Advanced KDFX
Real-time Control of KDFX
Tap Tempo
A real-time tap on a footswitch or button can also be used to control the tempo of a parameter in
KDFX. Like Tempo, Tap Tempo is not KDFX-speciÞc, but can be used throughout the K2600Õs
operating system, including the sequencer.
Tap Tempo is on the Control Source list for any controller in a setup or control setup, located at
number 39. Tapping or pressing on a controller that is set to Tap Tempo sends tempo
information, based on the average time between taps, to the Internal Clock.
It takes four taps to determine the tempoÑif you tap fewer than four times, no information is
sent. If you tap more than four times, the average of all of your taps is continuously calculated
and sent to the Clock. Later taps are weighted more heavily than earlier ones, so that if you
change the rate at which you tap, the tempo information being sent will change accordingly, but
there is a ÒßywheelÓ effect, and the ClockÕs tempo changes will lag somewhat behind the
changes in your tapping rate.
In order for Tap Tempo to have any effect, the Clock parameter on the Song Mode:MISC page
must be set to Internal.
KDFX in Master Mode
So far weÕve been telling you that setting FX Mode to Master 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
and also use the FXMods in a program or setup.
See Appendix B in the MusicianÕs Reference for details about using SysEx to control KDFX.
KDFX in Auto Mode
When the FX Mode is set to Auto, then control of KDFX changes according to where you take
the K2600: 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 there wonÕt be any FXMods. You can change
a parameter that has an FXMod link through a program (or setup), but, unlike when you are
going into the studio through a program, that link will not be disturbed.
When you leave the studio, and then go into Program or Setup mode and call up a program or
setup that links to that studio, any changes you have just made in the studio will show up, and
any FXMods previously in place will also still be there.
From Auto Mode to Song Mode
When you are on the Effects-mode page and if FX Mode is set to Auto, 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
EffectChan 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.
