?! I mixed down 23 songs(sessions) for a hiphop mixtape over the weekend and 3 of the sessions would not bounce. Something about an 'Assertion'? I think it was in line 33. I'm still really frustrated not only because I had to send the sessions out to an Alesis Masterlink, but I also have no idea why those particular three sessions would not bounce. I'm using ProtoolsLE/002R on a 17in Powerbook G4 Mac laptop with 1gig ram. I bounced all of the sessions to .wav @ 16/44.1 as stereo-interleaved. This problem only occured once before- about four months ago- and I thought it was a fluke...guess not. I'm pretty damn lost and would be very grateful for any guidance in solving this problem. Thanks a lot. P.S. I also tried busing all of tracks through an aux(moving the master track effects to the aux track) to an audio track, on which I recorded a stereo mix. I closed the session and copied the resulting L and R tracks (I renamed them too) and imported them into a new session. I then unsuccessfully tried to bounce the new session. The results were the same for all three sessions.
