Interesting. Your site says 

NorFonts are third party music symbols and text fonts which can be used with Sibelius, Finale and Overture 5 (Mac and Windows users)... (and so on)...

I see the packages for Finale and Sibelius. Which would one use for Overture 5? Not sure that I have the need but I do have current licenses for Finale and Overture.

Why would you not make them SMuFL compliant these days since most notation apps are migrating (slowly) to that standard and some are already there?

Nor,
Here are two links to maybe get you further down the road with SMuFL font conversion/creation. The first link is mostly SMuFL information. The second link discusses a possible automated conversion process using the free font editor "FontForge" and a windows version of a JW Lua script concept.

I'm not sure if his "official" release version is available yet or still in beta - but the web pages talk very confidently about it's software capabilities, one of which is a SMuFL font conversion discussion.

Good Luck!

Thanks Doug!

The Elbsound font conversion program can convert to any music font standard. But as I only use Finale myself and haven't have had any requests for SMuFL conversion yet, I haven't tried it out in detail. I have only done conversions to the Finale format (Elbsound Music Fonts Package, https://elbsound.studio/elbsound-music-font-package-for-finale.php) and to the Sibelius format so far.

The Elbsound font database includes about 900 music symbol descriptions (but there are more SMuFL symbols). So currently it could convert only these. All other symbols would not be touched in the conversion process.

Hi,

Now my BopMusic music font is SMuFL compliant featuring more than 1300 music symbols. I released the fonts for Overture 5, whereas for Dorico, it will be soon available.
