I'm trying to bounce a few parts of a song I am working on from MIDI. So I solo the appropriate channels and on command it starts to bounce. Then at the end of the playback I get the error message, "Could not complete the "Bounce to Disk..." command because: Assertion in "FF_AudioProperty.cpp", line 33. I'm using Pro Tools LE 6.4 on MacOS 10.3.7. I'm using an iBook and MBox. Can anyone help me solve this issue?
