Ever since upgrading to Cubase 7.5 and OS X Mavericks, I’ve noticed that the “Audio Hardware Setup” option in the “Devices” drop down menu in Cubase disappears. This stops me from making any changes to the routing of my headphone mixes as it’s the only place (known to me) where I can assign which physical outputs the headphone outs mirror. Furthermore, upon quitting Cubase, any attempts at making these changes in the MR Editor are met with the following error (see screen shot below): “Cannot use IEEE 1394 port; it is being used by another application.”
The only way around this issue is to reboot the computer, and that’s only temporary as this bug occurs quite often. It may be the result of Cubase crashing on exit (which it does occasionally and has since version 6, though I think that’s due to Slate Digital’s FG-X), but I’m not sure of that. Has anyone experienced something similar? Is there a process I can quit and relaunch to regain control of the MR816 IEEE port without having to reboot?
Any help is greatly appreciated.
