Well, at least I know it's not something I did wrong. Is there an easy, quick way to transfer all the audio and midi tracks to a new song, retaining all their positions, plugin info, etc., or must I do it the hard way?

Probably the original song doc was corrupted in some way. Other people on the list have also reported this error. All the best per boysen

Here's the solution I came up with... It seems that the *screenset* is corrupted when this occurs. Creating a new instance of the mix window within the corrupted screenset does not fix the problem. So... Go to a different screenset, open the mix window and verify that the missing tracks are present. Then copy the screenset, and paste it into the corrupted one. Then rearrange the windows to your liking. I have seen this bug crop up quite a bit, and interestingly, it always seems to be when I am using a small mix window linked to the arrange window, as others have reported. I doubt that it's related to the sound card. I'm using the Tascam US-428 with LAMP 4.7 on a G4 Powerbook with 384 megs of RAM and system 9.1. Blake Leyh
