Sep 15, 2013 cirtcele·95 videos

"This PCB contains a VC LFO which has sine & squre outputs and a range from 0.04Hz to 700Hz (with 10V CV).
The main circuit is a VCF based on the ARP 4072 (the weird one with the LM3900), I added a VC Q circuit to this which the original does not have."

"2 state variable VCFs on one PCB, based on std OTA design. Feature 1V/oct, VC Q and generally sounds good
:)"
