[0;16384] - divide by 16384 to make it compatible with ControlSpec.

It's a port number assigned by the OS. If you have a multiport interface, each midi cable gets a different uid. You can get the destinations by:

MIDIClient.destinations.do({ |midi| [midi.device, midi.name, midi.uid].postln });
MIDIClient.sources.do...  // for sources

I'm not familiar with the c++ sources, but InitMIDI should have the outports available to it.

	*prInit { arg inports, outports;
_InitMIDI
^this.primitiveFailed
}

Sounds like a bug to me.
