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 Frequency
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:
whole notes) to 16 (64
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 Micron's tempo. When "follow tempo" is
selected, the LFO Rate parameter is displayed as a
multiple of the Tempo.

–100% to 0 to +100%
