I am using GPO/ARIA, and running it through Sibelius. All works well, except and I can't get up/down bows on the KS instruments. I understand that it can't be made to happen via text like pizz/arco (which work just fine), but inserting the keyswitch pitches don't have any effect. I can get the sounds if I open up the ARIA interface, and use the drop-down menu on the lower left, but that is not optimal, obviously. Any thoughts?
As always, thanks in advance.
