This is my original piece.
I used different violin models experimentally according to the range and each string of the violin.
I think that the realism of each violin model differs depending on the range.

Feedback is welcome!

The sound seems perfect to me (no expert with classic sounds at all)
But I always find the rather constant vibrato speed, and also the vibrato evolution rather unrealistic.
Since I play violin sounds and AM Cello on the Seaboard with "natural" finger wiggling vibrato, I like playing virtual strings a lot more - even though I still need a lot of practice until something in a quality remotely similar to your example might emerge.

Thank you for your feedback!
The violin vibrato is always a problem for me. I think that the representation of the natural vibrato randomness that a violinist plays probably will be a better result by real-time input such as Seaboard.
I can not play MIDI keyboards well, so MIDI CC is all handwritten, but it may be time to rethink the input device.
