Extreme abuse of the MOTM-480 CS-80 VCF:

www.synthtech.com/demo/rr_480demo.mp3

There are 2 "abuses" of the VCF:

a) the voltage-controlled resonance input is being modulated by a sine wave at *audio* rates
(generated by MOTM-300)
b) the BP Output is patched back to a VCF *input*. The feedback level is on a panel pot, and
manually tweaked.

The repeating sequence is an Encore UEG, driving 2 MOTM-300 VCOs. One is the "pitch", the other
is driving the resonance input at 1 octave higher. The LP Output then goes through a
'traditional' VCA (MOTM-190) enveloped by a basic AR shape (MOTM-800).

No other processing is used (reverb, filters, etc). All of the timbre is the result of
cross-modulation products in the MOTM-480, having the resonance "fight off" the driving signal,
and your basic overload/clipping :)

tag.
