PITCH PARAMETERS:
Delay: Changes the predelay time in ± 1 millisecond steps. The total amount of predelay is 1 second (1000 ms.)
Size: Changes the predelay time in ± 50 millisecond steps.
Regen: Sets the amount of delay feedback, from 0 to 99.
Decay: With the Gated class, this control sets the fade time of the effect after it has been dynamically triggered. In
the Dynamic class, Decay sets the amount of time it takes the Whammit! effect to glide to and from its
target pitch after being dynamically triggered. This control follows a linear curve and its range is from 0
(short) to 31 (long).
Shape: Sets the internal buffer size. A setting of 1 is the longest buffer length and 4 is the shortest. Short buffer
sizes have the least amount of transport delay and work best on percussive material. However, they may
sound rough at large Pitch settings or with sustained material. Use your ears to determine which buffer size
is the best for the current application.
Pitch: Sets the amount of pitch transposition with a range between 12.7 half steps up or down (±1.27 half steps in
Vocal class). This range has an extra setting of -24 half steps (-2.4 in Vocal class) to produce two-octave
bass-doubling effects.
Speed: (Not used.)
Width: This parameter is used in Vocal and Ambient classes and sets the second channel’s pitch transposition. Its
range is the same as the Pitch parameter’s and it is not available in Discrete 4 routing.
Special: In Gated class, Special sets the audio input level (Threshold) that controls the gating action of the effect.
This parameter can be set in 1-dB increments, from 1 to 30 dB below full-scale. Normally, when the input
signal is above the Threshold setting, the PT is muted. With signals below the Threshold, the PT is heard. If
the value in the Display is preceded by an r ( ), this gating action is reversed; signals above the Threshold
setting are transposed and ones below are not.
