I am trying to mix a track in Sonar 8.5 that I made in Reason 5.0 and Fl Studio. The problem is that when I export the tracks from Reason they all match up. The Fl ones do too. But, in sonar, when I try to play all the tracks together they sound fine at first but fall off time slightly and alot toward the end. When I had the main backing track in FL ( which we recorded to) it was just the main export from Reason. Any ideas?
