One of the playlists on the PASK YouTube channel contains personal stories from pianists, including excerpts from their first try-out sessions. https://www.youtube.com/playlist?list=PLHBn-VaaOCGcAanKWSo7pCA0GFfQa7N1b
See this video by Canadian pianist Linda Gould telling the story of her DS5.5® keyboard. It also clearly illustrates her problems with the conventional keyboard and why it did not allow her the opportunity to pursue a concert career.
And see the moving video of Tiffany Goff trying Steinbuhler keyboards for the very first time.
