@Sweelinck's link above directs to the same image as displayed...

things I'd point out - the chord organ might be difficult to source... the teensy 3.2 is very difficult to find (probably end of lifed)

and the instruo ceis is quite expensive - you might want to look at the befaco vc adsr & it couldt be a good alternative and is available as a kit (or pcb/panel set)

Weird, it linked to the old one when I tried it out earlier, I've got very spotty wifi right now that's probably why. Thanks for the reccomendation, I'd rather do a kit anyways and cheaper is always nice.
I've also found a near exact dupe of the chord organ but updated to the newer teensy, though im struggling to find it again so maybe i made it up in my head.
