20.13 Grain Delay
The Grain Delay Effect.
The Grain Delay effect slices the input signal into tiny particles (called grains) that are then
individually delayed and can also have different pitches compared to the original signal
source. Randomizing pitch and delay time can create complex masses of sound and rhythm
that seem to bear little relationship to the source. This can be very useful in creating new
sounds and textures, as well as getting rid of unwelcome house guests, or terrifying small
pets (just kidding!).
To refer delay time to the song tempo, activate the Sync switch, which allows using the Delay
Time beat division chooser. The numbered switches represent time delay in 16th notes. For
example, selecting 4 delays the signal by four 16th notes, which equals one beat (a quarter
note) of delay. With Sync Mode active, changing the Delay Time eld percentage value
shortens and extends delay times by fractional amounts, thus producing the swing type
of timing effect found in drum machines.
If the Sync switch is off, the delay time reverts to milliseconds. In this case, to edit the delay
time, click and drag up or down in the Delay Time eld, or click in the eld and type in a
value.
You can route each parameter to the X-Y controller's horizontal or vertical axis. To assign a
parameter to the X-axis, choose it from the parameter row below the controller. To assign a
