Hi,
Contrary to what the rest of this email may imply, I'm not a complete
idiot, I am, however, a complete novice to both Apples and CoreMIDI. My
colleague and I are trying to start a small project but we are stuck on
some elementary problems. Previous posts direct people's attention
towards the example echo.cpp, but, this application crashes whenever we
run it on our system.
The application crashes only when a midi keyboard is connected to the
system. I know the keyboard is continually sending out null midi
messages. To me this seems as though the IAC bus is acting as a
loopback device, and copying the output back to the input again
creating a huge queue of messages which are using all the systems
resources. Does the IAC bus act as a loopback device? If not can anyone
shed some light on our problem?
Secondly, I am still very confused about how messages can be moved from
destination to source. The example only shows how to connect several
sources to an input and send the messages to a destination. The only
thing I can think of is that, because sources and destinations are both
MIDIEndpointRef's that they may be used interchangeably, but this has
not worked either.
I am sure this question has been asked before, but I would be very
grateful if someone can lend an explanation or some example code, as
documentation for CoreMIDI seems surprisingly thin.
Cheers,
D McGilvray
