What is MIDI?

Language of communications protocolTransfers messages about musical notation, pitch (position, example: E4, C4, etc), velocity control signals for parameters such as volume, vibrato, audio panning, cues, and clock signals Data of instructions, not audioHas no sound

What do you record in MIDI?

Recording the performanceInformation or data that use numbers from 0-127Instructions

velocity?duration?position?when did it "note off"?patch?expression? (damper pedal/sustain, pitch bend, mod wheel, volume change)

Control or automationMIDI word: 10 bits per byteMessages

Channel - any messages specific to a track; patchSystem - for all tracks; tempo, meter, key signatureSystem Exclusive - for hardware

What are the different files of MIDI?

General MIDI (GM1 and 2): 001-127Formats: .mid/.smf (standard MIDI file: any MIDI programs can read this format), .kar (MIDI Karaoke, audio video [for the lyrics]), .xmi (Extended MIDI: used for games)

What are the hardware used in MIDI?

InterfaceMIDI ports (In - receive, Out - send, Thru - repeater) - chain In to Comp and Out to Synth - loop ==>> to hear, audio out

if patch used is from comp, then audio out is connected to computerif patch used is from synth, then audio out is connected to synth

Master and Slave(Controller) Master - produces the out dataSlave - follows master
