Hi Peter,
This was Christian's response regarding his use of VSL Brass..
"...Regarding how I get this Brass sound, I have to say it is a mixture between Brass I and Brass II. I never use the Horns from Brass I, because they are different in Vienna to the rest of the world. Not only construction wise but also in timbre. I always use the Triple Horn and Horn Ensemble from Brass II...but do use the Trombones from Brass I. I would recommend to get Brass II and in addition to the Single Instruments Tenor Trombone Full and Trombone Ensemble Standard.
What I like from Dimension Brass is again the Horns and the Trombones. But they are not so different in tone compared to Brass I/II (it's more geared to writing separate lines for all 4 different players). I guess it's because of the players, room recording chain...well this still is a VSL product..."
Hope this helps!
