and control. Whether used for manipulating samples or adding movement to strings, pads, guitars, and
keys, Undulator is a muse for creative musicians.
Intensity: Increase the dry/effect ratio.
Feedback: Controls the amount of feedback in the delay structure.
Depth: Sets the tremolo sweep range, which increases in depth and intensity as the knob is turned
clockwise.
Speed / Sensitivity: Sets the rate of the tremolo. 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: Controls the amount of detuning in the delay structure.
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.
