This means pins 1 and 3 aren’t needed and thus not wired. Standard MIDI cables are wired with pins 4 and 5 carrying the current, and pin 2 being used for the shielding to ground the cable. MIDI simplifies commands and is an easy organizational tool for professionals of all types.
Whether it’s from a guitar amplifier to a channel switcher, or an electric keyboard to an audio interface, the same cable serves both equally. MIDI is a universally used and recognized format, making the same MIDI cable functional for uses across all corners of musical equipment. That data can then be transferred to a computer and played the same exact way through another MIDI instrument.
Every time a musician plays a MIDI instrument, the performance is transmitted into MIDI data. For example, if a chord progression is laid down via MIDI, those same chords’ notes, velocity, vibrato, panning, tempo, and pitch can be transmitted to an instrument that has MIDI capabilities. MIDI, which stands for Musical Instrument Digital Interface, isn’t a sound or instrument, it carries digital instructions to recreate the music.
