Eventide Harmonizer H90 - Page 188

When Effect Type is set to Opto, this controls the input’s slew rate (Edge) and, depending on the
input signal, may only have a subtle effect.
Type
Bias: Tube-inspired.
Opto:
Opto-coupled.
Depth: Sets the modulation sweep range from narrow to wide.
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.
Spread / Width:
Mono Out: In mono, this control spreads the tremolo and make the sound more smooth.
Stereo Out: In stereo, this control shifts the phase of the right channel’s LFO creating a tremolo
that will move from left to right in the stereo field. When set to Max, the right channel will be
180 degrees out of phase with the left creating an autopanner.
Depth Mod: Controls the amount of modulation of the Depth parameter. Analogous to AM
(Amplitude Modulation).
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 modulation source. The choices are:
Sine
Triangle
Peak
Random
Square
