[sdiy] FW: [Csnd] VCS3 GUI instrument

[Rude 66]

i don't remember offhand how it goes exactly, but the aks/vcs3 don't run on
1v/oct for one. on the aks, the keyboard/sequencer in connected with a
special cable, the one that also connects the wooden keyboards. i forgot if
there's actually anything you have to do with the pins. i can check this
week when i 'see' the aks again..
