Permanently circuit-bent keyboard (YAMAHA PSR-185)

HOW IT HAPPENED:
I was playing around with the inside of this keyboard for the second time, but my brother was with me this time.

I had just been messing with the sound chip before, but there was a big chip inside which was very hot (some kind of main processor?), which we couldn't resist probing with wires. Anyway, the result was very worrying - I thought I had permanently broken it at first. The display just did some crazy crap when you turned it on. But after a few hours of no power it returned to working state - well, ALMOST working, like this. ;)

The sounds in the sound chip are stored next to each other one after the other, and we seem to have PERMANENTLY overwritten the positions in the chip which it thinks some sounds start at, so we get insane bits of random different sounds coming out together. (I'm lucky it even does ANYTHING. XD)

The headphone output is connected to Line Input on my computer, that's why it's easier to hear than my my previous circuit-bending video.
