Hi Robert -

Yeah, I had trouble with this, too.  So here's the basic patch:

  * An LFO (a 320 in this case) SQR OUT to a MULT
  * MULT to GATE of a UEG and CV IN of the LPG
  * OUT of the UEG to 1v/OCT of a 300
  * SAW OUT of the 300 to IN of LPG
  * OUT of LPG to the console for recording

The patch is a UEG-driven 300 SAW into the LPG and NOTHING MORE.  
The LPG acts like a Low Pass filter with a built-in envelope.  Since 
the low pass-ness is created with a Vactrol, you get a spongy-boingy 
sound that's very characteristic. 

You can use other wave forms into the CV: SIN sounds cool and ramp 
(or SAW) is really trippy.  Also, if you have the vactrol CV going 
at a different rate from the UEG gate, more trippiness ensues.

Hope that helps.  It's really a cool-sounding tool!

Mike
