Spread
Positive values on the “y” axis (above the default, centered position) increase the delay
time of the right delay line and decrease the delay time of the left delay line—in effect,
“smearing” the delay times of the left and right channels. Negative values reverse this.
Spread is useful for “wide” stereo delay effects.
Groove
This parameter (on the “x” axis) allows you to reduce the delay time of one delay line by
a given percentage, while keeping the other delay line constant. Basically, Groove
distributes the delay taps to the left/right channels, rather than “smearing” them, like
Spread. Keep an eye on the small Help Tag while adjusting.
As an example, a value of + 50% reduces the right delay time by half. If a value of 1/4
was used as the Delay Base Time, the right delay would equal 1/8th of a note and the
left delay would remain at 1/4 of a note. Needless to say, this parameter is perfect for
the creation of interesting rhythmic delays—in stereo.
Note: You can create some truly wide “chorus” and “modulated delay” effects by
modulating the Pickup Position and Pickup Stereo parameters (with an LFO or other
modulator), and then feeding this into the Delay unit.
Body EQ/Spectral Shaping
Model-based spectral shaping. It can work as a simple EQ, as a complex spectral shaper
or as body response simulator. In effect, the Body EQ can emulate the resonant
characteristics of a wooden or metallic “body”—such as that of a guitar or violin.
The various models are derived from Impulse Response recordings of instrument
bodies. These recordings have been separated into their general formant structure and
fine structure, allowing you to alter these properties separately.
