I have a project with multiple audio layers - a documentary with a running v/o, music and occasionally ambient noise. When playing back in the timeline, if there is a moment where v/o, music and ambient are all present at once, sometimes it plays back all 3 and sometimes the music cuts out. There seems to be no consistency in this occurrence, as all music is on 1&2, v/o on 3&4 and ambient on 5&6, and it happens at different parts in the timeline (i.e. there is no pattern to them cutting out, such as all in the second half of the film)
There is no red bar on my timeline indicating any further need for rendering.
I have tried both Safe and Unlimited RT - no difference.
I'm on FCP6
Mac Book Pro with 4gb RAM
Any thoughts or suggestions on this would be massively appreciated, cheers! Tali
