ofxMidi + midiOut on OSX?

(not sure if this is the right forum for this topic)

Hi - as a starting point for working with midi in oF I want to make a little midi player: take input from a keyboard or midi file and play it back using the OSX QT synth.

I have compiled and am able to run the ‘midiexample’ file that has been mention elsewhere on the forum. I am able to get input from the keyboard through this message function:

  
void testApp::newMessage(ofxMidiEventArgs &args){  
	int 	port;  
	int		channel;  
	int 	status;  
	int 	byteOne;  
	int 	byteTwo;  
	double 	timestamp;  
	  
	cout << "MIDI message [port: " << args.port << ", channel: " << args.channel << ", status: " << args.status << ", byteOne: " << args.byteOne << ", byteTwo: " << args.byteTwo << ", timestamp: " << args.timestamp << "]" << endl;  
  
// trying to rout the msg to midiOut:  
	if (args.byteTwo == 0){  
		midiOut.sendNoteOff(args.channel, args.byteOne, args.byteTwo);  
		cout << "off" << endl;  
  
	} else {  
		 midiOut.sendNoteOn(args.channel, args.byteOne, args.byteTwo);  
		cout << "on" << endl;  
	}  
}  

The msg info looks like this:

  
  
// start up code to list ports  
ofxMidiIn: 2 ports available   
0: IAC Driver IAC Bus 1  
1: USB Keystation 49e  
ofxMidiOut: 2 ports available   
0: IAC Driver IAC Bus 1  
1: USB Keystation 49e  
  
//msgs received from keyboard input  
MIDI message [port: 0, channel: 1, status: 144, byteOne: 41, byteTwo: 77, timestamp: 0]  
on  
MIDI message [port: 1101081088, channel: 1, status: 144, byteOne: 41, byteTwo: 0, timestamp: 0.143988]  
off  
MIDI message [port: 1107697408, channel: 1, status: 144, byteOne: 43, byteTwo: 41, timestamp: 11.8763]  
on  
MIDI message [port: 1101112576, channel: 1, status: 144, byteOne: 43, byteTwo: 0, timestamp: 0.14803]  

In the code above I am trying to route the msg to an instance of midiOut - but it is not resulting in any sound. Am I missing an additional lib or set up? Not getting any error msgs. I’m a little confused by the ‘port’ value changing for each incoming msg.

While I’m here - I will also want to play a midi file, so any tips on that would be helpful too.

Thanks!
