I've done my own test with Chamber Strings (Gigastudio version).
www.Members.aol.com/jbacal/Chamber_Strings_legato_test.mp3 The test has the following short scale examples:
1) VI-6 perf-leg slow (out of the box-dry)
2) VI-6 perf-leg fast (out of the box-dry)
3) VI-6 perf-leg fast + VI perf-leg f mixed at 70% (out of the box-dry)
4) VI-6 perf-leg fast _2Lay + VI perf-leg p+f_2Lay mixed at 70% (I ramped the modwheel control from 0 to 127 and then back to 0. I also ramped the expression control on the last note from 127 to 0)
5) same as #4 but with a touch of Pantheon medium hall reverb.
All these examples sound noticeably smoother than Trip's example. The only way I could replicate his sound was to use the VI-6 perf-leg slow+RC instrument with the Modwheel all the way at 0. This puts the release time at .1 seconds. A more normal release time is .3 seconds. I don't know how the Kontakt version handles release times but if you can set them to .3 seconds you'll be a lot happier.
Please note that one additional thing you can do to smooth things out even more is to lower the velocity of the notes that have a more pronounced "bump." I didn't do this on these examples here, but it can make a big difference.
Hope this sheds a little more light on things.
Best,
Jay
