Hi Jan,

Please accept my sincere apologies for the long delay in the reply to your message. It looks as if the liga feature in Bravura Text has been broken for some time: I'm very sorry about that. (If you're interested, we use a script to manipulate the main Bravura font file in order to produce the Bravura Text font, which involves duplicating glyphs, moving them vertically, and then building a very large liga feature table with over 15000 entries; unfortunately the liga table has not been correctly set up for some time, and I had failed to notice the problem.)

I have just committed a fixed version of Bravura Text to GitHub here:

https://github.com/steinbergmedia/bravura/raw/master/redist/otf/BravuraText.otf

You should find that this version operates exactly as the documentation suggests it should. Do let me know if you have any further problems.

Daniel

I'd like to confirm that I am encountering the exact same behaviour as
described by Trevis and azzadeen. I tried on Mac in TextEdit, Open Office,
and in Xcode as .textValue for a UILabel. I only get noteheads on middle B
line.

The only further ressource I could find on the web is this discussion on
stackoverflow:

https://stackoverflow.com/questions/34559025/how-to-use-the-music-font-bravura-text

In the "manual" posted on GitHub Daniel says:
Daniel s. wrote

My understanding of this would be, that there are indeed 17 discrete
variations of each symbol (noteheads e.g.), each on an actual different
position, just as in a regular font a hyphen and an underscore are complete
different characters.

But as I simply cannot get this to work, and considering the replies in the
stackoverflow discussion, my impression is, that either these modifiers
(combining staff position glyphs) just provide some information of how much
vertical offset should be added to the regular glyph, OR, that all my
available applications fail to identify the combining staff position glyphs
as ligatures. Regular ligatures like fi or fl work fine in all cases.

So, as the Bravura Text imho is targeted towards users that seek a
convenient way to use a simple form of notation in a text based application,
without having to deal with shifting around individual glyphs by code, I
really would appreciate if someone could give me a simple explanation, what
else I have to implement in either my code, or my textviewing app to use
these feature.

Maybe it is just one property that has to be set to true to make the
ligatures visible to the program.

Or can someone at least confirm that there is an application in which this
feature works as intended, or if it is even maybe a mac specific issue?
