4U006 - VCDO

voltage controlled digital oscillator

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

chip is available directly from Electric Druid or from vendors (BanzaiMusic)
no parts, just the PCB - LW format panel is available
