I am doing some research (I started from a refill for Reason, it consists of very well-made solo violin and cello sounds, the cost is truly
ridiculous, but the site from which it would have been possible to download them by purchasing them is not online, so I started looking around a bit, and since my motivation
comes mainly when there is something to build, with these individual samples you can create mappings and "create" complete sounds) and I
found these free sites:
http://www.philharmonia.co.uk/thesoundexchange/make_music/samples/library/
You can download the .zip files containing the available articulations; they aren't all there and some recordings contain two/three sounds in a row,
so they need to be cut and processed, but that is what I was looking for (at least I was), I am more interested in these real samplings than the sounds already prepared
by companies.
Of course, the hard part is putting all the dynamics together, but I know how to do it anyway.
Not only that, almost none of the samplings have a reasonable duration for certain types of passages, but by working on them they could be
not bad.
This is a Vst (I still have to try it):

There is also this site, years ago I had already downloaded these sounds, but I hadn't mapped them; you can also find the files already zipped but the download
won't start for me:
http://theremin.music.uiowa.edu/MISpiano.html
Here is an example of zipped samples at the bottom of the page, they are available in both 16 and 24 bit,
(the one for the piano and all the other instruments won't start, but it isn't on this site, rather on another link):

Warning, some samplings are damaged anyway, and only 2 articulations are available.
