From Fractal Audio Systems Wiki
The Ring Modulator is a double-sideband modulator that can be used to create harmonically unrelated tones from the input. The Axe-Fx Ring Modulator differs from the classic effect in that the frequency can be controlled by the pitch of the input.
- FREQ - Sets the frequency of the oscillator.
- FMULT - Sets the frequency multiplier for the oscillator. The actual oscillator frequency is the the FREQ value times the FMULT value.
- TRACK - When this is set to ON, the frequency of the oscillator tracks the input pitch. The actual frequency is then the pitch times the FMULT value.
- LOCUT - Sets the cutoff frequency of a lowpass filter on the output.
