trying to control an external midi device playing a midifile with SimpleMIDIFile in Supercollider on a macbook (OS 10.14.6) the signal is not routed to the selected midi out but instead the internal Apple DLS Music Device is responding to the midi messages:
x = SimpleMIDIFile.read(“a Direction”);
If I send noteOn everything is working without any problems:
m = MIDIOut.new(0);
Anybody knows what could be the problem? Do I have to define the midi channel somewhere else?
Thanks in advance fo any helps!
