Delay:
The average delay between original and chorus signals.
Feedback:
The amount of delay which is routed back to the delay input. High
Feedback settings make "tunnel" or "tight steel cable" effects.
Modulation Rate:
The rate at which pitch is "wobbled."
Random:
Make the modulation Rate slightly unstable, so it has a less
mechanical sound.
Depth:
The amount of pitch modulation. If Depth is set too high, the effect will
have an objectionable out-of-tune sound. At slow Rate, you can use high Depth
settings, but at fast Rate, lower Depth settings are recommended.
Flange:
A distinctive, hollow, whooshing effect. It is caused by mixing a signal
with a very short delay.
The delay causes a comb filter effect, where there are many peaks and dips in
the frequency response. As the Flanger sweeps up and down, all the peaks and
dips sweep up and down, with the spacing of notches constantly changing.
Many Flangers have controls for Delay and Modulation depth. However, since a
Flanger acts like a filter, we have implemented our Flanger with frequecy knobs
instead.
Min Base Freq/Max Base Freq:
These two knobs set the upper and lower
limits of the first peak or notch in the comb filter. To get a wider sweep, set a
wider distance between Min and Max Base Freq.
Resonance:
The amount of Flanger feedback. High resonance settings make the
peaks louder and the notches deeper, creating a more pronounced effect.
Invert:
Invert the delay against the original signal.
Invert
and
non-Invert
have
distinctly different Flange sounds, with the
Invert
version being a bit more
"classic."
With
Invert enabled
, low frequencies are attenuated, and the first filter Peak is
at the Base Frequency. With
Invert disabled
, low frequencies are not
attenuated, and the first filter Notch is at the Base Frequency.
Invert might be better on guitar, but non-Invert may be better on bass guitar.
Modulation Rate:
The rate that the filter sweeps between the Min and Max
Base Frequencies.
