Hi Herbie,

Thanxs for your detailed answer.

I'm trying to get some output to the console so i wrote the following line in the MatchDevice function, before the return:

printf("Im here");

Then i started an application named MIDI Monitor which by its turn opens the MIDI server process.

I was waiting to see this line in the Console.log or System.log using the Console application, but no.

I didnt understand very well what you meant with the following sentence:

Be forewarned that you can't do printfs from the I/O callbacks because they happen on real-time threads and doing printfs will mess things up royally. 

What do you mean with this? That it will be confusing? Or that i will not see it actually.

About using XCode and the debugger, there was already someone in this list which suggested me the same but still didnt understand what can i do with that.

Are you talking in plug in the XCode to the MIDI server and then attach the driver i'm making thru XCode?!?

I believe that i only need to see what i am doing (see the debugging output), after that it will only be a question of time.


Many Thx,

Best regards,

Nuno
