Hi,
Are there any samples or tutorials available for writing an OS X MIDI driver
that communicates with an audio driver kext for a PCI card? I've looked at
the CoreAudio book, the MIDI docs in the latest CoreAudio SDK, the headers,
and the USB driver sample, but what I'm really looking for is a roadmap for
developing a MIDI driver, not just an explanation of what a particular MIDI
function does.
I've read that my MIDI driver/CFPlugin can communicate to my kext using the
IOKit, but I'm not sure if that means that I need to do that through a user
client or using something else. Also, I don't have an overall idea of how to
(correctly) design and implement an OS X MIDI driver, whereas the process
for developing kexts is pretty well documented. Finally, the interaction
between my plugin, the MIDIServer, and the rest of the OS (audio or
otherwise) seems to be a black box.
Can anyone point me to further samples or documentation that explains all of
this?
Thanks,
Dave
