I don't know if anyone has already dicovered this, or if it's posted 
already or not, but I have found a nifty way to make a self-cycling 
A/D envelope generator out of an A-140 ADSR using a contstant 
voltasge source and a A-165 trigger modifier to wit:

Patch:

Output of A-140 ADSR into A-165 Trigger Modifier.

+/- out of the A-165 into RETRIGGER in of the A-140

Contant voltage source (held sequencer pot, held keyboard key 
or pot from A-176 Control Voltage Source into GATE input of 
A-140.

Kick-start/Set-up:

ADSR Sustain and Release to 0.

Constant voltage source to 0.  bring it up, it will reach a level that 
the A-140 will respond to as a trigger.  There you have it.  Your 
ADSR is now cycling, it's period and shape determined by the 
settings of the ATTACK and DECAY pots.

If you use a keyboard key  as the contant voltage, use the 
VOLTAGE out, not the TRIGGER OUT, you can possibly select 
one that generates a voltage lower than the ADSR will respond 
to as a trigger

You might have to dick with this set-up a little bit to get the 
oscillation to kick in, sometimes you even have to flip the RANGE 
switch a little, but you'll get there.  It works.

Have fun with your new LFO!
