General Parameters
There are a number of Parameters that are common to all or almost all Algorithms, and weÕll
deal with those Þrst.
Wet/Dry balances the levels of the processed and unprocessed signals passing through the
FXPreset. The range is 0% wet (the signal is unprocessed) through 100% wet (no dry signal is
present). A setting of 50% wet means the dry and processed signals are equal in level. In some
Algorithms, 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.
In Gain sets the level of the signal coming into the FXPreset from the Input page. As with most
Gain controls in KDFX, the range is -79.0 dB to 24.0 dB, and there is an ÒOffÒ position. 0.0 dB is
unity gain.
Out Gain sets the level of the signal after it passes through the FXPreset. From here the signal
goes directly to the Output page, if one of the Outputs is set to ÒFXBus n Ó. The level can be
further changed (on the FX Bus page) before it goes to the Mix and/or AuxFX buses.
In/Out enables or disables the effect. You can think of it as a Wet/Dry parameter with only two
positions: 100% (In) and 0% (Out).
HF Damping is the cutoff (-3 dB) frequency of a 6dB/octave lowpass Þlter thatÕs inserted
before the processor. 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 Þlter, and will therefore be
duller.
XCouple (Cross Couple). In stereo effects, this controls how much of any signal being fed back
is going to the channel opposite to the one where it Þrst appeared. At 100%, all feedback from
signals at the left input goes to the right channel and vice versa, causing a ÒspreadingÓ or in the
case of delay lines, a Òping-pongÓ effect. At 0%, fed-back signals stay with the channel they
came in on.
A->B cfg (conÞguration). In combination Algorithms that contain two (or more) components,
and whose name uses Ò<>Ó, as in 719 ÒReverb<>CompressÓ, the order in which the signal
passes through the two components can be changed. For example, this Algorithm can be
conÞgured so the signal passes through the reverb Þrst and then the compressor, or through the
compressor Þrst and then the reverb. The
cfg parameter determines the conÞguration, and its
value is context-sensitiveÑin this example, the choices would be ÒRvb->CmpÓ and ÒCmp-
>RvbÓ.
A/Dry->B is also found in many combination Algorithms, and controls the amount of signal
that will pass dry (unprocessed) through the Þrst component into the second component.
Different combination Algorithms use different variations on this parameter, depending on the
context. The range is 0 to 100%.
