Teensy CV input and output for eurorack modular synths.

You are using a simple Voltage divider for your -5V Offset Voltage, so every Noise on the negative Rail will bleed into your Circuit. How accurate are your A/D readings then?
 
I haven't tried connecting it to a pitch CV, and I don't have an oscilloscope, but the input is certainly stable enough to prototype ideas with. I find the input to drift +-4 values of the 12 bit input. This is also largely dependent on your power supply, I am using a 4ms Row Power 40. It was certainly stable enough for me to start trying things.
