I’m exporting an mp3 of a piece with 16 ‘voices’. Voice 16 is a saxophone track and the mp3 does not include this voice. If I change the voice for another, the track is still silent in the mp3 . That voice is not set to mute and playback is normal – just the mp3 which doesn’t include it, whatever it is set to.
I can see posts about totally silent mp3s but that’s not the case here. Am I missing something obvious?
