Starting Cubase Artist 10 kills UR22 driver

Hi,

On Mac os 10.15.1 using Cubase Artist 10.0.50 and using Yamaha usb driver 1.10.5.

If i unplug the UR22 MK2 usb and plug it back in i can play back audio from the Mac no issues i.e. USB driver found and loaded and audio playback fine.

From a Mac POV - it appears i have 2 devices named Steinberg UR22mkII listed in settings>sound and one of them as type USB the other has no type.

If i navigate to Audio Midi setup i can see again 2 UR22’s listed - one showing the USB icon the other not.

Again if i set the UR22 with type USB to my desktop output sound i can playback sound from say you tube or itunes or even through finder… but as soon as i launch Cubase and is why i’ve chosen to place this thread in the cubase section rather than UR22 the listed device with type USB disappears and there is nothing i’ve been able to do to get output sound from that device using cubase.

If i change asio driver to built in i can hear cubase through internal audio.

When i unplug the usb there are no devices of steinberg UR22mkII listed …

I’ve tried uninstalling the driver and reinstalling following the install / uninstall process but nothing works.

It worked the other day and today i updated to the latest Mac 10.15 patch however i have been having issues since i updated to Catalina.

Do we know if there is a known issue with this latest update that maybe requires another Cubase/audio driver patch?

Could it be the fact there are two UR22mkII’s listed in devices potentially indicating the problem? even though it works when not loading cubase?

When i start cubase and it ‘kills’ the usb connected ur22mkII it prompts me for a driver to use - if i select the first option for UR22mkII I get a popup stating

“The audio driver could not be loaded. Please make sure your audio hardware is connected correctly to your computer”

If i try and unplug and plug back in when cubase is loaded it just dies immediately.

some Mac sys logs if anyone can understand them?

Hi,

JFYI, neither Cubase or Steinberg hardware doesn’t supper macOS 10.15 officially, yet. But thank you for your input.
