other current program parameters, will not address KDFX. If FX Chan is set to Current then you 
donÕt have to worry about this.
Performance Modes and Effects Control
HereÕs how to tell whatÕs controlling what, depending on the various modes. See FX Channel 
below for information about the MIDI channel for external control of KDFX. Note that you can 
use SysEx commands to control KDFX regardless of the setting for FX Mode.
Using KDFX With a Sequencer
If you use an external MIDI sequencer, you are probably thinking about how powerful it will be 
putting KDFX under sequencer control. Certainly being able to record, edit, and automate a 
studioÕs parameters as part of a MIDI sequence is one of the most attractive aspects of KDFX.
FX Channel
Any program on any channel can be the one that controls KDFX. On the Effects-mode page, set 
FX Mode to Program, select the FX Channel you want to control KDFX with, and put your 
KDFX-controlling program on that MIDI channel. Now any MIDI commands coming from the 
sequencer on that MIDI channel will be sent to KDFX.
Dedicating a Program and Channel
Perhaps the most efÞcient and least confusing way to do this is to have a dedicated program that 
controls only KDFX, on a channel that is otherwise not being used to play music. Many K2500 
and K2000 users know this trick for automating the old internal effects, but it becomes even 
more important given the complex nature of KDFX. It requires sacriÞcing a MIDI channel, but 
few users should have a problem with that.
Again, go to the Effects-mode page and, keeping the FX Mode set to Program, set the channel 
youÕre going to use as an FX ChanÑin this case, 15 is often a good choice. Go to Program Mode 
and select Program 199 Default Program. Press Edit, and then KEYMAP, and set the Keymap 
parameter to a value of 0 None. This program will now make no sound in response to MIDI
