Auto Pan offers LFO-driven manipulation of amplitude and panning for creating automatic
panning, tremolo and amplitude modulation, and beat-synchronized chopping effects.
Auto Pan's LFOs modulate the amplitude of the left and right stereo channels with sine,
triangle, sawtooth down or random waveforms.
The Shape control pushes the waveform to its upper and lower limits, hardening its shape.
The waveform can be set to Normal or Invert (use Invert to, for example, create the
saw up waveform from the saw down waveform).
LFO speed is controlled with the Rate control, which can be set in terms of hertz. Rate can
also be synced to the song tempo.
Though both LFOs run at the same frequency, the Phase control lends the sound stereo
movement by offsetting their waveforms relative to each other. Set this to 180 , and the
LFOs will be perfectly out of phase (180 degrees apart), so that when one reaches its peak,
the other is at its minimum. Phase is particularly effective for creating vibrato effects.
The Offset control shifts the start point of each LFO along its waveform.
The device's in uence on incoming signals is set with the Amount control.

Beat Repeat
The Beat Repeat Effect.
Beat Repeat allows for the creation of controlled or randomized repetitions of an incoming
signal.
