CHAPTER 19. LIVE AUDIO EFFECT REFERENCE 240
19.4 Chorus
The Chorus Effect.
The Chorus effect uses two parallel time-modulated delays to create chorus (thickening) and
anging effects.
Each delay has its own delay time control, calibrated in milliseconds. Delay 1 has a highpass
lter that can remove low frequencies from the delayed signal. Greater highpass values let
only very high frequencies pass through to Delay 1.
Delay 2 can switch among three different modes. When off, only Delay 1 is audible. In Fix
Mode, only Delay 1's delay time will be modulated. When Mod is activated, Delay 2 will
receive the same modulation as Delay 1.
To set both delay lines to Delay 1's delay time, turn on the link button (=). This is especially
useful if you want to change both delays with a single gesture.
The Modulation X-Y controller can impart motion to the sounds. To change the modula-
tion rate for the delay times, click and drag along the horizontal axis. To change the amount
of modulation, click and drag along the vertical axis.
You can also make changes by entering parameter values in the Amount and Rate elds be-
low the X-Y controller. The Amount value is in milliseconds, while the modulation frequency
rate is in Hertz.
Clicking the *20 switch multiplies the modulation frequency by 20 to achieve more extreme
sounds.
The Feedback control determines how much of the output signal feeds back into the input,
