MIDI - Musical Instrument Digital Interface first introduced in 1983 not software or hardware, more a universal "digital language", means of communication for music technology, code language instruments work with computers / each other 01011011 -> bytes (digital words) -> messages (note on/off, not number) MIDI consists of performance infromation - like print music MIDI is completely independent of audio - it is NOT sound tells something else when and when not to use a sound velocity measured 0 to 127 one keyboard functions as a controller, connected to another synthesizer MIDI doesn't transmit audio sound transmits info provided by the performer what key is pressed and when, what pedals are pressed, etc

All messages: Note on Note off Program change (go from one sound to the next) Pitch Bend Controller Change Pressure (polyphonic) Pressure (monophonic)

Midi Devices have three sockets Midi In: recieves midi info Midi out: transmits midi info midi thru: repeats the same midi in signal

useing thru, more than one instrument can be controlled by a single midi output Master instrument: instrument that sends info Slave instrument: instrument that receives info

Midi interface: device used to connect midi to computer translates midi data into a computer's own machine language

Midi OX - software emulator, allows you to connect multiple devices together through the computer itself Data range for on/off messages between 0-127 Middle C is 60

Aftertouch - can detect a note being pressed harder after it is pressed

Most synths have two functions - performance mode and multi-timbre mode Multi-timbre - more than one sound is being played Performance mode plays one sound

General MIDI synthesizer: for every patch that a synth makes, it will be the same for every synth First 8 are piano

Turning local control off Disconnects an electronic keyboard from its internal sound generator necessary when using a software or dedicated sequencer

16 MIDI channels, 10 is special mutli-timbre instruments can play on many channels at once 10 is the universal percussion and drum channel

MIDI benefits: small file size tempo and pitch are completely independent of each other Find sections using measures and specific beats performance and notation of a song (finale)

Sequencing: record midi data, plays back notes, a digital "piano player" similar to a multitrack recorder may also include digital audio recording
