Hi guys,

I have almost no prior experience with CPU's so I would like help with my project:).
I dissected the and intend to use it for my synth by translating the logic to a range of voltages and then control the synth by voltage per octave. Can someone explain to me what exactly is going on at the keyboard section? I have an idea but I can't really trust myself on this one. And how would I translate the keys to a range of voltages? Should I still use decoders?

Any help from more experienced people would be grand, be it a plan or some tips.

Cheers!

Edit: If I'm not mistaken notes are grouped (in 6) on to the same pin that leads to the decoder. This confuses me as to how polyphony works on this keyboard.
