Interesting video from Christian Henson, who does a lot of great sounding orchestral sampling library’s for Spitfire Audio, about a very cool project called ‘Pianobook’.
Where they offer several free library’s created by people from all over the world, for example a very nice Choir library that was made in a collective effort.
They are all free: Pianobook
Library’s can depend on either one of these: Kontakt, EXS24, SFZ
