2.4MIDIControllerMessages
There are 128 MIDI controller messages that are used for controlling the MIDI-adjustable parameters in your software or on your
external MIDI gear. Examples of these controllable parameters include volume, pan, expression, reverb, chorus and portamento.
Each of the controls on your Axiom keyboard is able to send any of the 128 standard MIDI controller messages to control such
parameters. Please note that in order for these effects to work, the MIDI device you are sending to must be able to receive these
messages. A full list of these control messages is given in Appendix C.
For example, you may want to set the Modulation wheel to control the reverb amount. This is done by assigning controller 91 to the
Modulation wheel (control A10 on Axiom 25, control A19 on Axiom 49 and Axiom 61). .
Examples of other popular effects are listed in the table below. (Please consult Appendix C for the full list.)

There are many different types of virtual instruments available and most of these respond to MIDI controller messages, allowing
you to control a variety of parameters from your Axiom keyboard. Please review the manual that came with your software or
external gear to see what these controller numbers are.
2.4.1ExtraMessages128To131
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, dened in the General
MIDI Specication 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 NumberMIDI MessageUse
128Pitch Bend SensitivityAlters the range of a pitch bend message
129Master Tune (coarse)Adjusts the tuning of your sound module or synthesizer in large steps
130Master Tune (ne)Adjusts the tuning of your sound module or synthesizer in small steps
131Monophonic Aftertouch*Adds a vibrato effect
*Monophonic aftertouch is not an RPN message. However, it is an additional effect message dened in the General MIDI specication
and this is why we have included it in Appendix C.
