Weird Patch of the Month (August 1997)

2. Triple feedback FM sound with cross-fading.

Do you have three unused VCF modules ,but no more VCO's?...Don't worry: we are going to use them to build pure sine waveforms from scratch...
Turn the Frequency cut-off point (Fc) of the two top VCF ,respectively to 9 o'clock and 10 o'clock, with the resonance (Q factor) fully clockwise. Now reduce the frequency cut-off point of the lower VCF (LFO) to a minimum (7 o'clock) and patch one output into an inverter: the complex FM sound should cross-fade, out of phase, between VCA1 and VCA2.
