Description
DEPTH
CC 1
Controls the depth of the LFO, determining how prominent the flanger effect is. Fully counter-clockwise is most subtle, fully clockwise is most prominent.
SPEED
CC 2
Controls the frequency of the LFO (1-10 Hz). Determines how fast the flanger effect cycles. When MIDI Clock is active, controls beat subdivisions instead (quarter/eighth/triplet/sixteenth).
RESONANCE
CC 3
Sets the resonance of the peak/notch filters in the flanger effect. Higher resonance produces a more metallic, bell-like or chime-like sound; lower resonance is more subdued.
DELAY
CC 4
Sets the base delay time for the flanger effect. Lower delay times create a pronounced tape-style "whoosh" sound, longer delay times produce a less pronounced effect that can resemble a chorus.
