Hi,
I’ve got dozens of tracks in one song, and there’s a chance that the playback is not in sync even when the tracks are perfectly synced.
Scene 1: (Sometimes)
Play from the top and you hear a glitch in the silent bar. Then everything comes in, unsynced.
Scene 2: (Always)
The start is alright but if you jump to the middle, all the tracks become unsynced.
For your information, this problem never happens in Cubase. The buffer for the interface is set to the biggest number, and the whole computer is far from its performance peak.
