1. What are the main differences between BeatCreator and TrackCreator? 2. What features does BeatCreator have that TrackCreator does not have? 3. If I buy TrackCreator first, can I later Upgrade to BeatCreator? 4. Why would I need to turn my Wav files into TRK files? 5. I have never sliced up audio files before, is it hard? 6. Can I import REX1 files, and just save them out to TRK? 7. Can I make my own Soundisc? 8. Is there any kind of documentation or tutorial for BC and TC?
