Hi Andi
Thanks for your quick reply.
I have the sound set installed with Vienna Ensemble. In Vienna Ensemble, I load the muted trumpet sounds and can play them without any trouble. The muted trumpet sounds are exactly where you say (PRESET/Sibelius/Special Edition 5.2/SE Vol. 2/21 Brass/13S Trumpet C mute)
However, this does not transfer to Sibelius. That is to say, I have the muted trumpet sound loaded in Vienna Ensemble, but no muted trumpet sound plays back in Sibelius.
This problem is especially confusing becuase I have the muted trumpet sound loaded in its own channel in a manual sound set in Sibelius. When I test the muted trumpet sound in Sibelius, it plays a major scale with the muted sound. However, no muted trumpet sound plays when I play the score in Sibelius.
I have another question: what is the difference between VSL SE PRESET and Sibelius PRESET? All of the VSL SE PRESET sounds work for me. However, none of the SIBELIUS PRESET sounds playback through Sibelius. Yet, the sounds will play back in Vienna Ensemble...
I have just looked at the Optimizing Sibelius Playback document (p.20). I have already done what it says there (have two separate MIDI channels for the open and muted sounds of the same instrument). As far as I can tell, I am doing everything right.
There seems to be a more basic problem of none of the Sibelius PRESETS sounds working with Sibelius from Vienna Ensebmle. Why is that? How can I fix it? Have I not installed something correctly? Does Vienna Ensemble have problems working with Sibelius 8 (Sibelius 8 is pretty new)...
