Hi Ross!
For the trumpet you don't have to set anything in the manual sound sets tab, because you don't use a sound set. If the trumpet plays on one of the Sound Essential channels, go to the Sibelius mixer and set Vienna Ensemble (and if necessary channel 1) as output device.
Creating your own C Trumpet Sibelius matrix in Vienna Ensemble:
1) Go to Patch Assign.
2) Drag the border of the empty matrix, so that you have place for 12 patches horizontally.
3) Choose the patches you will need in your score and drag them one after the other on the free spaces. (probably staccato, one or two of the sustains, one or two of the Performance Intervalls, ...)
4) Click Control Edit and set H-Span to Keyswitches starting with C1.
5) You can now change articulations from Sibelius with MIDI commands as described earlier in this thread.
6) By saving your Playback Configuration you automatically also save your settings in Vienna Ensemble.
