i finished this one in august some time.. its a mini keyboard fitted into an old alarm clock i found. all i really remember about this is that i didnt like the first few schematics i came up with so i started over quite a few times. i also remember that i used an old dual audio amp for the filter and the AR generator. i think it was the 4565? yeah the 4565. it gave the AR generator some unexpected shapes but i liked it and kept it. i put a video up in September and it already has 5k hits! thanks to "matrixsynth","make", and others. thanks guys! but yeah, the keyboard is pretty awesome too. check out the schematic and the video demo for more info. heres some crappy pics i just took too.
