This is true, however it does work if the lag has already arrived at the
last note. So this would only create a "glitch" if you play three notes
quicker than the lag time.
If I remember correctly, this is also the case with the SH-101 -- it looks
that way from the schematics (that it simply switches to the output of the
lag circuit), but I don't have my SH-101 assembled to test it.
This is not the case with the Mini Moog. Even if you set a very long glide
time, play a new note, then switch on the glide, it has no effect. Glide
only works if you turn it on before the beginning of the new note. Of
course, the Mini Moog does not have keyed portamento. You can play a note
with the glide switched off, leave the studio, come back, switch the glide
on, hit another note, and it will still glide.
Does anyone have a schematic??

Very clever!!

This is true.

The bypass switch already works with a control voltage, it's just that the
Bypass LED can give a false reading with certain voltages, and the output
exhibits the above mentioned "glitch" which Larry just explained. Of
course, the first problem is entirely Paul's fault for adding all these
extra LED's to the MOTM system :)
Yeah, I know, I'm supposed to play the 820 with a footswitch. Who am I,
Rick Wakeman?? :)
So what the heck is an OMS-820??
