I have situations where I have a montage set to Multichannel Free Configuration, with multiple tracks each assigned to a different stereo output pair (1/2, 3/4, 5/6, 7/8).
Later, I convert the montage to a Stereo/CD compatible configuration and assign all tracks to Lf/Rf. However, the apply button never becomes operable, remains greyed out. Even after I change all the tracks to Lf/Rf, the Audio Properties of the Montage does not always switch over. I have to try closing and reopening the montage: still multichannel … sometimes quitting and restarting WL…still multichannel, repeat… … … Well, eventually, for whatever reason, a gear finally drops into place and the Montage finally settles in Stereo mode. Don’t know why this does not just lock in right away or why the APPLY button never becomes active. The issue exists going the other way: stereo to multichannel.
Maybe I’m doing something wrong, but I feel I have tried every permutation of this. Has been happening since 9.1, now on latest version.
