22 Expression Pedal Input

This socket accepts both “switch type” and standard expression Pedals such as M-Audio EX-P for adding

expressive changes during performances. The Expression Pedal input is fully MIDI-assignable, and a

unique MIDI CC can be assigned for each keyboard Zone, so that the message(s) sent are defined by the

active Zone(s).

For a list of supported assignments, see Appendix A, “Standard MIDI Control Numbers (MIDI CC’s)” and

Appendix B, “Assignable MIDI CC’s”

23 Sustain Pedal Input

This socket accepts momentary-contact foot Pedals (not included). When pressed, this Pedal will sustain

the notes you are playing, without having to keep your fingers pressing down the keys. The Sustain Pedal

input is fully MIDI-assignable, and a unique MIDI CC can be assigned for each keyboard Zone, so that the

message(s) sent are defined by the active Zone(s).

For a list of supported assignments, see Appendix A, “Standard MIDI Control Numbers (MIDI CC’s)” and

Appendix B, “Assignable MIDI CC’s”

24 MIDI In Port

This standard 5-pin MIDI connector receives data from any MIDI compatible device such as a synthesizer

or drum machine.

This port also allows you to use Axiom as a MIDI interface to send MIDI data from external hardware to

your DAW. In this instance, the 3rd USB MIDI input should be selected from those available in the DAW

preferences. Please refer to the documentation provided with your DAW for further information on MIDI

configuration.

25 MIDI Out Port

This standard 5-pin MIDI connector transmits data to any MIDI compatible device such as a synthesizer,

sound module, or drum machine.

In MIDI Out “From USB” Mode, data sent to the Axiom USB MIDI Output port (not the DirectLink port)

will be streamed to the external MIDI Out port. Please refer to Chapter 4, “Advanced Keyboard Functions”

for further information on MIDI Out from USB.

26 USB Port

The USB 2.0 port (backward compatible with USB 1.1) delivers power to Axiom and transmits MIDI data

to and from the host computer.

27 Power Supply Jack

Connect an optional 9VDC power supply here when controlling external MIDI hardware in a live situa-

tion. This connection is not to be used while Axiom is connected to a host computer using the USB Port.

28 On/Off Switch

Use this switch to power the device on or off whether Axiom is connected via USB or controlling external

hardware.

The polarity of the Sustain Pedal is determined by Axiom upon startup. When powering up, it assumes the

Pedal is in the “up” (off) position. It is important that the Sustain Pedal is not pressed down during

startup, otherwise its operation will be reversed.
