I wanted another multi-part hardware synth, so I thought it would be fun to see what I could come up with using the parts I already had, particularly the touchscreen.
Loosely inspired by Norns, Brume is a four-part multi-timbral synthesizer that runs on a Raspberry Pi Compute Module 5. It has four synth engines and six voices per part, a shared filter section feeding an effects chain, a sandboxed Lua scripting layer, and a 10.1-inch touchscreen UI. A single USB cable presents the device to a host computer as a class-compliant audio and MIDI interface ala Elektron Overbridge.
Quick BoM to get started: cm5+carrier, any of the endless 10-inch hdmi touchscreens for RPI, and a midi controller. Novation Launch Control XL 3 and Korg nanoKONTROL2 are supported out-of-the box.
* While you can run this on a Raspberry Pi 5, Pi 5s don't expose USB OTG. The carrier board is what makes the class-compliant Audio+MIDI over USB work.

I hope this can be fun for others!
