K2600 Version 4 (GM Mode) User’s Guide
This document describes General MIDI (GM Mode), a new feature included with Version 4 of the K2600 Operating 
System. To get started with GM Mode, you must first use the Boot Loader to install the Version 4 software on your 
K2600. This procedure is described in Appendix A of the 
K2600 Musician’s Guide
. 
You must perform a hard reset after you install this new operating system.
 
What it is
Version 4 of the K2600 Operating System introduces GM Mode, an efficient way to use your K2600 with General 
MIDI devices and sequences. Since you can turn GM Mode on or off in a single step, you can easily move between 
the K2600’s normal operating mode and GM Mode. The K2600 remembers your Master table settings, so when you 
leave GM Mode to return to normal operating mode everything is right where you left it. 
GM Mode is optimized for use with the K2600 ROM 5 and Orchestral ROM options. Installing these optional 
soundsets in your instrument is your best bet for top-notch GM sounds. You may, however, take advantage of GM 
Mode without installing the option ROMs. See “Using GM Mode without ROM5 and Orchestral ROM,” below, for 
more information.
 
About GM
General MIDI (GM) is an addition to the original MIDI specification that assigns sounds to specific channel num-
bers, program numbers, and note values. Using General MIDI, you can share song files between different devices 
with reasonably consistent performance. 
Many GM song files are commercially available, and they’ll sound great on your K2600.
