ANALOGUE modular synthesizers
(no midi, no software, no microprocessors) PCBs and Modules LIST
Friday, 10 March 2017
This Envelope Follower PCB was developed for use in the cellF synth, it is based on the design in the Buchla Easel. Obviously it has a few changes; a gain pot rather than a hi/lo switch and a gate output. It is a wonderfully sensitive and expressive EF, that works nicely with regular microphones and guitars.
The 1/4" jack connects to the switch of the 3.5mm input jack, the outputs are pre-amp (20x gain), envelope and gate. The LED indicates when the gate is on.
