The console routing for this project includes: Session Drummer Stereo Output 1 Channel>Mix 1 Bus>Master Bus>Audio Interface Session Drummer Stereo Output 2 Channel>Master Bus>Audio Interface When I open the project I get a warning that SD Output 1 is assigned to a silent hardware output. I can verify by soloing and listening that the assignments are correct. This happens in both X1 and X2.

Probably a bus/ output set to 'none'.

You can disable the silent busses warning in the Cakewalk. ini
file.
Changing this to "0" will disable the silent bus warning dialog.
