I agree that a strong vibrato here and there can be effective, but I've so far only heard this with real orchestras, when I hear these libraries with molto vibratos, and sounds great for a few notes but after that all the vibratos are so predictable to become annoying that I find this to be a bigger problem in my opinion since expressive vibratos are different and have their own character on every single note. I think in virtual music it's very difficult to solve one problem without creating another, so the best thing is to look at the qualities of a library and adapt, if you are looking to have it all, hire a real orchestra.
And although I'm still learning to get the best from synchron strings, and making mistakes, I'm convinced that it won't stop me from creating some pretty amazing sounding works in 2018, and of course combined with WW and brass and synchron percussion, will sound pretty damn full!
Just in general:
If this thread is so popular, it's probably because people want more and better from what they are currently using and expect synchron to solve all their problems and some expected to make mockups of JW on a 1st try. No virtual library will do that. Sorry. If you're dwelling so much on the imperfections you lose focus on the positive and there is a lot here. Some people on this thread have said about 50 times the same comment like a broken record while only 3 times about the positive.
