Super Phaser

The classic phaser effect is created by ganging multiple all-pass filter
stages to create "notches," or sharp dips in the frequency spectrum. The
frequencies of these all-pass filters are usually modulated by an LFO to
create a dramatic sweeping sound. The Super Phaser follows this classic
formula but allows you to select from 4 to 64 all-pass stages for a wide
variety of timbres.
A . Feedback
This is the amount of the phaser output added back into the input to
produce a deeper effect.
Range:
B . Notch Freq
This is the frequency of the first (lowest) notch, un-modulated by
the LFO.
Range:
C . LFO Rate
This is the rate of the Low Frequency Oscillator.
Range:
enabled
D . LFO Depth
This adjusts the magnitude of the LFO modulation. When set to
0%, the LFO has no effect on the notch frequencies.
Range:
E . LFO Shape
This selects between the two LFO shapes.
Range:
F . Stages
This selects how many all-pass filter stages, and thus notches are
used.
Range:
G . Tempo Sync
This selects whether the LFO rate is synchronized to the System
Tempo. When enabled, the LFO Rate parameter is displayed as a
multiple of the Tempo.
Range:
82
–100% to 0 to +100%
0 – 100%
0.010Hz – 4.800Hz, or 1/16 to 16 if Tempo Sync is
0 – 100%
