Since some months, I'm working on Musescore code to make it support Shamisen notation;
At first it was very inefficient because there was many glyphs problems (layout mostly)
It's still in development and I'll submit it to the developers to let them see it it can be implemented or not but for the test version that I currently have, it's very near the goal and it already can produce scores
It allow to have the Bunka-fu 文化譜 notation with it's different tunings
And also the Nagauta notations: 小十郎譜; 弥之介譜
I'll post again here if there is progression.
You can hear a sample of the song here
(Modified for test purpose)
That is absolutely amazing! Otsukaresamadesu :p
Really though if that's approved that'll be a huge help to sharing scores since the old online tab reader Karl made has been down for some time. Thank you for your hard work!
