Nord Micro Modular
There's a Nord Micro Modular in the mix at the computer music workstation! Getting this thing to work is easy, using it as a modular synthesizer is hard. Because capitalism. It takes 12V at .5 amps.
It is possible to run Windows 10 on a Raspberry Pi for free. The obsolete but "supported" Nord Modular patch editor runs on Windows. This means a dedicated patch editor could theoretically run on an RPi with a 1024x768 screen, as that is the maximum resolution of the Nord editor software.
It is also possible to build a custom MIDI interface using the UART pins on the Pi. This is required for programming the Nord via SysEx.
