System 80 810 Eurorack Synthesizer Voice Based On Vintage Roland Circuits

System 80’s 810 eurorack module has the full analog signal path for a synthesizer voice, the VCO, VCF and VCA. These are circuits from vintage Roland synthesizers with great sounding PWM on the VCO and the classic OTA 12/24db filter. Just add a sequencer or controller and a couple of envelopes and this module makes a complete synthesizer. We sequenced everything in this video with Malekko’s Varigate 4 and Voltage Block and added drums from Blck_Noir. 810 synth voice available here: https://w
