Musical Notation Software
With our partner Arpegemusic, we have developed a software to write Jianpu musical-notation, http://www.arpegemusic.com/alternative-music-notation.htm, details http://www.arpegemusic.com/manual36/EN284.htm.
You can download a testversion.
The program was originally developed for conventional music notation. Thereafter supplements for alternative notations that are based on numbers have been added. If a notation is present, you can create and edit the other notations on mouse click.

No, you cant load a demo version of ‘Alternation Notation’ from the Pizzcato/arpega website. What it will do is download ‘Pizzicato Light’ but not with a test version of Jianpu, HMN in it.
I have emailed their ‘Support’ twice now-but not response.
So if you want to offer me a demo version, and it works/or even exists at all, I am happy to buy it from you direct.
Will you let me know.
Many Thanks.

I will get in contact with Arpege and ask Dominique to fix the Problem.
I Do not sell the program myself. It is only available from Arpege.
Thanks for Your interest.
