PATCH Mogger Ring Modulator

Moogerfooger Ring Modulator emulation. See

Stereo Ring modulator effect.

The MF-102 Ring Modulator is a direct descendant of the original Moog modular synthesizers. It contains three complete modular functions: a ring modulator, an
oscillator, and a dual-waveform LFO.



Amount of processed signal. Sets the ratio of dry (signal as input) to wet (effected) signal.


Randomizes all the parameters.

LFO Section


Determines how fast the LFO oscillates. The knob spans the frequency range of 0.1 Hz to 25 Hz. Can be linked to the synthesizer's LFO. (see Ring Modulator's settings)


Determines the amount of LFO waveform that frequency modulates the carrier oscillator. When the knob is counterclockwise, there is no frequency modulation by the LFO. When the knob is fully clockwise, the carrier oscillator is frequency-modulated over a range of three octaves.

Square-sine waveform

Switch selects either the square waveform or the sine-like waveform that the LFO produces. The square wave produces trill effects, whereas the sine waveform produces vibrato and siren effects.

Modulation Section


The frequency knob and the LO-HI switch determine the frequency of the carrier oscillator. The frequency knob has two calibration ranges: 0.6 Hz to 80 Hz, and 30 Hz to 4 kHz. The LO-HI switch setting determines which range is on.

The oscillator can have sine or square wave, or a combination of the two with the sine-square fader.


You can add drive to the input signal with to type of wave-shaper, from subtle crunch to hard distortion.


Adjusts the phase between left and right LFOs to increase the stereo effect. At minimum, LFOs modulate in phase, at maximum, LFOs are out of phase.
