I'm using the command line
sendmidi to send midi from a reascript to a Windows system midi device Microsoft GS Wavetable Synth, Midi Mapper or Coolsoft VirtualMIDISynth.
Now with Mac how can I create a Virtual Midi Device to show in the device list to choose to send midi to. Can I create a virtual device that uses the Apple DLS Synth ? I get the Apple DLS Synth AUi in Reaper and thought I could load it into IL-MiniHost and use the IAC device but it don't show in there so not sure where the location is ?
