Hosa Technology MID-310 Standard MIDI Cable Male to MIDI Male Cable 10' - Black New item. In original packaging. Musical Instrument Digital Interface (MIDI) The MIDI protocol allows communication between a computer and a digital 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 the basic tones. Discreet 5-Pin Connectors Each of the five pins on the connectors of these MIDI cables are wired to support all MIDI functions, including uploading and downloading data and relaying SysEx information. Cost-Conscious Design The injection-molded connector bodies with built-in strain relief are rugged and dependable, and the stranded copper conductors are surrounded by a dense copper shield to ensure long life and interference-resistant data transfer.
