Reference Documents
The SOURCE provides the power, whether 3.3v or 5v, to power an LED in the optocoupler in the receiving device, while the SINK pulls that power to ground whenever there is data to be transmitted. DIN MIDI Connector In the good old DIN5 MIDI Connectors, 3 out of the 5 pins are used. Pin 2 is used as GROUND, Pin 4 is used as the current SOURCE, while Pin 5 is used as the current SINK. Type A The Type A TRS connection is the official standard adopted by the MIDI Association. The Tip is the Sink (pulls the data line down) and the Ring is the Source.
