Abstract Some user agents have music devices, such as synthesizers, keyboard and other controllers, and drum machines connected to their host computer or device. The widely adopted Musical Instrument Digital Interface (MIDI) protocol enables electronic musical instruments, controllers and computers to communicate and synchronize with each other. MIDI does not transmit audio signals: instead, it sends event messages about musical notes, controller signals for parameters such as volume, vibrato and panning, cues and clock signals to set the tempo, and system-specific MIDI communications (e.g. to remotely store synthesizer-specific patch data).
