OK, now it's stopped doing it! Hmmm...puzzling.
A bit more info:
Previously when I ran this app, the light on my UM-1 would go on and
stay on after the app had quit. Running the app again would cause a 2
second pause and the light would sometimes go off and come back on again.
Now that everything is working, the app runs instantly and the UM-1
light flicks on for a moment and then off again as soon as the app exits.
*scratches head*
Oh well.

I have an extremely complex MIDI application:
#include <stdio.h>
#include <CoreMIDI/CoreMIDI.h>
int main (int argc, const char* argv[])
{
printf ("%d\n", (int)MIDIGetNumberOfSources());
return 0;
}
and here is what happens when I run it a dozen times in a row:
% ./MIDIBug
0
% ./MIDIBug
1
% ./MIDIBug
0
% ./MIDIBug
1
% ./MIDIBug
0
% ./MIDIBug
1
% ./MIDIBug
0
% ./MIDIBug
0
% ./MIDIBug
0
% ./MIDIBug
1
% ./MIDIBug
0
Now can anybody explain to me why I don't always get a result of 1,
given I have one source available at all times?
I'm running a Roland UM-1 with Roland's drivers. I'll do some more
testing and follow up if I find anything more.
