Multi-out / Stereo option: Multi-out does not work!

When you select more than two output channels then the option in question appears but Multi-out works like Stereo. Instead, it should work with a mono/stereo sound rotation scheme like you can do with Hauptwerk. I think there is a bug.

This is the description of the function
"If more than two output channels are enabled, this button toggles between 'multi-out', where all output channels are distinct, and 'stereo', where the extra channels are just a copy of the first two channels."
