MOTM

On diy today, Grant Richter mentioned having found a little way to diy CV 
outs (not simple I gather). I've heard this device mentioned here before, and 
being one who is interested in nontraditional controllers I might be 
interested in something like this. Unfortunately, I don't know that much 
about it. Can anybody tell me more about the specifics (like price for 
example)? Offlist would probably be better. I'd appreciate it.

Thanks!

Can't believe how quiet the list has been!
