Hello,
I don’t know if that subject has already been talked about.
but I would love to be able to sell my music on a digital platform that accepts Dorico’s files.
Even better, be able to sell it from Dorico’s website like apple and the app Store 
I use Score exchange for years now, it’s ok but not great.
They accept Sibelius files but not the latest version so I end up upload PDF from Dorico now.
They take over 50% commission and the look and feel is not really the top edge 
So if you know a good place to sell digital music sheet,
please let us know.
Best regards
