I put a demo video together introducing the Zoxnoxious analog synthesizer and showing how the software frontend, VCV Rack, interfaces to the headless Zero2 that runs the synthesizer. The synth is built from custom voice cards I design which are open source on github. The demo video introduces the project and describes the frontend (VCV Rack) components. I'm working on a second deep dive that goes into detail on the Pi's USB gadget setup of MIDI + the two Audio interfaces that do 27 channels each.

Using no OS and going bare metal with a microcontroller would be more typical for a project like this. But really I found the Pi's gadget mode, and thus pulling in Linux, to be ideal for the project. I didn't want to do low level USB coding. And I haven't found any libraries to achieve anything like the 54 channels of USB audio plus USB MIDI on other platforms. Pretty cool!
