I've already made the switch.
So much more organic! Not quite as convinced with the double bass, but I think if I find a good ratio for the body, I'll be fine (I have body and room switched off until I have everything else set the way I like, and definitely with have both at WAY lower settings than the defaults regardless).
As it's a lot to absorb at once, I haven't yet found where the articulation set availability is talked about. This frustrated me during a MUCH shorter audition over the holidays as well, as I see all these articulations that I want and need but are greyed out (19 are shown as available). So I'm not sure if that's for future expansion, or if some of the other orchestral products enable those and they're generic across the range (for instance, the terminology is fairly neutral, and detache is not listed, so this may explain the greyed out articulations as not part of the sample set for the Solo Strings).
To clarify, I'm talking about the full-page view of articulations. If I click the overview button, it shows me the key assignments, which is not what I am talking about. I thought this would be like Chris Hein Horns Pro (the jazz and big band package), where I can select unloaded articulations on a given keyswitch, but each keyswitch only lists the 19 that are already in use.
Just as in December, I am preferring working with auto vibrato curves vs. the synthesized vibrato that comes from modulation. That may change when I start using the Yamaha WX5 again though. I do notice though, that the longer articulation presets default to auto vibrato and the shorter ones to LFO vibrato.
My overall approach is the same as for VSL, which is to have a parallel keyswitch track, copy/paste the main track, shorten everything to 5 ticks, uniform note velocity of 64 (so I don't get confused and think it's a music track), pull ahead by about 12 ticks (I have learned over the years that simultaneous note and CC or keyswitch can cause non-deterministic behaviour or even glitches in the note starting with the previous setting), then play with the articulations and only cull the redundant keyswitches once confident of all choices.
I learned that approach from Beat Kaufmann's VSL tutorials, a few years back, and it changed my life. Previously, I didn't really have a strategy. And though this isn't a super-short process, it is WAY shorter than any of the other approaches I have tried over the years, and also is more flexible and leads to greater success and satisfaction with the results, at my end.
