Realband 2012 Build 5

Song goes 87 bars. Three tracks of audio that start at bar 1 and go to bar 85. I want to add a volume swell at bar 83. I open the piano roll and it won't go past bar 74 on any of the 3 audio tracks. I opened the event list and it shows audio, for each track, ending at bars 65,71, and 41, even though audio plays from bar 1 to bar 85. These are all realtracks that were generated in 8 bar segments. I'm stumped...Bobby
