The inclination towards smaller hardware devices has made it increasingly difficult to make use of DIN connectors for MIDI In/Out in the past few years. Many manufacturers have chosen to use 3.5mm "TRS" connectors instead.

This is a rack allowing you to convert MIDI DIN In or Out signals to MMA RP-054 compliant TRS 3.5 mm Midi type A, so you can "patch" midi in and out as you want with basic stereo cables.

3.5mm TRS cables are not provided.

NB : Prototypes are fully functional but can have track corrections due to routing errors during PCB design/fabrication. RED BATCH - LIMITED STOCK !

The board sold is the one with the blue arrow. An example is shown with the UMK4x4 board (the red arrow), not included.
