Chorale prelude "Christus, der ist mein Leben"

This short chorale prelude by Walther can be found in "Seasonal Chorale Preludes for Manuals Only - Book 1" edited by C. H. Trevor, published by OUP in 1962. I understand the book is still available.

The first church organ I played (from 1969 until 1976) had a Great organ of 4 stops - Open Diapason 8, Hohl Flute 8, Viola 8 and Harmonic Flute 4. The Open Diapason was one of the finest I've heard, but it didn't even have a Principal 4 to go with it. Anything which passed for "upperwork" had to be coupled from the 6-stop Swell, which went up to a Fifteenth 2.

Ever since then I've always looked to see how a Principal 4 stacks up in any organ (or sample set) I have played.

For this I've coupled all three manual Principal 4 stops on the St Mary-le-Bow multi-channel sample set - along with balancing unison registers (flutes on Gt and Ch, Diapason 8 on Sw).
