[sdiy] Roland/Boss "long chip" RDD63H101

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.

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.

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.
