Cubase 13 and Steinberg UR-RT2 – Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) Forum

I’ve had my Steinberg UR-RT2 interface & Cubase for some time and have used all the ports for various bus inputs..

Today however I find that although line 3 & 4 show as active within “Audio Devices” in Cubase 13, when I go to “Audio Connections” and “Add Bus” it only gives me a mono or stereo option and stereo option just creates a bus with inputs 1 & 2 and I can’t change them.

Additional: I’ve now checked using Bitwig. That is seeing Line 3 & 4 and I can add a bus using those, so the URT-RT2 is fine, it’s Cubase..

Any ideas?
