Here is a different version of the chorale by Reger. This one is very expressive, although it stays on the same manual throughout. The score calls for 8' + 4' so I used the Recit Diapason and flute octave. The pedal is 16' + 8'.
One day I'll finally get around to trying to sort out the Behringer foot pedal so the swell is a bit more subtle!
