7.4.15. Multi Filter

Sometimes it's nice to have an extra filter handy for tweaking your tone before it gets to the
output. The Multi Filter FX gives you five to choose from!
Filter Type is selected from the dropdown menu by clicking the arrow next to the
•
type name. Types include: lowpass (LP), highpass (HP), bandpass (BP), feedback
comb filter (CombFB), and feed forward comb filter (CombFF). The comb filters
simulate the behavior of a flanger with two different tonal qualities – CombFB
produces a series of evenly spaced peaks, and CombFF produces evenly-spaced
notches.

Evenly spaced? You can see on the display that they're not. Well, actually they are – by frequency ,
not by octave. The display is scaled in octaves, and each octave is double the frequency of the one
below it. As a result, the display shows a series of peaks that gradually get closer together.
CUTOFF: sets the cutoff frequency from 20.0 Hz to 20000 Hz (LP, HP, BP) or
•
2000 Hz (CombFB, CombFF)
RESONANCE: sets the resonance of the filter. (0.500 to 15.0)
