Hi,
If you are looking for a way to get the hex code for any specific instruction for your gear you can use a couple of apps.
https://www.snoize.com/# has two apps. A MIDI Monitor (which I used) and SysEx Librarian (enables you to record and playback Sysex messages)
I used this to determine the hex sysex code for my KRONOS which are as follows:
Combi Select:
F0 42 30 68 4E 00 F7
Program Select:
F0 42 30 68 4E 02 F7
The place where I got this info is
http://karma-lab.wikidot.com/misc:finding-sysex-messagesThey have links to windows versions too, although I haven't tried to use them as I am running Mac.
Enjoy...
Alan
