MIDI keyboards range from portable 25-key units that fit in your backpack to full-on 88-note keyboards with weighted keys. It’s important to remember that a MIDI recording is not an audio signal. Other advantages of MIDI include small file size and the ability to easily import and modify MIDI data in a variety of ways. A MIDI recording of a performance on a keyboard could sound like a piano or other keyboard.īut, since MIDI records the messages and information about notes and not the specific sounds, this recording could be changed to any other sound you’d like, based on whatever virtual instruments you have at your disposal. It’s as easy as changing the instrument on whichever track you’ve recorded MIDI data. When you play a MIDI controller, all of the key presses, button presses, knob turns, and slider changes are converted into MIDI data.Īs we described earlier, one of the most common applications is to play a MIDI keyboard to trigger a digital sound module to generate sounds. MIDI carries messages including a note’s notation, pitch, velocity, vibrato, panning, and clock signals (which set tempo). It was established in 1983, and not much has changed over the years!Ī single MIDI link through a MIDI cable can carry up to 16 channels of information, each of which can be routed to a separate device or instrument.
Short for Musical Instrument Digital Interface, MIDI is a standard which includes a communications protocol, digital interface, and physical connectors for different electronic instruments, computers, and other audio devices for playing, editing, and recording music.
