I recently purchased Spitfire Symphony Brass, which uses the Kontakt player. To select from a variety of articulations and techniques, often it is necessary to load multiple patches for the same instrument. I’m using Spitfire’s [UACC KS](What is UACC KS and how do I use it? – Support Centre approach in my expression map, which combines CC with a single key switch. In the video you can see the solo trumpet loaded twice in a single instance of Kontakt. The top patch contains several standard articulations and the bottom patch contains only flutter-tongue, which I select in measure 5 for one note before returning to legato. As the test piece plays, hopefully you can see how Dorico controls the selections.
In measure 6 I used the Natural playing technique to “stop” the flutter-tongue. I’ve read many older posts here that recommend using Natural to end a playing technique. Not doing so results in additive behavior on top of flutter-tongue. But my question: is there a newer/better way to use mutual exclusion groups in the expression map to end flutter-tongue instead of inserting Natural into the score and hiding it? I haven’t figured out if that is possible with the way I’m using Kontakt and UACC KS.
