LeafAudio - VCO-1

VCO-1 (v1.4) is a purely analogue VCO for the modular Eurorack system. It can complemented by EXP-1 Expander module to add many functions like Sync, lin. FM, Wave Morphing, LFO etc. VCO-1 is temperature stable and provides a clean 1V/oct tracking over minimum 4 octaves. VCO-1 and EXP-1 are a powerful combination of modules with lots of instant fun! High quality parts, switches, pots and knobs, good feeling and big enough for comfortable everyday work, no fiddly controls. Check out the module on Modular Grid. https://www.modulargrid.net/e/leafaudio-vco-1

Check buttons below for a build video about VCO-1 and EXP-1 by Synth DIY guy. Very nice to watch before you build it, specially for beginners. And make sure to check the Soundcloud audio demos - they're good!

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

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

After finishing it, the 1V/oct tracking has to be adjusted, what might need some experience.
