Eventide Harmonizer H90 - Page 177

Depth: Sets the modulation sweep range from narrow to wide. Controls the frequency offset of the
left and right channels to create a stereo image.
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.
Unused / Stereo Width: In mono, this control is not used. 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 waveform, or source. 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.
