Hi MIchael
I think I’ve seen what you’re referring to – this can happen when you have an empty track between already used tracks – eg: you have mono fx on track one, nothing on track 2 and stereo music on tracks 3&4. Sometimes, FCP will attempt to use that empty track 2 and the next empty track (track 5 in the above example) as the next available “pair”.
You can solve this by creating new audio tracks, and dragging your errant audio down to them. If it has lost the stereo linkage, you can rejoin it by using the ‘make stereo pair’ command (default keystroke alt+L ) to rejoin the tracks. I would suggest that when you put new audio into the timeline you drag audio to the correct tracks, and make sure you assign stereo audio to an odd/even pair (eg. 1/2 or 3/4 etc).
All the pan and track assign options can be seen in the audio mixer.
Hope this helps.
