Works for me.

Next question, each CV input takes two op-amps. Do we use 8 dual op-amps, or 4 quad 
op-amps?

The will need to be two differnt BOMs for 10 volts systems and 5 volt systems.
Just a few resistor changes.

I still wish we could put a little noise chip on the CVS board so it could be a truely stand 
alone electronium. Are we sure there isn't a cheap I2C or SPI noise maker chip or 
something?
How about a cell phone ring tone chip? Or a video game noise chip? Maybe a frequency 
synthesizer with an SPI programming port?

Any ideas?
