note) of delay. With Sync Mode active, changing the Delay Time field percentage value short-
ens 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 field, or click in the field and type in a value.
The Delay Time can also be routed to the horizontal axis of the X-Y controller.
The Spray control adds random delay time changes. Low values smear the signal across time,
which adds ”noisiness” to the sound. High Spray values completely break down the structure of
the source signal, introducing varying degrees of rhythmic chaos. This is the recommended set-
ting for anarchists.
The size and duration of each grain is a function of the Frequency parameter. The sound of Pitch
and Spray depends very much on this parameter.
You can transpose the grain pitch with the Pitch parameter, which acts much like a crude pitch
shifter.
The Random Pitch control adds random variations to each grain’s pitch. Low values create a sort
of mutant chorusing effect, while high values can make the original source pitch completely unin-
telligible. This parameter can interact with the main Pitch control, thus allowing degrees of stabil-
ity and instability in a sound’s pitch structure.
The Feedback parameter sets how much of the output signal returns to the delay line input. Very
high values can lead to runaway feedback and produce a loud oscillation — watch your ears
and speakers if you decide to check out extreme feedback settings!
Grain Delay also has a dry/wet control, which can be routed to the vertical axis of the X-Y con-
troller.
