I guess this is the part where I speak up and add that I'm one of the few
people in the world who ∗really, really∗ likes the external signal
processor on the MS-20 (and finds its' pitch->CV converter perfectly
adequate for tracking a bass guitar). Which has both a gate output and
LED's to indicate A) input signal clipping/peaking, and B) gate status.
For a MOTM Envelope Follower, I would really like to see those functions
with a Trigger output in addition to the Gate, where a trigger signal would
be generated every time a gate starts AND every time the input signal
amplitude has a positive-going crossing of the trigger threshold level,
which is set by a front panel knob whose 'zero' level is determined by the
gate threshold level knob. Even better would be an additional hysteresis
knob that would set a threshold level above the gate threshold, but below
the trigger threshold, so that re-triggers would only occur if the input
signal amplitude had passed below the hysteresis threshold before
re-crossing the trigger threshold.
Hmm ... so with all that, we'd need knobs at least for:
1) Input amplitude (preamp)
2) Gate On (rise) threshold level
3) Gate Off (fall) threshold level (must be < Gate On level unless there's
also a setting for Gate hysteresis)
4) Re-Trigger threshold level (must be > Gate Off level)
5) Re-Trigger hysteresis level (must be > Gate On level, < Re-Trigger
threshold level)
Plus one or two LED's ...

Does that work for you? (or, more importantly, does it make sense to you?)
