Knowra MIDI MIDI MIDI is a digital communication standard for exchanging musical performance and control data among instruments, computers, and controllers. It transmits instructions such as note events rather than recorded audio.
MIDI message : A structured unit of MIDI data that communicates an event or control change. Messages carry actions such as playing a note or moving a control.
Digital audio : Sound represented as a sequence of numerical samples. Unlike digital audio, MIDI specifies performance events rather than sound samples.
Digital audio workstation : Software for recording, editing, arranging, and mixing audio and MIDI. DAWs record, edit, and route MIDI alongside audio.
Dave Smith : An American synthesizer designer who helped develop the MIDI standard and founded Sequential Circuits. Smith proposed a common interface for connecting synthesizers.
Open Sound Control : A network-oriented protocol for communication among computers, synthesizers, and other multimedia devices. OSC offers flexible network messaging where MIDI's traditional format is more constrained.
MIDI note-on message : A MIDI message that starts a note and specifies its pitch and velocity. It encodes the beginning and force of a performed note.
Musical note : A discrete musical sound characterized by properties such as pitch, duration, and loudness. MIDI encodes note events that describe musical notes.
MIDI sequencer : A device or software system that records, edits, and plays timed MIDI events. Sequencers arrange MIDI performances for playback and revision.
Ikutaro Kakehashi : A Japanese electronic-instrument entrepreneur who founded Roland and helped advance MIDI's adoption. Kakehashi helped bring competing manufacturers behind a shared standard.
Audio over Ethernet : The transmission of digital audio over Ethernet networks using protocols designed for real-time media. It transports sound itself, unlike MIDI's performance instructions.
