I was considering getting Adobe Audition, but what I want to know first - how advanced music can we create in it? Is it possible to create tracks as great as some soundtracks from movies? I know this may sound silly, as they are performed by professional orchester. But I was just wondering.
No. And they are rarely performed by a professional orchestra. Most are done with a sequencer and virtual instruments. Audition has basic sequencing functions, but it is not a full-featured sequencer. However, Audition supports ReWire, so you can run Reason though Audition and Reason can create what you want, if you invest in some good sound libraries.
However, of course, with the right hardware, Audition could certainly record a professional orchestra with stunning results.
