When more than 21 outputs are defined in Cubase > Studio > Audio Connections… > Outputs, the Output Routing menu in the Project window shows duplicate entries for all buses with multiple outputs. Reducing outputs to 21 or fewer restores normal operation.
- Create an empty project
- Add an audio track
- Navigate to Studio > Audio Connections… > Outputs
- Add buses until the total number of output channels is 22 or more
- In the Project window, click the Output Routing drop-down in the Inspector for the previously added audio track
- Note duplicate entries in drop-down menu
I’m using Cubase v9.5.10 Build 97 (64 bit) on Windows 10 Professional.
Attached are screen captures demonstrating the problem.
