MIDI over DIN – in/out circuit
In Dart controllers, the MIDI_over_USB communication is always active, this allows the controllers to be used very often with the computer, but in many cases it may be necessary to have the classic MIDI over DIN connections.
Enabling MIDI communication through the classic 5-pin DIN connectors requires the assembly of a special circuit, described below.
