hank you for choosing the MidAir wireless MIDI system. The MidAir transmitter and receiver modules allow you to convert
any regular MIDI keyboard* into a wireless controller. This allows you to control your MIDI hardware or software without

T

cumbersome cables and gives you the freedom to place your keyboard anywhere that best suits your needs—you no longer have
to worry about cable lengths, wiring clutter, or accidents caused by cables on your stage or studio floor.

MidAir’s compact transmitter plugs directly into the MIDI output of any keyboard you wish to turn into a wireless controller. The
transmitter is battery powered and can operate at distances of up to 10 meters (30 feet) from the receiver. It is compliant with
the MIDI specification and will send virtually any command that your keyboard can generate.

Setting up wireless operation is simple. Just connect the MidAir transmitter to your existing keyboard, connect the receiver
to a MIDI module or your computer’s USB port and turn on your equipment. There are no complicated setup procedures or
software applications—your audio software treats your new wireless keyboard just like any other wired controller you may have
in your studio.

Whether you’re looking for unfettered live performance, or the flexibility to set up and record MIDI tracks anywhere in the studio,
MidAir is your wireless MIDI solution.

* MidAir is compatible with virtually all MIDI keyboards as well as other devices that have a MIDI output (such as drum
machines and control surfaces). To simplify this User Guide, we refer to all of these wired MIDI devices collectively as
“keyboards” but please keep in mind that this applies to other devices as well.

Internet access and some concert venues have switched to wireless microphones and in-ear monitoring systems. All of these
developments have improved the lives of end-users by reducing cabling clutter, allowing people to move about freely and work
more comfortably. MidAir technology extends this level of convenience to musicians working in the studio as well as performing
on stage.

MidAir establishes a one-way 2.4GHz wireless link and delivers a dependable MIDI connection at distances of up to 10 meters
(30 feet). This proprietary linking technology constantly monitors the wireless signal and automatically changes frequencies
when interference is detected, thereby ensuring a robust connection between the transmitter (keyboard) and the receiver. In
cases where extreme interference or battery failure cause the transmitter and receiver units to lose contact, a full MIDI reset
(including an all-notes-off “panic” message) is issued to prevent stuck MIDI notes. In short, MidAir frees you from your MIDI
cabling, allowing you to work from anywhere in your studio or on stage.

MidAir is class-compliant—no drivers are required. Simply connect the receiver to your Windows XP or Mac computer, attach
the MIDI breakout cable to the transmitter, connect the transmitter to your keyboard and you’re ready to go. Its simple USB
connectivity eliminates the need to open your computer to install hardware.

he MidAir receiver is class compliant. This means that on Windows XP and Mac OS X computers, you can simply connect
the receiver to the computer with a USB cable. The operating system already has the drivers required to communicate

T

with the receiver.

However, advanced Windows XP users who intend to use MidAir with more than one application at the same time or
simultaneously use other class-compliant USB devices with audio capabilities should install the special M-Audio drivers for
optimum performance.

Installation instructions can be found in the printed Quick Start Guide.

5. Power Switch – This switch powers the unit on and off. If both AC and battery power are available, the transmitter
will opt for AC power in order to preserve battery life. When not in use, be sure to turn off the transmitter to
preserve battery life.

6. MIDI Input Connector (MIDI)
– Attach the included MIDI breakout
cable to this jack and connect the 5­pin MIDI plug to your keyboard’s MIDI
output.

7. Wireless Connect Button
(Connect) – The MidAir transmitter
and receiver will usually establish a
wireless connection automatically.
Under some circumstances,
excessive interference, distance, or
other factors may cause the controller
and receiver units to lose contact. If
the wireless connection fails and the
transmitter and receiver are within a
range of 30 feet, press the wireless
connect buttons on both units to
re-establish connection.

If you’re using more than one MidAir wireless setup, you might find yourself in a situation where you’ve inadvertently

linked a transmitter to the wrong receiver unit. This will result in your MIDI data being routed to the wrong
destination. If this happens, you can simply press the wireless connect buttons on both devices to “re-introduce”
them to each other.

This button is recessed to avoid accidental activation. Use a bent paperclip, pen, or other small object to press the

here.

9. USB Connector – Connect a
USB cable from this output to
the host computer’s USB port.
When using the USB connection,
the receiver unit is powered via
the host computer and a power
adapter is not required.

10. MIDI In (In) – You can connect a MIDI device (such as a keyboard or electronic drum kit) to this input. Note
that this input varies in function depending on whether your MidAir setup is in standalone mode or connected to
a computer:

MidAir User Guide | 7

< Standalone mode – When used in standalone mode, either the wireless signal from the MidAir transmitter

or from the MIDI input is routed to the MIDI output port of the receiver. The Standalone Mode switch (15)
determines which source is routed.

< Host mode – When the receiver is used with a computer, the computer sees this port as a separate

USB MIDI device that is unrelated to the MidAir transmitter. Data received at this port is treated as an
independent MIDI input, and is not merged with incoming MIDI data from the transmitter.

11. MIDI Out (Out) – Connect this output to other MIDI devices using a standard 5-pin MIDI cable. The function of
this port varies depending on whether you are using the MidAir receiver in standalone mode or with a computer:

< Standalone mode – When operating in Standalone mode, the Standalone Mode switch (15) determines

the source of this output.

< Host mode – When the MidAir receiver is connected to a computer, this port appears as an independent

MIDI out, available for sending MIDI messages from your software to an external MIDI device. In Host mode,
this MIDI output port has no relation to the MidAir transmitter. In this setup, the Standalone Mode switch is
ignored and does not affect operation in any way.

12. Wireless Connect Button – This button operates in exactly the same way as the Wireless Connect button found
on the MidAir transmitter. See the description in the previous section for more information about this button.

13. Wireless Connection Status LED – This green LED functions in the same way as the Wireless Connection
Status LED found on the MidAir transmitter. Refer to the description in the previous section for more information
about this LED.

14. Activity LEDs – The MidAir receiver’s two activity LEDs indicate the operational status of the unit:

< Yellow – The yellow LED illuminates whenever incoming wireless MIDI data is detected by the receiver

unit.

< Red – The red LED illuminates whenever data is received at the wired, 5-pin MIDI input port on the

receiver.

15. Standalone Mode Switch – This switch only affects the signal routing when using MidAir as a standalone (non-
USB) device. It selects the source of the receiver’s MIDI output port.

The Standalone Mode switch can be set in the following three ways:

< MIDI In – Data from the receiver’s 5-pin MIDI In port is sent to its MIDI Out port. Any data received

from the wireless input is ignored.

< Wireless – Data from the receiver’s wireless input is sent to its MIDI Out port. Any data received

from the wired MIDI In port is ignored.

< Auto – The receiver monitors both the MIDI In port and wireless input and selects whichever input is

currently active. On this setting, the following rules are observed:

The wireless and 5-pin MIDI In port data streams are never merged—when MIDI data is being received from the

receiver’s MIDI In port, any data received at its wireless input is ignored.

If no MIDI data is received from the receiver’s wired MIDI In port for 250 milliseconds and incoming MIDI data is

detected at the wireless input, the receiver unit will automatically switch to output the incoming wireless MIDI data
stream.

If the receiver switches from one stream to another, a set of “Note Off” and other MIDI reset commands will be

sent to the MIDI Out port. This prevents any notes that are currently playing from becoming “stuck.”

IMPORTANT: If the Standalone Mode switch is set to “Auto,” it is important to plan your MIDI input sources

carefully. For example, if you attempt to drive a synth or other MIDI device by sending an ongoing stream of MIDI
data to the receiver’s wired MIDI In port (e.g. MIDI Time Code (MTC) from a sequencer), any MIDI data received
at the wireless MIDI input will be ignored.

Additionally, use caution when switching between the wireless input and the MIDI In port as this can sometimes

cause notes to stop abruptly.

MidAir can be used in two basic configurations. Please take a look at the scenarios outlined below to find the one that best
works for you.

Scenario 1: MidAir as a Wireless, Host-Based Controller

If you plan to use your MidAir system in a computer­based recording studio, this setup should best serve
your needs. In this configuration, the keyboard operates
wirelessly while the receiver communicates with the
keyboard and provides an extra set of wired MIDI inputs
and outputs to your computer. You can use these extra
inputs and outputs to connect another MIDI device in
your studio.

The MidAir transmitter can be powered by batteries or
the AC adapter. The wireless receiver draws its power
from the USB bus and does not require any AC power.

NOTE: In this configuration, your audio software will
detect two MidAir MIDI input ports and one MIDI
output. The first input is from your wireless MidAir
transmitter whereas the second input is the wired 5-pin
MIDI input (i.e., any MIDI device you connect to the 5­pin input). The output port lets you send out MIDI data
to any device that is connected to the MidAir receiver.

Scenario 2: MidAir as a Wireless, Standalone Controller

AC Adapter

MIDI

Receiver

Sound Module

IN

OUT

Transmitter

MIDI Controller or Keyboard

Live performers who want to use their MidAir system
wirelessly on stage will most likely use this scenario. In
this configuration, the MidAir transmitter (keyboard) sends
MIDI commands to the wireless receiver which then relays
that information (via MIDI cable) to sound modules or other
MIDI devices.

The wireless receiver must be powered by AC adapter
whereas the MidAir transmitter can be powered by either
batteries or AC power.

Note that in this configuration, the Standalone Mode
switch should be set to “Wireless” or “Auto” so that the
receiver will relay the MidAir transmitter’s commands out
of the MIDI output port.

MidAir User Guide | 10

The Standalone switch determines which input signal is routed to the MIDI output port. By setting the Standalone switch to
“Auto,” you can have a different MIDI controller connected to both MIDI inputs and use them subsequently without having to
change the cable configuration or Standalone switch position. Keep in mind that the MidAir receiver never merges signals from
the wired and wireless inputs. If MIDI is received on both the wired and wireless MIDI input port simultaneously, then the wired
MIDI input will take precedence while any signals received at the wireless MIDI input port will be ignored.

For more detailed information about the MidAir receiver’s routing operation, please see the Standalone Mode switch description
in chapter 7 of this guide.

MidAir is a professional-grade wireless MIDI system that has been tested under a wide variety of conditions. But in the event
that you experience difficulty with your MidAir system, this section covers some common issues and tips to remedy these
problems.

I’ve installed and set up all of the software correctly, but the MidAir receiver does not seem to be receiving any
data from the transmitter.

< The first time you use your MidAir system, you may need to press the Wireless Connect buttons on the MidAir

transmitter and receiver unit to allow the two units to establish a wireless link. Once a wireless connection is
established, the green Wireless Connect Status LEDs on the transmitter and receiver will illuminate, and you’re
ready to go.

My MidAir transmitter’s wireless range seems limited.

< Certain kinds of building materials and household items (i.e., thick walls, concrete, steel, microwave ovens,

cordless phones, etc.) can reduce or block the transmitter’s 2.4GHz radio-frequency transmission to the receiver.
For best results, place the receiver high above the ground in a location where it can be seen throughout the room.
By minimizing the physical obstructions between the transmitter and the receiver, you will maximize the wireless
range.

If you have a microwave oven or cordless phone within 10 feet of your MidAir transmitter or

receiver, try moving these items farther away to see if your wireless range improves.

I am using multiple MidAir products and my wireless keyboard seems to be linked to the wrong receiver.

< If you are using multiple wireless MIDI products, it may be possible to accidentally cross-link the wrong transmitter

and receiver units. To resolve this issue, simply press the Wireless Connect button on each transmitter and
receiver pair to allow the two units to establish a wireless link. Connect your wireless systems one at a time until
everything is linked properly.

MidAir User Guide | 12

My MidAir system suddenly stopped working after having worked well since installation.

< Switch off the transmitter and remove the power source from the receiver (USB or AA batteries) and leave them

powered off for 10 seconds. Restart your computer and try again.

My drivers are listed in the Device Manager and are said to be working, but the keyboard is not recognized in any
software.

< Windows XP has a limitation to how many MIDI device drivers you can have installed at any one time. Unfortunately,

the operating system does not indicate that you are using the maximum number of drivers. To fix this problem,
go to http://www.m-audio.com and search for this problem in the Knowledge Base. You will find a link to an
executable (.exe) file that will solve this problem for you.
