Topic: Actus Tragicus BWV 106 - Sonatina (Bach)
There is a wonderful video on Youtube with Paul Van Bladel playing a piano version of the Sonatina from Actus Tragicus.
It was instrumental in bringing me to Pianoteq. So, once there, I tried it myself at home ;-)
(More details about the transcription in the YouTube description.)
