Your keyboard not only creates midi files, but it can also read them and, if you play a midi file in your keyboard, the keyboard reproduces the music that is encoded in that file. When you record a song on your keyboard, you are creating a 'midi file', which is basically a file that captures the duration and volume of every note you play as well as the voice you are using. Your PSR or Tyros keyboard incorporates the above MIDI standard. This data can also be recorded into a hardware or software device called a sequencer, which can be used to edit the data and to play it back at a later time. These messages are sent to other devices where they control sound generation and other features. MIDI carries event messages that specify notation, pitch and velocity, control signals for parameters such as volume, vibrato, audio panning and cues, and clock signals that set and synchronize tempo between multiple devices. A single MIDI link can carry up to 16 channels of information.
