Eventide Harmonizer H90 - RingMod

RingMod
Ring Modulator is an effect created by multiplying an input signal by an audio frequency waveform; the
result is a waveform containing the sums and differences of those frequencies and their partials. This
creates a waveform with complex (and usually nonharmonic) bell-like overtones. By using the Speed Mod
control to modulate this carrier frequency you can create useful and interesting sounds.
Intensity: Effect level.
Type:
Ring
String
Pitch
Pitch: If Type is set to Pitch, RingMod will pitch track the incoming audio and modulate it by a
waveform that is shifted up to +/- 1200 c from your input, giving you a consistent synth-like tone
across all notes. This parameter is unused when Type is set to Ring or String.
Speed / Sensitivity: Sets the modulation sweep rate. Speed becomes Sensitivity when Shape is set
to Envelope or ADSR.
Shape: Selects the waveform, or source, of the modulation. The choices are:
Sine
Triangle
Peak
Random
Square
Ramp
SampHold
Envelope: The modulation becomes driven by the amplitude of the audio input.
ADSR: The modulation becomes driven by an ADSR triggered by the amplitude of the audio
input.
Manual: When selected, the Manual Mod parameter will control the modulation.
Tone: Rolls off the high frequencies as it is turned clockwise.
Depth Mod: Slightly detunes the right and left voices, which creates a stereo field.
Speed Mod: Controls the amount of modulation of the Speed parameter. Analogous to FM
(Frequency Modulation).
Mod Rate / Mod Sens: Sets the secondary LFO rate – determines how fast the Depth Mod and
Speed Mod “wiggle” their targets. Ranges from 1/8th to 8x the Speed value. Mod Rate becomes
Mod Sens when Mod Source is set to Envelope or ADSR.
Mod Source: Selects the secondary LFO waveform, or source. The choices are:
Sine
