Here's my take - SY violas only, a tiny bit of delay on top of the factory preset (and nothing else). Vibratos are not even close, but I couldn't make them any better. Well, I'm only learning to use this library, and this was a good exercise:

One thing I tried myself was having them play loud and with maximum vibrato, and then using CC11 to make it sounds softer. But I couldn't get the attacks to sound right. 😞
