one of the most beautiful chorale preludes of JSB, many times uploaded already on CB. I tried a more 'stringy' registration on my Weissenau sampleset:
Pos Principal 8'
HW Principal 8', Quintadena 8' (cf)
Ped Subbass 16, Violonbass 8'
I find this registration quite suitable, but I'm curious what you think about it.
