- Thread-topic: MIDI USB Class driver problem from reset
We have a USB audio/MIDI device that is using our custom audio driver but is
trying to use the Apple MIDI Class driver.
The problem is that the hardware needs to be reset when some sample rate
changes happen (which is part of the reason for our custom driver).
This reset appears to confuse the Apple MIDI Class driver to the point where
it stops working. Once you quit all applications that have an open
connection to the MIDI class driver and then open them again, MIDI starts
working again.
Is there some call that we can make from the audio driver to the MIDI driver
to tell it to reset? Is there some other way, aside from removing the
reset, that might be able to mitigate this issue?
Thanks,
Mark
