This is the Sinfonia to Cantata 35 'Geist und Seelle wird verwirret' by J S Bach. It is played on a home constructed Moog Modular 3C I built from schematics about 15 years ago and am still completing. Some of the sounds have been sampled direct from the 3C when the tuning became an issue and the piece was not recorded onto tape, as was the original S.O.B's, but directly to digital multi track.
