MOTM

Paul,
  There is one module I forgot to mention. There is a Serge
module called a UAP (?). Seems like a great Swiss Army knife.
It is basically an self retriggering AR. So it can be used
as an AR, a LFO, etc. By adjusting attack and release you
can get various waveforms. These may have been voltage
controllable. It has a trigger out when the release cycle 
ends so that it can retrigger itself. I believe it could
also be used as a VCO, when exact tracking wasn't required.
I can try to dig out a better description. Can any Serge users
on the list give more info.

It's not exactly a sexy module, but I remember Serge 
suggesting several of them in every system.

Sounds like one of those modules you never quite figure
out all the uses.
