drone/noise patch with FM
A drone/noise patch with 4 oscillators with FM, 3 filters and a wrapper.
The signal path is Oscillators 1-4 (Osc 1 can FM Osc 2, Osc 3 can FM Osc4) > Mixer > Filter 1 (usually Lowpass, but switchable) > Wrapper > Filter 2 (usually Highpass, but switchable) > Filter 3 (usually Highpass, but switchable) > Amp.
It’s a good idea to put a limiter behind these, since certain settings can create extreme noise and volume. Add some reverb, grain delay or your favorite effects as needed. NOTE: the controls on the waveform displays only control the view and do not alter the sounds.
Inspired in part by the Drone Lab hardware schematics from Casper Electronics (though clearly not an exact copy).
