MIDI enables the user to receive, transmit, store and edit electronically produced signals that correspond to several aspects of music. Main parameters of these aspects include note-on, note-off, velocity, timbre and pitch. All these parameters can be stored as code in timeline fashion within a MIDI file. A MIDI file resembles the “program” in the form of a revolving cylinder or perforated paper used in late 18th c. music boxes or early 20th c. “pianolas”, which are musical automata. It is this characteristic that can be proved enormously useful for educational purposes, as numerous midi applications, sensors and programs are widely spread throughout the internet. However, it is the ability to edit the output as a musical score or as a part of a polyphonic composition that makes MIDI an exceptionally powerful educational tool. Within the present WIKI pages sensors using MIDI in particular, are widely displayed.
