Miniature VCS3 DIY synthesizer

video upload by Solx45

"Some years ago I made a mini (about half size) version of the EMS VCS3.
It's a great fun synth and it works. It has:

3 Oscillators, temp compensated with same outputs as the VCS3 and 1V/oct
Filter clone of VCS3 and 1V/oct
Ring Modulator
Noise generator
Simple envelope shaper with VCA
Output VCA
Digital delay
Joystick
10 x 10 patch matrix
Most electronics built onto 2 proto stripboards"
