After many tests I decided to purchase it: I am very happy because the tool is way better than SC2!
My first concern was about my new workflow that is totally different from the old one, but I realized that CS3, both used with my old SC2 workflow or in new ways, works very well for backing tracks
Nevertheless, it works better with a pianoforte than an organ/synth and I’ll try to explain why, later in the Feature request page
Great job @davide& Co.
