I also own the original Tina Gio acoustic Cello. Basically. This library would give me a ‘less emotional’ solo cello
I would not buy this for the solo cello.
Although you are of course correct that it can accurately be described as 'less emotional' than the Tina Guo. And I guess it can add a bit of definition to a line using it as a first chair.
But there's a reason there's virtual no demo of it available.
