I just did some "runs" in the woodwinds section manually using the legato tool and they sound very very good. The reason being is that the performance is at the exact tempo with the exact number of notes. I switched between 4 and 5 sixteenth notes per beat at some points, which you could never do with a sampled run. (I have used sampled runs as well to good effect, but it's just not as controlled)
The fast way to do this is to play the run (at a slower tempo if you like - then switch to original faster tempo) in one instrument like flute, then edit velocities, durations, etc., and then copy the part into the other winds (or any other instruments like, strings.) You can also copy into lower range instruments than simply transpose. If it sounds to perfect "humanize" it a little. I find that since all instruments speak a little differently I rarely have to do anything but just copy and paste away.
Just my two cents (as us Yanks say)
