Hello,
I have some instruments only as SE (have to economize for that), and used it for programming.
E.g I could transform from SE plus the trills in a vienna classic used manner (much faster), of course the strech generates in the loops automatically a slight different vibrato (to much strech makes it ugly though).
BUT the best thing is the programmable humanizer.Flute staccato starts in the real orchestra sometimes to high, due to the pressure.This random is now proogrammable, also a few different starting effects by 4 groups for typical strings repetition.I can now calculate and programm what I heard during my work as an orchestra musician.Of course you should sometimes visit an orchestra rehearsal while siting between the musicians to get an idea, how you will corrupt VI pro most effectively.To make now septoles groupes naturaly by only 2 samples (up, down bow) is now quite simple.Also the bowchanges can be erased where you wanted only the heavy down bow, by clicking on the second sample.
I had to write a fake Mozart Symphonie while my first tryout, and since then the last version sounds like stiff musicians with shockfrozen intonation while the audition for a job.
I wouldn't be in favor of using this tool for soundbanks that don't use as exact and acribic conected original recording data, it works only because the original samples are pure.
I use it in finale and in Logic and it works fine.
