Noldar, thanks for your reply. I hope you are not going to think me obtuse, but in Sibelius there is no way I am aware to adjust modwheel - in fact, in terms of Sibelius I'm not sure the term has any meaning at all. You said, 'setting the mod wheel to +8191 (the max adjustment up IIRC)' - how would I do that inside Sibelius? It isn't a sequencer like Logic or Cubase. The 'score' is not piano-roll style but only conventional music notation. I have no idea what that would mean in Sibelius. And what is IIRC?
Steve, thanks for that suggestion. I thought that might not work because of soundsets, but I see now if the articulations replace the usual ones they should get triggered anyway. I'll try it.
But even so I 'd like to understand what Noldar is suggesting.
