So here's the A-106-1 demo I promised:
http://www.elanhickler.com/misc/analog_techno.mp3

-Analogue Systems VCO
-A-136 Waveshaper (used to shape the initial waveform)
-A-106-1 Xtreme Filter (highpass only)
-random voltage --> VCO Pitch Modulation in some cases.
-Recorded everything twice over, sometimes with different modulation
for a nice stereo sound.

-Digital synth percussion
-Software Compression
-Software Delay
-Software Reverb

I know there's a lot going on in there and it's not just an A-106-1,
but the sounds I'm getting in this demo with the filter cannot be
reproduced easily with another filter. I don't think I'd want to try
it with another filter. A-106-1 just has a nice set of features not
found on any other filter.
