Real-time Control of KDFX
KDFX in Auto Mode

KDFX in Master mode
So far weÕve been telling you that setting FX Mode to ÒMasterÓ on the Effects page disables
real-time control over KDFX, but this is not strictly true. In that mode, KDFX will respond to
speciÞc system-exclusive (Sysex) commands. If you are a serious Sysex jockey, you can take
advantage of this by using Sysex commands.
Sysex, in fact, can be used to control KDFX regardless of the FX Mode setting, so if you need to
tweak certain parameters in real time without setting up an FXMod to do it, you can use Sysex.
ThereÕs no reason why you canÕt use Sysex control and FXMod control simultaneously, and in
fact if you have a situation in which you need to control more than 18 parameters at a time (the
maximum number of FXMods in a Program or Setup), you can use Sysex for the extra ones.
The Sysex commands for controlling KDFX are described in Appendix C of this manual.
Internal Effects in Master mode
The internal effects processor, which normally is controlled through a Program or Setup in one
of those modes, can also be controlled in Master mode. Unlike KDFX in Master mode, this is
done through Continuous Controller commands, not Sysex. The table that shows how to
address the parameters is in Chapter 3 of the
K2500 Reference Guide .
For these Controller commands to work with internal effects, the K2500 must be in Master
mode, which means that Program or Setup control over the internal effects cannot be used
simultaneously.
KDFX in Auto Mode
When the FX Mode is set to ÒAutoÓ, then control of KDFX changes according to where you take
the K2500: either Program mode or Setup mode. But when you are on the Effects Mode page
itself, you are actually in
Master mode. Therefore, you can go into the Studio whose name
appears on the page and tweak its parameters, but you wonÕt see any FXMods that might be in
place. If you change a parameter that has an FXMod link attached to it through a Program or
Setup, you wonÕt disturb that linkÑwhen you go back to the Studio through the Program or
Setup, the link will still be there.
However, if you have gone into a Studio from the FX Mode page, tweaked it, and then saved it,
then when you go into Program or Setup mode and call up a Program or Setup that links to that
Studio, any changes you have made in the Studio will show upÑand any parameters that you
changed that had been under FXMod control will no longer be linked.
From Auto Mode to Song Mode
When you are on the Effects page and if FX Mode is set to ÒAutoÓ, and then you go into Song
Mode, something slightly different happens: KDFX is now under control of the Program that is
on the Effect Channel within the songÑfrom
Song mode press Edit and look at the
ÒEffectChanÓ parameter.
The Effect Channel is saved with the song, so make sure that it is set so that the program that
you want to be in control of KDFX is active.
More about KDFX in Song mode in Chapter 6.
