Thanks again!
Regarding the Brandenburg demo, I am really surprised it is so close to a Baroque ensemble, and very well played with the right hand of course. I don't like the strings, but as they don't dominate here and the harpsichord and other voices play a great role, the overall sound is close to original.
The only thing I noticed is, from 1:20 onwards, there are counter melodies (such as an oboe counter movement simultaneous to the trumpet voice) which the player does not play live and which cannot be part of the style either (as they don't "jump" with harmony changes), so they have to have been pre-recorded/programmed.
