I have found a simple solution with the MidiList object:

When a Note On command comes in, then in a MidiList the index of the pressed key is set to the value of the note that is output. e.g. I press key 60 which is not active but only the next key so "60 -> 61" is stored in the MidiList. When a Note Off command comes in, before the Note Off command is sent, it is first checked whether another key also has this value If no key has this value, a Note Off command is sent for the note and the key is set to -1 in the MidiList. If one or more keys have this value, the NoteOff command is not sent

onInit()

reg midiKeyList = Engine.createMidiList();

onNoteOn()

const receivedNote = Message.getNoteNumber(); var outputNote = getOutputNoteBySnapMode(receivedNote); midiKeyList.setValue(receivedNote, outputNote); sendNoteToMidiOut(outputNote);

onNoteOff()

const receivedNote = Message.getNoteNumber(); var outputNote = getOutputNoteBySnapMode(receivedNote); midiKeyList.setValue(receivedNote, -1); // set pressed Note in midiList to -1 if (midiKeyList.getValueAmount(outputNote) <= 0) { sendNoteToMidiOut(outputNote); }

I hope you can understand it.
Thanks guys

then there's nothing you can do about it, right?

Open an issue on the github page and link to this thread.

@WillDevelop Ok I see,
