MOD SOURCE Knob (A)

When Hot Hand, MIDI, or an expression pedal are not being used, the

Orbital Modulator features three different types of modulation control:

Envelope Follower, Sine Wave LFO, and Square Wave LFO. The MOD

SOURCE knob controls a gradual blend between them, so setting this

knob between two of the modulation graphics will create a sound with

elements of both modulation forms.

• Sine Wave LFO ( ): The sine wave LFO produces a very

smooth independently moving modulation. Use the sine wave

LFO for traditional ﬂanger, chorus, and phaser effects.

• Square Wave LFO ( ): Unlike the smooth modulation of a

sine wave, the square wave LFO has a blockish sound similar

to a sequencer. We recommend using a square wave LFO for

dramatic, choppy sounding tremolo effects.

• Envelope Followers ( / ): An envelope follower responds

to the amplitude (or volume) of the incoming signal and creates

a control signal, which modulates the wet signal in the same

manner as an auto-wah. The MOD SOURCE knob can set the

modulation direction either forward ( ) or backward ( ).

SPEED Knob (B)

Depending on the modulation source, the SPEED knob controls either

the rate of the LFO, the attack and decay times of the envelope follower,

or the smoothing of Hot Hand.

When using LFO modulation, turning the SPEED knob clock-wise will

increase the modulation rate.

When using an envelope follower, turning the SPEED knob clock-wise

increases the envelope attack, which determines how quickly the enve-

lope rises after the input level increases—the decay rate is the amount
