Classic Mono Flange
The flanger effect impresses uniformly spaced sweeping notches on the sound spectrum. It accomplishes this using a variable comb filter, which works by mixing the input sound with a variably delayed-and-scaled copy of the input. Unlike the phaser, the flanger notches are uniformly spaced on a linear frequency scale, and there can be many more of them at low cost.
Parameters:
Rate
The Flanger Rate parameter sets the frequency of its LFO in Hz - performable
Master Rate
Tie the flanger rate to the system-wide Master Rate multiplied by the selected scale factor from the pop-over list below the button
Depth
Depth of spectral notches - performable - Depth = 0 means no effect, Depth = 1 means maximum effect (spectral-notch gains go all the way down to zero).
Delay
Maximum Delay (in ms) used by the flanger - the actual delay at any given time is between this value and zero.
Feedback
Gain applied to the output signal and then summed with the input signal - performable
Norm/Invert
The Normal setting of this switch results in adding the delay-line's input and output to obtain the flanging effect. The Invert setting uses subtraction instead of addition, thereby interchanging the notches with the "arches" defined by the response between the notches.
Waveshape
The LFO waveshapes are sine (0) and triangle (1), or any blend of the two
