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.
The MIDI protocol was conceived as a device control protocol, like the Postscript or PCL protocol that sends data from a desktop computer to its printer. Today's word processing applications don't make the user edit printer data. Yet today's music sequencers are very much bound up in the MIDI protocol.
