First of all, thanks for your very kind comments!
I think I must disappoint you guys: The reverb is simply the built in "RoomWorks" from Cubase 4.
About articulations: The bigger libraries (Solo Strings, etc.) do have a bigger sortiment of articulations and much more varieties of different lenghts of detachés, etc.
I used the following articulations in SE (Std) for the demo: staccato, detache, sforzato, pizzicato and tremolo (on Violin Solo, Viola Solo, Violoncello Solo). (still some more articulations left) As I have played the instruments "live" into my sequencer the switches of articulations are not really perfect at all, but if you take your time and edit it with patience you might get much more realistic results (one note staccato, the next one detache, a sforzato, etc.) those little details pay really off (you can see a great tutorial by Beat Kaufmann). Of course the bigger collections offer you much more varieties to "construct" really every little nuances that you wish.
About the Section Strings: The "Orchestral Strings" in SE are really beautiful as well. Same articulations as the solo strings above.
As I have only the Standard Edition I do not have access to the "Chamber Strings" and "Appassionata Strings", but that doesn't matter to me but I'm thinking of downloading "Strings PLUS (Std)" that gives me additional articulations (also for contemporary composition) as "con legno" techniques, "sul ponticello", "harmonics", "perf. repetitions", and many more... I think that's a good expansion for the beginning.
If you'd like to hear the orchestral strings you can check my second soundclip I just did it yesterday night. Nothing special though, I tried the first time to load and set up a basical VI orchestra in Cubase and as a test I orchestrated quickly a simple piano piece in Satie style that I wrote once on university.
I did the same way as with the solo strings: I played every single instrument "live" into my sequencer and didn't edit anything (or only little) afterwards. It's not perfect at all but might show how easy and comfortable it is to play "live" with the Vienna Instruments and what kind of results you get from the very first note on.
