Dimension Brass is a genuinely revolutionary way to record brass samples and deal with the biggest problem in orchestra sampling - solo vs. ensemble. It allows you to simply concentrate on the music, exactly like writing down a score, instead of worrying about phasing, solo timbre vs. ensemble, which trumpet am I on? is this 3 horns or 4? etc. etc. You can just freely use all four players, or two, or three, or solo.
The current string libraries of VSL already are superior to other libraries because of the wide ranging articulations across Solo, Chamber, Orchestral and Appassionata, the playing/recording quality, and the methodical organization of all samples in a uniform manner within the elegant structure of VE. However, I would say it is very likely the same great approach of Dimension Brass could be used with strings to change the way divisi and ensemble are done and to add even more espressivo variations. It would certainly make VSL obliterate all string library challengers the day it was released, because with MIR, the VE interface is so superior to others for orchestral purposes.
