When you duplicate tracks in a project, they will not show up as an available track in the batch channel export window until you close and reload the project.
To see this for yourself:
Open any project (I’m using all instrument tracks)
Open the batch channel export window and take note of the tracks
Close the batch channel export window
Duplicate a couple tracks
Open the batch channel export window and those new tracks will not be there.
Are you forgetting to highlight the dupes? And, having not seen what you do, you might also just have to restart the Export dialog instead of rerun Cubase. (?)
Definitely a bug. I can reproduce it on 3 different Cubase 6.07 machines over here. It just sounds as though it was fixed in 6.5, which we haven’t paid to upgrade.
Here duplicated tracks appear at the bottom of the channel export list, not at the position the track has in the project windows/mixer (s. screenshot), unless I reload the project
Hmm… interesting. That may be the case. I’m dealing with about 150 tracks, so maybe I missed the tracks at the bottom. I’ll check that when I get to work tomorrow. Thanks!
