MOTM

one change worth noting to the manual pushbutton gate-cum-LED mod 
http://www.users.qwest.net/~daveb2/images/MOTM-800_switchmod.gif  :

i combined both mods on a small daughterboard. the LED wasn't directly 
hooked up to the manual gate switch, they both were interfacing with the 
800 in different places.  and i wanted the LED to be as bright when the 
gate was triggered manually as with an external CV. so instead of feeding 
the LED opamps from the 800 OUT + or GATE jacks, i hooked this up to the 
junction of D3 and Q2. this way, the LED also sees when i've pushed the 
manual gate button (which is connected to the junction of D1 & Q1).

i used a momentary pushbutton which triggers the ADS stages when pushed and 
held, and skips to the Release stage when let go. so variable gate timings 
are possible by holding the button for varying lengths of time.

cheers
and thanks moe
