Martin what would be my best option to create soundesign for my film not using, cubase4 or protools. I understand I can use logic pro but will it work for film? thanks alexander

You could use almost any DAW, though you will need something that can open and sync to film, frame by frame. I personally use Logic for everything I score. It's video side has always worked well enough for me. Soundtrack Pro isn't really a very serious DAW, so I wouldn't suggest it.
