FXAlg #907: Ring Modulator
Algorithm Reference-127
Ring Modulator in ÒL*RÓ Mode
The other modulation mode is ÒOscÓ. In this mode, the algorithm inputs and outputs are stereo, and the carrier
signal for both channels is generated inside the algorithm.
Ring Modulator in ÒOscÓ Mode
The carrier signal is the sum of five oscillators. On all of the oscillators, level and frequency may be set. Four of the
oscillators are simple sine waves, while the fifth may be configured to one of a variety of wave shapes. Available
shapes are Sine, Saw+, Saw-, Pulse, Tri and Expon. Sine is simply another sine waveform. Tri produces a triangular
waveform, and Expon produces a waveform with narrow, sharp peaks which seems to rise exponentially from 0.
Pulse produces a series of square pulses where the pulse width can be adjusted with the ÒOsc1PlsWidÓ parameter.
When pulse width is 50%, the signal is a square wave. The ÒOsc1PlsWidÓ parameter is only active when the Pulse
waveform is selected. Saw+ and Saw- produce rising and falling sawtooth waveforms.
Smoothing is available to reduce the upper partials of the Pulse and Saw waveforms. The pulse wave, at 50% width,
turns into a sine wave when set to 100% smoothing. The sudden change in amplitude of a sawtooth turns into a
more gradual slope with smoothing, ending up as a triangle wave when set to 100% smoothing.
