I realized a little bit ago that I didn't know how the CS80 did the 
Sustain I/II trick. So, I've been looking through the schematics - and 
I'm still confused!  I only see the Sus I/II switch going to the SH 
board.  This explains the Sus I/II behavior of glide continuing after 
letting go of keys in Sus I but freezing pitch in the middle of a glide 
in Sus II (or is it the other way around??).  However, it doesn't 
explain how notes get cut off.  I thought I was onto something, but it 
was just the mixing of the Sustain slider on the left-hand panel (PN3) 
with the programed VCA and VCF release voltage going to the M cards.  
This circuit is on the Sub board.  Where did I get lost (which is easy 
to do on the giant schematic)?  I don't see the Sus I/II switch 
connecting anywhere else.

By the way, I wish the CS80 didn't freeze the glide in Sus II mode.  I 
think I might temporarily disconnect that wire to hear how it sounds 
with glides finishing in that mode.
