The MIDI protocol allows communication between a computer and a digitally controlled synthesizer (keyboard, drum machine, etc.) by transmitting how the notes are to be produced. For example, commands like note-on, note-off, pitch-shift, and tempo create much smaller files and more realistic music, relying on the synthesizer to create all audible sounds.

This nonserviceable cable features durable, nickel-plated connector bodies, and the stranded copper conductors are surrounded by a dense copper shield to ensure interference-resistant data transfer.

Each of the five pins on the connectors of these MIDI cables is wired to support all MIDI functions, including uploading and downloading data and relaying SysEx information.
