I got this for the solo cello. The tone of the samples is quite good and realistic, but there are some issues that make it difficult to work with. First off, the samples only last so long. After it re-bows, it ends often with a crescendo and a hard lift. So you have to make sure you don't use not longer than the max. The hard lift is also usually what I don't want.
Secondly, there is room noise of some kind just after the hard release in many of the samples. So you would want to add a gate on filter that out. Thirdly, some of the notes are not in tune. In particular, D below middle C is quite off, and I had to add a auto-tune module to tame this. Fourth, it seems to be sampled all at the same level (on layer). So decreased velocity just gives a softer wound with the same hard attack. Lastly, some of parameters only work within a very narrow range, for example release. Move it just a touch and it gates off instantly with a click.
So while the actual tone is quite realistic and the price is free, there are some issues that make getting good results from this take a bit of work.
