Has there been an update of the barbershop template since 2018 that allows on just one treble and one bass clef each vocal part, tenor, Lead, baritone and bass that can be set up and exported individually as MP3s, with full separate control of the instrument sound to each part. The volume of each part should be individually controllable such that a full mix can also be produced with the volume of each part set to provide a predominant single part and other parts at a lower level. This is so that separate teach tracks can be produced. The existing Musescore Barbershop template that I have been works alright until you reach the output stages then I don't seem able to produce the export outputs that I need. I think there might be the same problem with the PDFs that can be output.
