About FX Presets
3-12
Notice also as you scroll the Algorithms, the ÒEffectSizeÓ parameter in the upper-right corner
changes. This parameter shows how many Processing Allocation Units (PAUs) the currently
selected Algorithm requires, followed by how many are available for the Bus this FX Preset is
on. If, for example, EffectSize is Ò2/3Ó, that means the algorithm requires 2 PAUs, and there are
3 PAUs available. More about PAUs in a moment.
Just below and to the right of the Algorithm name is an Input Gain parameter, which adjusts
the level of the signal coming into the FX Preset from the input(s) sending to it. While the
relative level of the different inputs is determined on the Input pages, you can change the
overall level hereÑfor example, if youÕve combined several inputs into one FXBus and the
signal is too hot for the FX Preset, you can pad it down here. The Trim is adjustable from
Off/-79.0 dB to +24 dB.
Below the Input Gain is usually (but not always) an Output Gain, which sets the level of the
signal leaving the FX Preset, which can be further modiÞed by the Mix and Aux sends on the
FXBus page.
The other parameters that appear on this page are determined by the Algorithm. Each
Algorithm has its own set of parameters, which may take up as many as four pages, accessed
using the soft buttons
PARAM2 , PARAM3 , etc. The parameters associated with each
Algorithm are discussed in detail in Chapter 5 and in the KDFX Algorithm Reference .
When you change a parameter on one of these pages, you have changed the FX Preset, and if
you want the change to be permanent, you must save the FX Preset. Pressing either of the
more
soft buttons accesses Name, Save, Delete, and Dump pages for the FX Preset. FX Presets are
stored in RAM, just like K2500 Keymaps. When an FX Preset is recalled, either by itself (from
within the Studio Editor) or as part of a Studio, its associated Algorithm and all parameters are
recalled with it. If you modify an FX Preset and save it to its same location, then any other
Effects Buses in the Studio, or in any other Studio, that incorporate that FX Preset will now use
the modiÞed version.
There is another way to edit an FX PresetÕs parameters without altering the FX Preset itself, and
that is by using Bus Overrides.
Bus Overrides (Bus Mods)
We havenÕt yet talked about the two parameters that are on the FXBUS and AUXFX pages,
directly underneath the name of the FX Preset. These are called ÒBus OverridesÓ or ÒBusModsÓ,
and they allow you to change parameters within an FX Preset without actually going into the
FX Preset.
Wet/Dry||||:35%
Out|Gain|||:2.0dB
HereÕs an example of what they do. The Bus Overrides on FX1 are often Wet/Dry mix and
Output gain. Normally, these parameters would be found inside the FX Preset, and if you
changed them, youÕd have to save the new FX Preset in order to keep the changes.
