Interesting. Pitch tracking is difficult, because there’s never really a guarantee that the loudest harmonic is the fundamental. Even guitar can briefly have a harmonic that’s stronger that the actual note, and octave pedal will bounce up and down by an octave until the harmonics settle down.

> Thanks Sean, I think I know what you mean. I once built a pitch-following synth that used a similar method (4046 PLL) and it’s tracking was rather unpredictable. Still, it used to glitch in interesting ways. Some of the models I mentioned used a chip VCO to control the clock rate, so perhaps a CV interface might be doable.

>> About the Boss 'sampler', I had an RSD-10 and while it could do the things it said on the box there were a lot of limitations in terms of expected input ranges. From memory the controls didn't work in some modes and getting any consistent tracking was hard. They have a bit of a cult status that is not really deserved IMO.
