I am learning the passacaglia and fugue, and wondered what thought others had on registration. I want to keep it fairly simple, with perhaps manual changes (Gt. Principals 8 & 4, with Pos. Principals 8 & 4) for the first few pages, and then using a lighter flute reg. with a principal chorus/plenum from b. 128. It all has to be hand registration, as I don't "approve" of pistons etc. for Bach!
