⭑ ⭑ ⭑ 🥁 Auto MIDI NOTE OFF 🥁 ⭑ ⭑ ⭑

This programm solves a common problem with certain e-drum sets which do not send any MIDI NOTE OFF command what make a note last for ever. Every note that is played will consume the total available polyphony and the DAW will not play any note from there on.

I have been confronted with this issue in Logic Pro X with the e-drum set Millenium HD-120

This programm adds to every MIDI NOTE ON command received from the target input device an additional MIDI NOTE OFF command
