Kauffmann's second chorale prelude to " Allein zu dir, Herr Jesu Christ" is even shorter than the fisrt one. Just 8 bars, whch are played twice. The chorale melody is in the tenor voice, so it makes a nice listening exercition: can you spot the chorale melody without looking in the score and by listening alone?
The recording was done with the Hauptwerk software and the sampleset, made by Voxus, of the Müller organ in the Sint Bavokerk, Haarlem (http://www.voxusorgans.com/en/product/haarlem).
