A beautiful chorale prelude (two chorale settings included) from Joachim Frisius of the hymn 'Ist Gott für mich, so trete'. The original tune comes from an English ballad from Elizabethan England, around 1590.
I intended to use this recording for my presentation of Nitra sample set in December 2021, because it shows the two manual reeds. But that presentation ended up as a Christmas video, so I left this recording out of it.
Thanks to Willem van Twillert for allowing me to show some snippets of the score.
