Samples created by Christian Henson for his incredible site: pianobook - a growing library of free piano samples. https://www.pianobook.co.uk/
All I did was map the samples in Kontakt and apply one of my old GUI designs on top to give some handy sound controls. Head on over to https://www.pianobook.co.uk/ to get other free piano samples for both EXS and Kontakt formats, as well as the raw samples. If you want to contribute to pianobook you can contact them through their website.
