Finally finished my tr-505, really glad how it turned out. It’s really a everlasting work in progress, but here are the bends so far:
-8 individual volume controls
-51 headerpins patchbay including synth sounds, sequencer glitches and drum rhytm glitches.
-6 patchable toggleswitches
-1 global pitchcontrol
-lcd spotlight and colourchanging led(not on the video)
I built it on a piece of perfboard painted black and only used pcb mounted parts to get as much bends in the least amount of space possible.
