This is an organ arrangement of a movement from Sonata TWV 41-F2. I cannot tell you who arranged it as I found it on just two loose pages when tidying up the organ loft one day, but I think it does a good job of evoking the swirling sound of treble recorder and continuo.
The sample set has two sampled positions, close to the console and about 10' distant. This recording uses the distant samples with a little added reverb.
