System Exclusive Control of KDFX Parameters
Appendix C-3
Here are some examples of parameter values encoded into LSB and MSB:
Parameter value hexadecimal MSB LSB
(decimal)
255 00FF 01 7F
200 00C8 01 48
128 0080 01 00
127 007F 00 7F
0 0000 00 00
-1 FFFF 7F 7F
-50 FFCE 7F 4E
-128 FF80 7F 00
While this may seem complex, if you are using a dedicated controller to generate Sysex, you
may not need to worry about encoding parameter values, because the controller will do it for
you. For example, with one popular MIDI fader box, the following will give you control of
wet/dry mix for the Aux bus effect:
Function = String
String = F0 07 00 78 1B 2A 00 pr pr F7
Min = 0 Max = 100
Param format = 2Byte,7Bits,hi->lo
Note: Sysex disables FXMods
If a parameter is assigned to an FXMod, and you then modify it by Sysex control, the FXMod
will be temporarily disabled. It will re-establish itself the next time the Program or Setup is
selected.
Sysex and the rest of the K2500
Information about using Sysex with other aspects of the K2500 can be found in Chapter 11 of
the
K2500 Reference Guide .
