Maybe a data entry knob for Poly 61?

I have been looking for a reason to learn PIC programming for a while. But, with my Matrix 1000 editor project, a PIC really does not have much contribute with compared to the LPC2103 ARM7.
However, a few nights ago I was thinking that it might be nice with a data entry knob on the Korg Poly 61, similar to the alpha dial on the alpha junos.
Perhaps a suitable job for a PIC?

Boys say go! (A simple cover)

I was bored this morning (night almost, woke up early) and was thinking of the Depeche Mode song "Boys say go" version performed at the Hammersmith Odeon in 1982. It's better than the album version (Speak and Spell).
Without giving it too much serious effort I decided to do a "remake" more than a cover of the song. I mean I wasn't trying to change it a lot. I wanted to modernize it slightly but still keep most of the sounds fairly similar to the original.

Polysix on the road to recovery

Don't underestimate the power of battery acid!

So, Christmas and New Year vacation is over. But, the day before I had to go back to work I made a last effort to get something done since I'd spent most of my vacation just playing computer games or doing nothing. I'd gotten the Poly 61 keys working and felt like the Polysix needed attention, so...

Poly 61 is "almost" working now

Dead keys
Normally you'd expect an old synthesizer to have problems, for example scratchy pots, dead voices, leaking batteries and dead keys.
Well, the Poly 61 was completely silent when I got it. It lit up and I could edit the presets and store them and everything, but there was just no sound anywhere. Also, I saw the leaking battery.
I was expecting a lot of hopeless searching for errors but I was pleasantly surprised...
