This short work by Krebs is a canon between the soprano and the bass.
I am using an edition from a collection named "Oxford Service Music for Organ" - Manuals and Pedals Book 1. This series of 6 books (3 for manuals only and 3 for manuals with pedals) was compiled and edited by Anne Marsden Thomas and was published by OUP in 2011.
The suggested registration is for full flue pleno including 16 foot on the manual, with full pedal including reeds at 16, 8 and 4 on the pedal. Arlesheim has all of this except for the recommended 32-foot pedal flue. MIDI file attached.
