<p>hey! You've got so many cool ideas I don't even know where to start. I've been meaning to get back to you for a while to let you know how psyched I am about your ideas.<br />
As far as using the remaining OSC for routing the audio input. It's not an issue of how many Oscillators there are, it's an issue of how many volume control circuits there are. and there are 4, so in order to run the audio input through a volume control transistor bank, one would have to disconnect one of the 4 oscillators. </p>
<p>vactrols are the way to go for CV. you can do Lots of stuff with transistors as well, put a transistor in place of a pot and send current to the center pin. Ray wilson uses that to generate LFO pitch modulation on his schmitt trigger based WSG. There are lots of projects out there that use the 40106 schmitt oscillators. All the tricks they're doing for cross modulating and oscillator animation will work on the drone lab. Tom Bugs put a really cool power starve pot on his 40106 based post card weevil. It's just a 1m pot between power and the 40106 IC. lots of possibilities!
