Now these devices may be used in Airplane Mode.. In an effort to allow users to use functions on their phones that don't require wireless access while in flight, phone manufacturers have developed Airplane Mode to shut down all the phone's wireless capabilities.
Protocol Overview MIDI (Musical Instrument Digital Interface) is an industry-standard protocol that enables electronic musical instruments, computers, and other equipment to communicate, control, and synchronize with each other. MIDI allows computers, synthesizers, MIDI controllers, sound cards, samplers and drum machines to control one another, and to exchange system data.1 MIDI messages are sent serially, and are organized into 10-bit words.
MIDI is a protocol that was developed so that electronic instruments could communicate with each other as well as computers and other electronic devices. Through MIDI, a variety of musical information can be transmitted. MIDI is not only used to indicate what note is played, but the duration of the note, the velocity/volume, and sometimes the aftertouch or other information as well. MIDI is also used to transmit non-note information such as pan, effects, track or overall volume, and the like. In essence, MIDI is a basic communications protocol used by musical instruments and computers, much like Firewire is a protocol for computers and peripheral devices like hard drives, scanners, and camcorders.
