A new specification from the MIDI Manufacturers Association outlines how to use jack connections with your MIDI devices.

The MIDI Manufacturers Association (MMA) have released a guideline for using TRS Connectors instead of DIN connectors for MIDI In/Outs. TRS connectors which include many jack connectors are far more widespread and common than the MIDI standard 5-pin DIN connectors so the new specification will be great news for many MIDI lovers.

The MMA explain how you can wire TRS (tip-ring-sleeve) connectors for use with MIDI devices using the correct device circuitry and cable specifications that will allow the TRS connection to support MIDI signals. MIDI connections have been slowly going out of fashion as musicians and manufacturers opt for smaller connections allowing for more compact designs.

With the increase of 2.5mm and 2.5mm TRS connections on new devices the MMA have decided to release an official specification to allow all MIDI devices the same opportunities with a little wiring. They say: “By specifying the pin-out for the TRS connection, and also the connectors for the adaptor cable, we can ensure greater interoperability between TRS and DIN-MIDI devices.”
