Hi,
I couldn't find any topic with this same problem. I hope I can get some help here.
I'm trying to use "a4" and "a3" on horns and trumpets in Sibelius with the Synchronized Special Edition.
Sibelius changes to the correct midi channel but doesn't use the correct keyswitch. With a4 on the horn part, it's stuck on legato as the default sound. With a3 on the trumpet, it's stuck on major 2nd trill as the default.
Changing to other articulations works, so the problem is just that the default for some reason is those I just mentioned.
I have the Sibelius Sound Set and have imported the House Style. The manual sound set is set up correctly. I have of course double checked that the midi channels are correct in Vienna Ensemble.
Btw, I'm using Sibelius 2020.3 and the latest version of Vienna Ensemble and the Synchron player.
