@Chris that's awesome! What Pi you running? Is it running munt on it? How does it run? Also can you run other synths on it? I'd love to do something like this even though I own a MT-32 already!
@cee-S-dee, im using a Raspberry Pi 4 and it's just running the MT-32 Pi project files with no OS underneath it. According to the project it has General MIDI, Roland GS and Yamaha XG support, im currently only using the MT-32 / CM-32L support as I have a SC88-VL for the others.
It's not that difficult as it's all through hole soldering and all of the parts are readily available
