Ben, This is different than the MIDI export problem I wrote about last night. I thought I'd troubleshoot my MIDI problem by exporting a stereo file from Doggiebox 2.0 and comparing it to the MIDI track in Pro Tools, but ran up against this: When I go to export, the window shows up with the Sample Rate set to 0 and the number of channels set as 3355443. When I switch the Sample Rate to any of the various settings, I'm told that "Approximately 4096.0 MB will be required" for the exported file, and thus not enough room on my hard drive. The same set of problems (and numbers) greet me when I try to do the multi-track export. I've also run into an issue similar to what Dave had reported when exporting a MIDI file - I can't get the export to save in certain folders, and now it seems to not want to save anywhere. Again, running OS 10.5.8 on a 2.5 Ghz Core 2 Duo MacBook Pro. Jack
