The VCDO is based around the Electruc Druic VCDO chip - the schematic is an adaptation of the datasheet schematic, with some minor modifications. The VCDO offers amazing features, like (from the chips datasheet):
- exponential frequency response with no exponential convertor - 3-10 octave note range from 8.18Hz to 8372Hz3 - main oscillator with 16 waveforms arranged as a wavetable - sub oscillator with 8 waveforms at four octaves - bitcrushing effect - glide/portamento - 8-bit, 62.5KHz sample output rate - easy interfacing to control voltage mixers
1.6 mm thick, double sided, green base material FR4-Standard TG 135-140 surface finish HASL part values are silkscreened
chip is available directly from Electric Druid or from vendors (BanzaiMusic) no parts, just the PCB - LW format panel is available
