I made a rough-looking synth out of a raspberry pi and a trellis keypad, with heavy amounts of midi note automation. Added some drums and called it an album: https://bostjanzupancic.bandcamp.com/album/kaleidotoxin
This is not at all my typical musical endeavor. Let me know what you think, if you think anything, good or bad.
Cheers!
Cool sounds you've gotten out of a homemade synth. Super cool.
Rock on!
