This piece appears not only in Neumeister's manuscript, but is present in Mus. Ms. 30439 as well. I published the version from that last source two years ago (http://partitura.org/index.php/johann-michael-bach-von-gott-will-ich-nicht-lassen/) and it is (of course) present in the Edition based on that manuscript (http://partitura.org/index.php/choral-preludes-from-mus-ms-30439/). The version in Neumeister's manuscript differs is several little details from the version in Mus Ms 30439. And it's a nice reason to play this piece again. In both versions it is a very well written three part choral prelude. The recording was done with the Hauptwerk software and the sample set of the Silbermann organ of the Stadtkirche Zöblitz by Prospectum (http://www.prospectum.com/index.php?language=english&id1=2&id2=8).
