That's what they are made for. I orchestrate music by taking Styles from Biab turning them into midi and copying them into Cakewalk Sonar. Biab is a Historical program. It conveys a tremendous amount of musical knowledge and many times I will change the drum track to a midi drum-track and substitute in Komplete drums or Session but midi drums and it is amazing just by changing the drum set and tempo how the same song peaks different moods. Then I will analyze what the motion suggests by using a book Tarthang Talku Time Space and Knowledge to help me clarify what I am witnessing. Realtracks sound good but you are working with an expected sound. Which is the opposite of what I am trying to do.
