Moog 904-A Eurorack clone by controlvoltage.org DEMO
Published on Aug 2, 2016 Roberto Raineri-Seith
"A 'quick and dirty' demo of the controlvoltage.org Moog 904-A clone for Eurorack that can be ordered as DIY-project on my website controlvoltage.org (production files only).
The filter is fed with a single square waveform from a Mos-Lab 921-B VCO.
Various settings, initially without, later with frequency control from the same envelope used on the VCA. No attenuators used. Delay and reverb added.
Final note: the module was only roughly calibrated and not all transistors were matched, so for purist there is some improvement margin left ;-)"
See this post from 2012 on the controlvoltage.org 904.A, and this post for another video.
