Kauffmann's chorale prelude to "Erschienen ist der herrliche Tag" is a fugato play between the first two phrases of the chorale melody. Kauffmann notates it on two staves with no indication of a pedal registration. Yet I thought it fitting to play the two lowest occurences of the chorale melody wqith the pedals. Just to give it an extra punch.
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).
