With the VSL Special Edition, separate instruments are used for some muted brass rather than articulations. The mute instruments match the articulations of the normal instrument. I found for the rare occasions when I’ve used this in Dorico so far that the easiest solution seems to be create a new instrument called “muted trumpet” for the trumpet players. The switch by moving the section to the mute staff in galley view works fine – or so I thought. In playback, however, although it switches to the correct instrument, it ignores articulation switches.
Fair enough, there are a number of possible reasons. But what I find puzzling is that it works perfectly when you bring up the part view or when you click on a note to audition it but in full score, it doesn’t. Without reference to a particular project, how can it be possible that Dorico reads an EM correctly in part view but not for full score? I should make it clear that the non-muted trumpet (with NoteLength and secondary dynamic controller) works fine throughout as do all other instruments.
