Well, it's acutally something like the Sidstation I am going to build.

It wil just be an open project, where I will share my experince afterwards through a website, explaining everybody else how to take the SID chip out from a C-64 and make a live-oriented synth out of it

I have planned to put a lot of live controls on my SidSynth (nice name, or sucky?).

I have also thought about using 2 SID chips, just for the fun of it

You know, more envelopes, oscillators, filters, etc...

And, of course there will be MIDI on my SidSynth!
