I can reproduce the following bug (Cubase 8.0.0 Build 418):
Tempo track AND Signature track disappeared from the main window.
If I try to add them, I get the following error message: “the project already contains a tempo track!” or “the project already contains a signature track!”.
You can edit both tracks in their dedicated tempo track editor window (cmd+T) and you can find both tracks in the project browser window, where you can both double click them and edit them. However there is no way to show them in the main track window.
This happens if the the project has been edited in Cubase AI7 Ver. 7.0.80 Build 2285.
- create new project in C8
- add tempo track and signature track
- open project to AI7
- open project again in C8 -> tempo and signature tracks are gone and cannot be retrieved.
Workaround: edit track in editor window, but it would be nice to see them again in the main window.
Can one confirm this?
