That's pretty cool - and takes me back to my first DIY synth, back in
~1992.

I use an ARM3 processor as a University 3rd year project to build a
synthesizer. I had to make everything by hand - both hardware and
software (including complier, assembler, O/S, drivers).

The output was a simple 12-bit D-A chip, and its inputs were a built-in
88-key keyboard, a MIDI interface and an 8-bit A-D for sampling (all
mono).

Sounded absolutely crap though, but I got a degree out of it!
