M-Audio is shipping the new MidAir ($149.95) wireless USB MIDI system and MidAir 37 ($299.95) wireless keyboard controller. Using wireless technology from Frontier Design Group, all MidAir devices operate in the 2.4GHz frequency band, enabling users to interface MIDI hardware and software at distances up to 30 feet with the same feel and response as a wired connection.
The MidAir MIDI transmitter and receiver system allow users to wirelessly transmit data from any device that outputs MIDI. Users can plug the battery-powered transmitter into a controller’s MIDI out port and connect the receiver to the MIDI in port on the receiving device. The MidAir receiver also includes a USB port and functions as a class-compliant 1×1 MIDI interface for connecting to a computer.
The MidAir 37 includes 37 velocity-sensitive keys, a three-digit LED, nine MIDI-assignable faders, eight MIDI-assignable knobs, mod and pitch-bend wheels, and sustain pedal input and button. The controller can be powered by standard batteries or the included 9-volt power supply.
