phase with each other, creating stereo movement. Set to 180, the LFO outputs are 180
degrees apart, so that when one LFO reaches its peak, the other is at its minimum.
Spin detunes the two LFO speeds relative to each other. Each stereo channel is modulated
at a different frequency, as determined by the Spin amount.
For sample and hold, the Phase and Spin controls are not relevant and do not affect the
sound. Instead, the Auto Filter offers two kinds of sample and hold: The upper sample and
hold type available in the chooser provides independent random modulation generators for
the left and right channels (stereo), while the lower one modulates both channels with the
same signal (mono).
21.3 Auto Pan
The Auto Pan Effect.
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.
