I just use a lot of fast legato passages in my music. And that's where samples really fail me. I have woodwinds covered, I can do playable Williams' runs no problem, but I need a brass library (preferably recorded in hall, i just like having that sound instead of close sample modeling) which can handle that.What's with the "fast legato" obsession? Why is that the most important thing for you? I would say that the general sound, expression, musicality and natural sounding legato is much more important.
