Real-time Control of KDFX
Setting up FXMods
4-4
In addition, there are a few parameters that can cause serious glitching if they are changed in
real time. The most common of these are the ÒRoom TypeÓ settings in reverb Algorithms, which
can create clicks and pops when they are changed while signal is passing through them. While
there is nothing in the software to prevent you from assigning an FXMod to Room Type, you
need to be cognizant of the potential consequences. See ÒStatic FXModsÓ later in this chapter.
ÒAdjustÓ setting
The Adjust setting is the starting value of the selected parameter when it is under KDFX
control, similar to the Entry value of a controller in a Setup. This might very well be different
from the value of the parameter when the Studio is
not under FXMod control, so donÕt get
confused. If you are in Program mode, and this is the current Program, the Adjust value takes
precedence over the StudioÕs Þxed value, and itÕs the Adjust value that will be called up when
you call up the Program.
Source
The Source parameter determines which real-time controlÑinternal, MIDI, etc.Ñis going to
affect the selected Studio parameter. As with all K2500 real-time controls, the range of control
sources is very large:
¥
OFF (the parameter is not affected by any source and stays at its ÒAdjustÓ value)
¥
ON (the parameter is set to the maximum value determined by adding the Adjust and
Depth values)
¥
MIDI Continuous Controllers 1-95*
¥
Channel State
¥
Pressure
¥

¥
the usual software controllers, as described in Chapter 6 of the K2500 Reference Guide :
ASRs, FUNctions, Clocks, LFOs, Internal Controls, Random Generators, etc.
*Under some circumstances, particularly when the K2500 is in Setup mode, there are certain
restrictions on which MIDI sources you can use. This is explained later in this chapter, in the
section ÒEnabling Controllers in Setups and ProgramsÓ.
Dedicated FXMod control sources
A few new control sources, usable only within FXMods, have been added to the list:
¥
FXLFO1, FXLFO1ph, FXLFO2, and FXLFO2phÑtwo LFOs and their phases.
¥
FXASR1 and FXASR2Ñ two three-stage (Attack/Sustain/Release) envelopes with
selectable triggers and Normal, Hold, and Repeat modes.
¥
FXFUN1, FXFUN2, FXFUN3, and FXFUN4ÑFunctions. Yes, more Fun with KDFX!
These LFOs, ASRs, and FUNs work exactly the same way they do in any other part of a
Program, except these are extra control sources for use
only with FXMods, and are not available
for other VAST Program functions. They are global for all of the FXModsÑeach Bus does not
have its own.
Their parameter values are saved with the Program. As we saw earlier, you get to the pages for
their parameters by pressing the
