I think there might be a problem with the Mac CI2+ driver. I created an aggregated device containing my new CI2+ and my iMac’s built in microphone and line in/out. This kept causing Cubase to crash when I tried to change the bus settings.
I also tried the aggregate device in Ableton Live and it crashed that too. If I remove the CI2+ device from the aggregate, everything works perfectly.
I tried re-installing the latest driver but it did not make any difference.
Is this a known issue? Is there a work around?
