Prototype MIDI-CV box for Novation Circuit
Published on Jan 2, 2016 Jason Hotchkiss
"A quick demo of sequencing analog gear using Novation Circuit and a compact MIDI-CV box I am working on. The gear used is a CB55 drum voice board (DR55 clone from circuitbenders.co.uk), Moog Minitaur, Pittsburgh Modular System 10.
The PCB shown here is a prototype, but I hope to have them on sale soon. It has a 3.5mm MIDI input jack so a simple stereo 3.5mm cable can connect it to Circuit's MIDI output. I've been working on bus powering it, but an external supply is used for this clip.
Support two mono channels with Note CV, Gate, Velocity CV (one for each Circuit synth track), and four drum gates (one for each Circuit drum track). Also an additional drum accent gate (when any
drum triggered at max MIDI velocity) which can double as a clock out.
Built around PIC16F1825 microcontroller with MCP4728 Quad 12-bit I2C DAC with on-board charge pump used to get full CV range.
I hope to have these on sale soon on my Tindie store https://www.tindie.com/stores/hotchk155/ ... watch this space
Cheers for watching!"
