It's not that unusual for me to have problems with the wrong instrument playing if I'm trying to set up a new template in Sibelius, usually simple user error. But now I'm stuck. My horns play as trumpets as well as the trumpets. In Sibelius playback devices, everything looks fine and the horn sound test is a horn. In the Edit Instruments the default sound is unchanged at Horn. It is correct in Vienna Ensemble also. But go to the dreaded Sibelius mixer and under channel 9 and 10 you get the following description "brass.horns.french.horn -Trumpet" as can be seen from the screenshot below. I have no idea where this comes from?
Perhaps this query should go to Sibelius but I notice that I can get quick and accurate answers here. Anyway I'd also like to ask a quick bit of advice. Currently using Vienna Ensemble v2. Is it advisable to update to Vienna Instruments v.5 and, most importantly, will existing Sibelius scores be able to deal with this without major reprogramming (as far as I can remember the update from VE1 to 2 was troublefree but this could be a more drastic step)
Many thanks,
David
