[sdiy-interim] PLL (4046) for pitch tracking?

[Loscha]

Boss RPS-10,
has a pitch tracking input in the back for it's pitch shifter mode.
Uses the 4046.
Tracks quite well, has a good enough range to use of the majority of
the guitar's neck (the highs are filtered by the input stage, I
haven't opened it up, but, I imagine it would only get better as you
ascended into double digits of kilohertz.

 I get a bank of running an analogue Casio drum circuit through it,
and have the 4046 track that. Random psycho arpeggios. Magic.
