I recently bought a mac and I love it. However, I used to use a Vaio that I had Sonic Stage Master Studio. I prefer to make my own ringtones and I cut tracks to load into my blogs and webpages. How can I do that with GarageBand? I see where I can load something from iTunes and how I can cut each section, but how can I make that a master track without someother musical overlay? I just want to make a 30sec ringtone! Should I just give up and purchase Toast?
