I think somebody on the list already mentioned that one of the "classic"
MS-20 tricks (I've used it plenty of times) is feeding back the audio
output (from the headphone jack) to the LPF modulation input while the
filter is self-oscillating.  (and if that is audio going into the Fc mod
input of a self-oscillating '420, that's AMAZING tracking - once again,
hats off to Paul!)
