Thank you Arbee for your kind words. At the time, I was trying out Sibellius (contrary to the popular belief that one needs to use a sequencer in order to obtain the upmost realism) and created a complete set of Sibelius Sound Sets for a Modern Symphonic Orchestra. I was using MIR that sat inside of Vienna Ensemble -- the first version that came out that wasn't a MIR stand-alone. Everything on the arrangement was from the Vienna Library. For the Strings, I blended a mixer of the Orchestra Strings and Appassionata Strings libraries. I remember pretty much making a determination on what library I was pulling each articulation from while building the instrument presets.
I used Herb's Teldex MIR preset for a starting point, then modified it to fit the voicing of my custom orchestra.
To be very honest, I have all the competitor libraries as well but thinking back, rendering this piece using Sibelius was probably the most enjoyable, straight forward, and fun to work with. It's pretty darn hard to beat what Vienna has accomplished with the quality of samples and the amount of articulation that one has to choose from. Add to it, the MIR environment.... one spends more time writing and less time dealing with the mixing/technical stuff....
Very Happy you enjoyed the piece.
