Blue Air is an infrared MIDI controller that measures distance. Continuous controller information is produced by movement an object or a performer’s hand vertically above the infrared eye located on the top panel of Blue Air. MIDI data produced by Blue Air are fast and tightly packed together. The typical time between blocks of MIDI datum is 5 milliseconds. The tremendous volume of data being sent is often best managed by MIDI manipulation software such as MAX by Cycling ’74.
