Filter ICs and crossfade circuits

hehehehe, anyone heard/seen of the prophet VS?
I started to design this, uses 6 VCA's... My idea was a panel with four 
sockets for input one for output, two CV and a joystick, I also intended to 
include a sin+cos LFO, so you could feed these into the X/Y and have it 
rotating through the inputs, kinda like a LisaJou (sp?) figure, but with 
audio...
I stopped when I got my uController kit to make my poly midi>cv convertor 
(which, BTW, is going quite well so far)
