M-Audio AIR 25 user manual Rear Panel, Main Control Panel

8.	Main Control Panel:
	A. LCD: This screen displays useful information, such as
	the current assignment and setting of the most	B		D
	recently moved physical control.
	B. Edit Button: This button puts Axiom AIR in Edit Mode,		A
	allowing you to use its keyboard's special functions to	C		E
	create or edit MIDI control assignments, global
	settings, and utility functions.
	C. Tempo Button: This button flashes in time with the		G
	tempo setting of the trigger pad roll function. Tap this
	button at 1/4-note intervals to set the tempo. Press
	and hold this button for over two seconds to set the
	tempo manually, using Knob 8 or the up and down		F F F	F F F
	Directional buttons. Press the center Directional button

to save the setting.

Note: When Axiom AIR receives incoming MIDI timecode (MTC) messages, it will automatically synchronize with the external MIDI clock. These messages can be received only over Axiom AIR's USB port.

D.Identify Button: Hold down this button and move a control to identify its assignment, which will appear in the LCD. This lets you identify what is assigned to that control without actually sending out any MIDI data. This is useful for reminding yourself of your assignments without changing your settings, disrupting your live performance, etc. You can double-press this button to "latch" it so it stays on. Press it once again to unlatch it.

E.Memory Button: This button lets you save and access Memory Locations for storing full MIDI configurations. See the Memory Locations section of this manual for more information.

F.Transport Controls: These buttons control standard transport functions in DAW software: loop, rewind, fast-forward, stop, play, and record. When a HyperControl-enabled DAW is running, these buttons automatically map to those functions (or their closest alternatives). You can also map these buttons to a variety of MIDI messages.

G.Directional Buttons: You can use these buttons for various navigational and parameter-setting functions, depending on the setting of the adjacent Mode buttons.

•Inst/FX Mode (INST/FX button): The buttons will select the track and plug-in you want to control with the faders and knobs.

•HyperControl Mode ( button): The buttons will have alternate, DAW-specific uses.

•Track Select/Bank Mode (Track button): The buttons will select the desired track or bank of tracks to control in HyperControl Mode.

1.Power Switch: Use this switch to power Axiom AIR on or off.

2.Power Input: Connect an optional power adapter here (9V DC, 3A, center-pin positive, sold separately). Alternatively, you can power Axiom AIR via the USB port of your connected computer.

3.USB Port: When Axiom AIR is connected to a computer via USB, this USB connection powers Axiom AIR and transmits MIDI data to and from the computer.

4.MIDI Input: Use a standard 5-pin MIDI cable to connect this input to the MIDI output of an external MIDI device.

5.MIDI Output: Use a standard 5-pin MIDI cable to connect this output to the MIDI input of an external MIDI device, allowing you to play the sounds in a MIDI sound module or a rack synth, for example.

6.Expression Pedal Input: Connect either a "switch"-type or standard expression pedal (sold separately) to this input to allow for expressive changes while performing. This input is assignable to different functions.

7.Sustain Pedal Input: Connect a momentary-contact sustain pedal (sold separately) to this input to allow you to sustain the currently playing notes without having to hold the keys down. This input is assignable to different functions.

Note: When you power on Axiom AIR, verify that your sustain pedal has the right "polarity" – that it sustains notes when pressed down. If your sustain pedal is working "in reverse," remove your foot from it, and power your Axiom AIR off then on again. (When powering on your Axiom AIR, it scans the sustain pedal as being in the raised/off position.)

8.Kensington® Security Slot: This connector is compatible with standard laptop-style Kensington security cables for theft protection.
