control the speed of the rotor and horn independently, adjust the mix of the two, and modulate the
speeds themselves, for interesting and dynamic effects.
Mix: Wet/Dry mix, where 100 is an all wet signal. It has a special nonlinear taper which puts most of
the knob travel in the most usable range.
Type: Select the size of the cabinets.
Standard
Giant
Rotor Spd: Sets the rotation speed of the Rotor (low frequency) speaker, from 0.10Hz to 20Hz.
Horn Spd: Sets the rotation speed of the Horn (high frequency) speaker, from 0.10Hz to 20Hz.
Rtr/Hrn Mix: Sets the balance between the Rotor level and Horn level.
Tone: Rolls off the high frequencies as it is turned clockwise.
Depth Mod: Controls the amount of modulation of the Depth parameter. Analogous to AM
(Amplitude Modulation).
Speed Mod: Controls the amount of modulation from the secondary LFO that is applied to the Rotor
Spd and Horn Spd parameters. 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 Rotor Spd value. Mod Rate becomes
Mod Sens when Mod Source is set to Envelope or ADSR.
Speed: Sets the modulation sweep rate.
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.
Performance Parameters
Retrigger: Retriggers the primary and secondary modulation LFOs to the beginning of their cycles. Useful
for re-syncing during playback, or creative effects.
