The reason I want to stick with Cakewalk is because I've been using it for a long time and I know how to play around well with it and how to connect the keyboard to it. I didn't like Fruity Loops or even Live because it was too confusing and I can't get full versions, only demos. And I like the idea of having a workstation and piano keys so I can rekord melody, etc.
I'm going to try Reason, and if I can use both S03 and Reason's synth and drums in one song (not one track as i said earlier, my mistake), it would be just great!
