[sdiy] What;s going on with that dsPIC ?

[cheater00 .]

I really like the case on that "victorian" synth. How did you make it?
Pretty cool!

Got some pics of the front panel? I wonder what parameters you went with.

Can you tell us a bit more about the architecture of the synth?

Also, what is the "sound card"? Is it part of the "victorian"?
