Hi All, As the original poster I want to thank all who responded. Between responses to my inquiry and the Logic 5 introduction (manual, sort of). I got the information I needed to do what I needed. The project is moving ahead smoothly now. In researching this I find that Logic's way of managing the audio environment is to say the least,... funky. I was redoing an earlier project that had some mono tracks and I was redoing it with stereo samples and needed stereo tracks. The earlier project used about 20 tracks so as I started to add stereo channels I quickly ran out. I found I couldn't delete the mono audio tracks and create a stereo track using the same audio channel (e.g. track 8). Once I changed the preference to 48 tracks I could create audio objects and assign them to track 25 and it would work perfectly. Because I was able to do what I wanted I haven't checked whether deleting all audio from the audio window associated with track 8 would allow me to recreate it as a stereo track. It's a moot point at this point, because it's fixed and I'm back to makin music! Steve Chandler http://www.mp3.com/stevechandler
