Effects Parameters
This section contains descriptions of the PC4's many effects parameters, and instructions
on how to use them. Read through this section to get a good general understanding of the
parameters.
The descriptions here do not include all of the parameters associated with every effect, and
some effects may not have some of the parameters described here for their category. A more
complete reference, with every effect and the meaning and range of every parameter, arranged
in the order they appear on the screen, can be found in the KSP8 Algorithm Reference Guide
on the Kurzweil website, www.kurzweil.com.

General Parameters

There are a number of parameters that are common to all or almost all effects, and we'll deal
with those first.
Wet/Dry balances the levels of the processed and unprocessed signals output from the effect.
Wet represents the processed signal, while dry represents the unprocessed signal. The range
is 0% wet (the signal is unprocessed) through 100% wet (no dry signal is present). Values
between 0% and 100% blend the two signals, for example, at 20% the output signal is
20% wet (processed) and 80% dry (unprocessed.) A setting of 50% wet means the dry and
processed signals are roughly equal in level. In some effects, separate Wet/Dry parameters
are provided for the Left and Right input channels. In some cases, this parameters can have
negative values, which indicate that the Wet signal is polarity-inverted.
When an effect with the Wet/Dry parameter is used in Chain that has been selected as an
Aux effect, Wet/Dry is automatically set to 100% wet and cannot be adjusted. This is because
when using an Aux effect, the dry signal is already effectively at 100% on the main audio bus
(not routed through the Aux effect.) In this case, turning up the Aux send level will blend the
100% wet signal (from the Aux bus) with the dry signal on the main audio bus.
Out Gain sets the gain at the output of an effect.
In/Out enables or disables the effect. You can think of it as a Wet/Dry parameter with only
two
HF Damping (high frequency damping) is the cutoff (-3 dB) frequency of a 6dB/octave
lowpass filter that's inserted before the processor. High frequencies above the set cutoff
frequency will be filtered out. In the case of processors where multiple iterations of the signal
are heard, such as in a delay, each iteration of the signal will pass through the filter, and will
therefore be duller.
