In a project I'm working on, which had no issues, I have added two Horns, and now playback doesn't work properly. The Horns are playing on the Trumpet channels in VE, nothing is happening on the Horn channels, and the two trumpets are playing on one channel. In the Sibelius mixer the Horns weren't allotted Horn sounds but Trumpet sounds, so I set all the channels in the mixer to auto, and eventually the Horns were allotted Horn sounds, yet on playback, they are still playing on the Trumpet channels in VE, with of course Trumpet sounds. Why is it so temperamental when adding extra instruments? What can I do to change it?
