This looks great.
With a pitch tracker functionality, it would be a perfect guy ;)
TBH, the only pitch-to-voltage converter I've seen that really behaved nicely was the 1970s Gentle Electric unit, which was also available as a (very coveted!) Serge module for a while. They're not common things; tracking pitch of anything that's not outputting a nice, well-behaved sine wave was not easy to do until more recent digital analysis components (like what one finds into the Electro-Harmonix "9" series synth pedals) emerged in recent years. As an example, there's the F-V converter on the Korg MS-20...inaccurate and glitchy, but then those glitches and inaccuracies proved to be musically useful (thanks, RDJ!); those are more like the "norm".
