Moog 904-A Eurorack clone by DEMO

Published on Aug 2, 2016 Roberto Raineri-Seith

"A 'quick and dirty' demo of the Moog 904-A clone for Eurorack that can be ordered as DIY-project on my website (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 904.A, and this post for another video.
