Petrucci, Nolly, Plini, Rabea, and Soldano are all “X” versions now.

Mesa Mark IIC+ Suite has not been updated to an X version (yet).

I wonder if that’s the difference. Maybe check the settings for audio interfaces within the plug-ins.

Okay, that makes sense. If you activate Line 1 and Line 2, you can choose either mono input or stereo input (which means it’s using Line 1 for left and Line 2 for right).

If you deactivate Line 2, there’s no point for the Input Mode slider to work, so it’s greyed out.

In either case, you can still get stereo _output_. No problems here.
