Anonymus, Aus tiefer Noth

Score available here: partitura.org/i...
Manuscript Mus Ms 30439 owned by the Staatsbibliothek in Berlin is, despite the bad shape it is in, an interesting manuscript. It contains a segment with 16 chorale preludes of (mostly) unnamed composers. Two or three are definitely by Johann Pachelbel and three of them is by Johann Michale Bach. But for now the composers of the other ones are unknown to me.
This is the first piece of manuscript Mus ms 30439 I do not know the composer of. But whoever he was, he (or she) surely was someone who knew what he (or she) was doing. The piece starts like a French ouverture. After 14 bars it turns in the more familiar form of a chorale melody in long notes and a accompaniment that is build from elements of the chorale melody. The rythm of the first bars returns in the accompaniment in the last six bars. All in all a very well written beautiful piece. But who is the composer?
If anyone knows who the composer is, please let me know in the comments below.
The recording was done on the sample set of the Müller-organ in the Sint Bavokerk in Haarlem by Voxus Organs for Hauptwerk.
