#Use of sonarworks reference 4 with logic pro x mac
So that is the problem and here is the solution to how we control system level volume when we want to use an output other than the inbuilt Mac audio output. It isn’t the end of the world but I have always found it to be a slight irritation and consequently had always set my Mac’s system output to go out of the default output and then either auxed them into the audio interface I was using or patched into a monitor controller than can monitor more than one source at once, which is a feature you don’t find on many of the high-end monitor controllers as it can compromise audio performance. I’ve never understood why macOS limits the use of these buttons to only the inbuilt audio device, one which doesn’t usually have close to the audio performance of our dedicated, professional-quality audio interfaces. I don’t know about you but I usually want to hear this audio through my studio monitors but I also want to be able to control the mute/volume using the F10, F11 and F12 keys. It is not just the Grace that is affected, it is the same for any device that isn’t the inbuilt audio device of your Mac.
You can see in this screenshot that I am using my Grace M905 Monitor Controller for macOS audio output, but by doing this means that I lose the use of those Mac keyboard keys when the Grace monitor controller is selected.
Pressing the volume up/down or mute on the keyboard doesn’t do anything.
