When I am arranging HS, notes drop out constantly, like a synth running out of voices.
I like the East West samples in general, and admire that company a lot, but have to say that the VSL Appassionata are the best overall string sound available, and have become my normal strings in all arrangements.
The reason is, that although you can throw out a lot of gigabytes and "features" and so on, the basic string sound is what really matters. In my experience, there is nothing that can approach the Appassionata violins, violas and cellos in the basic, instant, beautiful rich string tonality. And it is fairly low in CPU demand. That is because the playing and recording was tweaked to be a deep and rich string sound that composers usually want. You can record a million samples of something that doesn't have that, then brag about how big it is, but it still will just cause a lot of problems.
Also, what you bring up with the interface is what I've noticed many times - the VSL software using Vienna Ensemble is so logical and useable, that I no longer want to use Kontakt or other proprietary sample players and in fact am becoming very choosy about them. Because none of them are as good as Vienna Ensemble. It is so easy and musically logical to load, select and play, that I no longer want to deal with the "All samples in your lap and you figure out how to use them" approach of other players.
I should emphasize that probably no one will ever regret getting the Appassionata strings. I am doing a new recording that uses a lot of strings, and though I have done a huge amount of Appassionata recordings, I was still freshly amazed by the instantantaneous beauty of the sound using them. It is astounding how authentic the sound is using the simple combo of: legato 4-velocity, sustain, detache and staccato. Four articulations! And they cover almost everything you could ever compose.
One other thing - they are tweaked in general so that the most needed, useable sounds are all right there, instead of being buried within a lot of unnecessary patches. But if you want something less usual, you can always supplement with more App articulations, such as tremolo or sforzando/dynamics, or the other strings that VSL offers, and they fit perfectly into the workflow. Including the divisi effects possible with Orchestral or Chamber/Solo, as well as adding Solo on top of Appassionata for more "texture" effects of espressivo in doubling violin, viola or cello lines.
