Particularly, in a context of pop song writer, I'm wondering if all the phrases are really playable in the sense that (even if there is a large variety of phrases) if we can find exactly the motif which will follow your own melody. Maybe it's more aimed at intros, bridges, riffs, some transitions.. but for accompanying the proper harmony of a specific composition, it could be rather tricky.
And precisely, if considering the runs, scales, rips... are maybe the most "useful" part, does Cinestrings Runs from Cinesample represent maybe a better alternative ( better Sounds, functionalities...) ?
