KB3 Mode buttons
The eight buttons above the sliders on K2500 keyboards have special capabilities in KB3 Mode. These include
changing the speed of the rotary speaker emulation, turning vibrato or chorus on and off, and various
percussion features. The buttons control both the K2500's internal effects, by the way, and also any external
MIDI devices to which you may be connected (see "MIDI Control of KB3", near the end of this document, for
a listing of the controller values transmitted).
Attach the "Assignable Controllers / KB3 Mode" label above the eight buttons on your K2500 keyboard. For
your convenience, a full size copy of this label is included on the last page of this document. These buttons
normally perform zone muting in Setup mode, so to use them as KB3 Mode buttons you must set the Mutes
parameter on the Setup Mode COMMON page (new in Version 2.5 software) to "KB3 Control". These buttons
will still do zone muting, however, unless there is an active KB3 program.

Editing a KB3 Program
You can edit a wide assortment of any KB3 program's parameters. You can also create your own KB3
programs, though you must start with an existing KB3 program to do this. A regular K2500 program cannot be
turned into a KB3 program. If you're not sure whether the current program is a KB3 program, check the
information box on the left side of the program display; it will indicate "KB3 Program" if that's what the
program is.
Enter the KB3 program editor by pressing the Edit button while a KB3 program is selected in program mode.
You'll quickly see that the KB3 editor differs from the standard V.A.S.T. program editor.
