2.4.1 Extra Messages – 128 To 131
You may have noticed that although we have stated there are 128 MIDI controller messages (0 – 127), Appendix C shows 132
assignable controller messages. This is because messages 128 – 131 are a different type of MIDI message, defined in the General
MIDI Specification as RPN messages. You can assign these to the controls on your Axiom keyboard in exactly the same way as any
other MIDI controller message. The RPN messages control the following:
Controller Number MIDI Message Use
128 Pitch Bend Sensitivity Alters the range of a pitch bend message
129 Master Tune (coarse) Adjusts the tuning of your sound module or synthesizer in large steps
130 Master Tune (fine) Adjusts the tuning of your sound module or synthesizer in small steps
131 Monophonic Aftertouch* Adds a vibrato effect
*Monophonic aftertouch is not an RPN message. However, it is an additional effect message defined in the General MIDI specification
and this is why we have included it in Appendix C.
2.4.2 Programming the Controls on Your Axiom
When programming a physical controller on your Axiom, the controller that was last used will be the first one selected for
programming. To select a different physical controller for programming, use one of the following two methods:
Method 1:
25-, 49- and 61-note versions:
< Move the physical controller you wish to program, or press the assignable button or pad.
Method 2:
49- and 61-note versions:
< Press Chan Assign and Ctrl Assign together to access the Ctrl Select setting.
< The LCD display will flash the last used control.
< Use the numeric keypad to enter the number of the physical controller you want to select for programming.
25-note version:
< Press the Advanced button.
< Press the Ctrl Select key on the keyboard.
< The LCD display will show the last used control.
< Use the numeric data entry keys to enter the number of the physical controller you want to select for
programming.
< Press the Enter key to confirm and return to performance mode.
The advantage of method 2 is that you do not have to move a control to select it – so there is no danger of disturbing a
parameter on the MIDI device you are controlling.
Programming a control:
49- and 61-note versions:
< Select the physical controller for programming using method 1 or 2 above.
< Press the Ctrl Assign button.
< The LCD display will show the currently assigned MIDI controller number The physical controller you are
programming is displayed in the bottom left hand corner of the LCD display for clarity.
< Use the numeric keypad or the -/+ buttons to enter the MIDI controller number 0-131 as defined in Appendix C.
