certain BBCSO instruments are not suitable for single notes, so I set by ear a different situation for each: mono note, multi-note, all notes
and I prefer that a different Scaler drives each BBC SO, because different instruments require different approach to me: one cannot drive a violin as it was a basson or timpani
As I said, it works perfectly with the Garritan, so I’ll go likely for the Garritan series
BBC SO Discover is too complex to drive, apart using my super-easy workflow I explained here and can be implemented in any DAW, I think
