Description: A 12-dB/octave crossover drives low and high rotors. A toggle switch lets you change
speeds on the fly, at a selected acceleration determined by the inertia setting.
Notes: Crank up the drive control for a distorted sound (set the level and bandwidth to tame those
harmonics). The FM and AM controls set the amount of Doppler and tremolo to your liking, while two
stereo voices per rotor simulate microphone placement. This algo doubles as a two-speed, four-voice
ring modulator (set FM amounts to zero, AM amounts to 100%, and set slow and fast speeds to
somewhere in the audio range).
I/O Characteristics: Mono-in, stereo-out.
