MicroController Control Voltage Thing
The MCCV thing is a simple microcontroller board based control voltage generator for analog modular synths. Rather than specific, fixed design, this project is a collection of materials for building your own.
The first one I built
This summer I agreed to play a live set for New York Modular Society]'s Patchable 017 show. I decided I wanted to interface some MIDI drum pads to my Serge modular. So, I built this:
- 4 control voltages out, 0 ~ +8V, ~2kHz max bandwidth
- 4 trigger outs, 0 ~ 8V
- Based on a Feather M0 board
- Optional display
- Programmable in C++ or Circuit Python
- I made it for Serge, but could easily be adapted for Eurorack.

What's here
This repo and wiki contain information so that you can make your own MCCV thing.
Workshop
In September of 2020, I'm leading virtual Workshop to make these. See the Workshop page for details.
Thanks
I could not have made this thing with the generous help of these others:
- Thea Flowers for careful explanations and her open hardware designs at Winterbloom
- Tom Whitwell for numerous pointers and tips, and his open hardware designs at Music Thing Modular
- denki oto, John Park, Tod Kurt, & CedarGrove for discussions, encouragement, and companionship on the (virtual) road
Of the many on-line resources I used along the way, two stand out:
- Adafruit - for not only making great parts to hack with, but having them all open source and open hardware, and putting the extra effort to host and foster an incredibly supportive, positive community of hackers.
- Mutable Instruments - for leading by example and showing that it is possible to produce beautifully designed electronic music instruments, and doing so with a long standing commitment to open source, open hardware, and community.
