I don't consider myself a power user of the library, but certainly a power composer by comparison with what's around today. I am happy to read about another composer that is not just interested in lobotomotive music and wishes to exploit all nuances of the incredible VSL, and I personally wish they would record many more instruments and articulations - and I wholeheartedly agree, first of all they should certainly bite the bullet and make a completely separate Violin II and Solo Violin II sections/pleyer. Combining Orchestral with Appassionata Strings, or using different articulations, EQ etc. as Andi suggested, may get some results, but it really is a poor man's substitute; not what the flagship of sample libraries should be about...
However, and to my knowledge, VSL is the only library with so many demos that don't cater exclusively to the beat mongers (the opposite in fact), and Andi personally has composed quite a few tracks for the videos that very much fall within the realm of proper music, when he could just as easily have clicked his mouse a couple of times to arrpegiate some inane sequences in order to showcase some new addition to the library or software. Now that is just great and requires effort and time which he could have easily saved without hurting VSL's sales - maybe he did hurt them!... Similarly, VSL and thankfully EWQL as far as I know, have yet to record huge slabs of Hollywood earblockbuster claptrap for the deaf hopelessfuls (alla Gluemina, INaction Strings, etc.). I for one am very grateful for that.
As far as how to use the library to its potential (i.e. tutorials etc.) is concerned, they don't have to do anything, and they probably could not even if they wanted to. The best demos I have heard save for the original Blue Danube, have come from users who, understandably, won't publicize their secrets and will protect their livelihoods. Beat's and VSL's own tutorials address the beginner to intermediate level users, and then we are all on our own.
The other important thing to remember is that most of the other "libraries" address the """""""""Epic""""""""" cloneposers, and their knobs and buttons seem to be easier and get more immediate results, simply because those results are the only ones they are capable of. That's what they were created for. VSL's vast palette that allows for so many different kinds of musical use (as so many disparate demos from the top users have proven), has resulted in a "dashboard" that is much more sophisticated. To continue the metaphor, VSL is a Ferrari, and as such can be driven by an old lady, somebody like myself, or Schumacher, and of course the course results will be appropriate in every case. The difference with most other libraries/cars is that Schumacher will also be satisfied by VSL's handling.
Since VSL has yet to embrace my idea of its own notation+DAW all-in-one, my wish is that it will continue to explore more user friendly (i.e. musically intuitive) ways to work with the leading notation packages on the market. I compose with Sibelius and I will pay serious money for a "magic" VSL something that will read my sophisticated notation with all articulations and dynamics as automatically and integrally as Sibelius Sounds, ARIA, or NotePerformer do, during the compositional stages, and then it is up to me to export everything to a DAW for intricate nuances, automation, etc.
