Named because it makes one instrument sound like
many. Fills up the sonic space in a song
A chorus is merely a flanger with longer delay times
(and usually no feedback)
The following parameters determine the sound from a
flanger
Delay - The minimum amount of time the signal is
delayed. (20-30 ms).
Sweep depth (width) - How wide the sweep is in terms of
delay time. i.e. the maximum
additional delay time added as the LFO is swept (0 to 10 ms)
Speed the frequency of the LFO
Extreme settings will create a vibrato pitch
