Perhaps I just missed it, but I don't recall seeing an A-126 Voltage 
Controlled Frequency Shifter on your list.  This module can give you a 
lot of interesting modifications to external sounds.  Also, I was 
playing around with it last night, using the Quad LFO as an oscillator, 
and using the A-126 to change the overall oscillator pitch (modulated 
by an A-155 sequencer).
