midi2cv VS keyboardscanner

You can look at https://github.com/elkayem/midi2cv for a complete MIDI to CV implementation with Arduino and cheap DACs. Instead of (or in addition to) receiving MIDI, you'd also need to implement keyscanning and MIDI sending.

This project would be a great starting place, it's for a MIDI to CV circuit but it's got all the pieces in place for any random Arduino-based CV project, I'm adapting it to a Raspberry Pi Pico MIDI to CV module and it's working great so far

I spent some time creating a stripboard layout for Elkayem's excellent midi2cv project. Hopefully this saves someone else a couple of hours ;)

Midi-Cv converter project: https://github.com/elkayem/midi2cv

I can't read Japanese but translate works ok-ish on OPs linked page but it mentions: https://github.com/elkayem/midi2cv which is what I am basing mine on - or at least the majority of the hardware that's not the microcontroller.

Any reason not to build a MIDI to CV module? Having a MIDI in is pretty handy.

midi to cv

hello, electronic noob here. i was looking at the midi2cv module (https://github.com/elkayem/midi2cv) which uses two mcp4822, and this arduino based cv quantizer (https://youtu.be/op_DhPr2goc) which uses a mcp4726. My question is, can i use in both projects an mcp4725, (https://www.microchip.com/wwwproducts/en/MCP4725) since it has the same resolution and its the only available in my contry

My starting point for MIDI2CV will probably be this: https://github.com/elkayem/midi2cv - which does seem to have PB provisioned. The fun/creative/potentially frustrating part will be adding a dedicated breath CC channel and matching that up to a symbiotic ADSR/VCA unit.

This should help: https://github.com/oxesoft/keyboardscanner

In that case, check out https://github.com/oxesoft/keyboardscanner. You should be able to adapt the code to your specific matrix. I'd just suggest replacing the construction of serial messages by using the midi.h library, as it's a bit reinventing the wheel. You also don't need all those debugging conditions if you can simply view incoming midi messages from another device.
