I'm a long time MuseScore2 user. I'm transcribing Bulgarian field recordings so it entirely fits my needs for single melody lines, hijaz modes, and unusual rhythms like 13/8. Recently I've started collaborating with a composer who needs Finale source files so he and I can exchange tunes. I'm sure the oldest crufty Finale version I can find on eBay will do everything I need (I used Finale back in the 90's and it did then). But MakeMusic has a reputation nearly as bad as Adobe on software pedigrees. What is the current wisdom about used Finale software and registration?
