VCO-1 is a purely analogue VCO for Eurorack. Together with EXP-1, its expander module it is a complex oscillator with Sync, lin. FM, Wave Morphing (tri>saw / tri>pulse), LFO, additional Triangle out, internal routing possibilities etc. VCO-1 is temperature stable and provides a clean 1V/oct tracking over minimum 4 octaves, mostly even more. VCO-1 and EXP-1 are a powerful working horse with lots of instant fun! High quality parts, switches, pots and knobs, good feeling and big enough for comfortable everyday work, no fiddly controls.

Tuning (Coarse) ca. 20Hz - 20kHz
Tuning (Fine) ca. 8 half tones
Pulsewidthmodulation (PW)

1V/oct input for CV-controlled pitch
PWM input for CV-controlled pulsewidth
Pulse audio output
Saw audio output
