1 Introduction Thank you for choosing the MidAir 25 or MidAir 37 wireless MIDI controller. MidAir 25/37 combines a powerful MIDI controller keyboard with a high-performance wireless linking system.
About MidAir Wireless devices have become increasingly commonplace over the last few years. For example, many people now use wireless keyboards and mice with their computers. Lots of college campuses and coffee shops offer wireless 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.
7 Controls and Connectors Keyboard The MidAir 25 and 37 keyboards are identical except that the MidAir 37 contains an addition octave of keys and 9 MIDI control sliders. For identification purposes, the MidAir 37 keyboard is shown below: 1. Pitch Bend Wheel (Pitch) – This wheel lets you create expressive changes in your performances by raising and lowering pitch. Rolling the Pitch Bend wheel upward will raise an instrument’s pitch whereas rolling it downward will lower the pitch.
4. Wireless Connection Status LED (Connect) – This green LED displays the current state of the wireless link: < On – Connected < Off – Not connected < Blinking – Connection in progress 5. Octave Up/Down, Preset Select Buttons (Down, Up) – The Octave up/down buttons select the octave range of the keyboard. Press both buttons simultaneously to center the keyboard. The MidAir keyboard can store 10 presets in memory.
16. Power Switch – This switch powers the unit on and off. If both AC and battery power are available, the keyboard will opt for AC power in order to preserve battery life. When not in use, be sure to turn off the unit to preserve battery life. 17. Power Jack (DC in 9V) – Connect the optional 9V DC, 500mA external power supply to this jack. 18. Battery Compartment (on bottom) – Accommodates six AA batteries.To avoid damage to the keyboard, observe proper polarity when inserting batteries.
7. Activity LEDs – The MidAir receiver’s three 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. Note: When you are in Standalone mode, only the active input source’s LED will illuminate. In other words, only the yellow or red LED can be on at any given time.
8 Hardware Connections MidAir can be used in three 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.
Scenario 3: MidAir as a Wired, Standalone Controller If you are using your MidAir keyboard as a wired, standalone controller, simply use a MIDI cable to connect the keyboard’s MIDI Out to the input of another device (such as a sound module) and you’re ready to go. The keyboard can be powered by batteries or the AC adapter and the wireless receiver is not required in this configuration.
Program Mode Overview < The MidAir keyboard has two modes of operation: Program mode and Performance mode. Most of the time, the controller stays in Performance mode so you can play regularly—Program mode is only used when you need to configure various parameters like knob assignments. Use the MIDI Select button to enter and exit Program mode. < Once you have entered Program mode, you can select different parameters to edit by pressing one of the keys on the left half of the keyboard.
Programming the MIDI Controller Knobs The MIDI Controller knobs can be reassigned by doing the following: 1. Press the MIDI Select button. 2. Press the Set CTRL key. The display will show a small “n” to indicate that the desired Controller knob “number” should be entered next. 3. Choose the number of the desired Controller knob using the 0-9 keys. Then press the Enter key. The display will show a “P” in anticipation of the “parameter” number. 4.
Setting the Data Entry Slider By default, the Data Entry slider is set to control volume (MIDI Continuous Controller #7), but it can also be used to send MIDI controller information for pan, aftertouch, reverb depth or to set a velocity offset. You can reassign this slider by doing the following: 1. Press the MIDI Select button. 2. Use the labels above the keys to locate the parameter you’d like to assign to the Data Entry slider. Press the corresponding key to assign this parameter to the slider.
Other Functions in Program Mode All notes off: Pressing the MIDI Select button followed by the Reset key will send an “All Notes Off” message on all channels and will return all external MIDI instruments to their default settings. This function is known as the “panic button” and is useful if you experience stuck notes on a MIDI instrument. Once you have completed this action, press the MIDI Select button again to exit Program Mode.
10 Troubleshooting 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 keyboard, 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 keyboard.

Appendix C: Useful MIDI Data Tables C1 - General MIDI Instruments – Program Change Numbers The following table lists all General MIDI patch names using numbers from 1 – 128. Please be advised that some GM modules count their sound patches from 0 – 127 instead. Both methods are common. As a result, and depending on the sound module you use, there may be an offset of -1 between the sent program change number and the recalled sound patch.
