Appendix C
System Exclusive Control of KDFX Parameters
Any KDFX parameter that can be assigned to an FXMod can also be controlled by MIDI system
exclusive ("Sysex") commands. Controlling KDFX parameters using Sysex can be more
complicated than programming an FXMod, but allows more ßexibility. ItÕs especially useful
when the K2500 is in Master effects mode, and it is also a way to use additional real-time
control above the 18 FXMods that are allowed in a given Program or Setup.
A Sysex message to control KDFX starts with the standard K2000/K2500 Sysex format (all
numbers are hexadecimal):
F0 start of sysex
07 manufacturer ID = Kurzweil/Young Chang
NN unit ID, typically 0
78 product ID = K2000/K2500
1B message type = KDFX parameter control
Then a ÒDeviceÓ, or section of a KDFX Studio, is selected. Then a speciÞc Parameter within the
Device is selected, and its value set:
NN KDFX Device select, valid Devices are 0-46 (decimal)
NN KDFX Parameter select, valid range depends on selected device
NN parameter value MSB
NN parameter value LSB
And Þnally the standard End of Exclusive byte:
F7
Device Codes
Here are the Device codes for each of the different parts of the KDFX Studio (numbers are
decimal):
Device KDFX part
0 Send1 for Input A (or A/L if mono input)
1 Send1 for Input A/R (if mono input)
2 Send1 for Input B (or B/L)
3 Send1 for Input B/R
4 Send1 for Input C (or C/L)
5 Send1 for Input C/R
6 Send1 for Input D (or D/L)
7 Send1 for Input D/R
8-15 Send2 for Inputs A thru D (for stereo input, use even # devices)
16-23 EQ1 for Input A thru D
24-31 EQ2 for Input A thru D
32,34,36,38 Aux send for FXBusses 1-4
33,35,37,39 Mix send for FXBusses 1-4
