How to use NotePerformer alongside another VST?

you can’t delete the old VST instances from within a project unless it’s the very last one. There has just been another thread confirming this here

You’d need to first delete 66-70 and then you could one by one delete 2-65 and then reinstate the others. A much better general solution seems to me to use Vienna Ensemble Pro for the BBC stuff – performance and loading times will both be improved.

If including Noteperformer, load its Playback Template first and then add the VE Pro entries underneath. I don’t think that NP works properly without using the pb template. I should say that this is how I would expect the optimal setup to be — I don’t generally mix Noteperfomer with other libraries so haven’t actually tried out the sort of sketching idea you suggest. There may well be other ways.
