soundfont

Hi,

Is it possible to select a synth (soundfont/sf2/sf3) for playback?

Hello,
I've never used soundfonts with abc2svg before so I'm not really familiar with how it works.
Could you provide an .abc example file that defines the soundfont and that you would expect to work?

I include all the abc2svg files in /lib, and only scc1t2 folder is present, so I suppose I would have to get them from another soure.

I published v0.4.9 that allows you to import soundfonts as js files. You can force VS code to install it by right clicking on the extension in the extension search and install specific version if it doesn't auto-update.

If you add
%%soundfont http://moinejf.free.fr/js/sf2/AWE_ROM_gm.js for example at the start of your file, it should pick it up.
See here for more information about how soundfonts are handled in abc2svg: http://moinejf.free.fr/abcm2ps-doc/soundfont.html

As far as I can tell, they only support sf2 format, and you need to convert it to a .js file for it to be loadable from any URL.
For it to load sf2 files, they would need to be bundled with the extension because of domain restrictions, and I don't think I want to add more size to it by adding soundfonts by default.

I'll ask Jean-François Moine if sf3 is supported or planned to support in abc2svg.

Hello, and thank you for your reply.

Actually, I was talking about the default soundfont used by the extension to play any song when no %%soundfont is specified.

• What is the default soundfont used?
• Is it possible to configure it?

[laurent-yin]

I use the default from abc2svg, Scc1t2.
From the link above:

By default, abc2svg uses a sound font extracted from the SF2 font Scc1t2.

There are no other soundfont files included in the extension so far. Which one were you looking to use?
Also, I haven't added any mechanism to change user settings in the extension, that would allow this kind of change on a per-user basis.

However, if your requirement is just to avoid having to write %%soundfont to all your files, there is a mechanism that I implemented to allow to externalize abc directives hierarchically. You put them in .abcconfig files in the containing folder or any parent accessible by VS code, and it will merge and prepend the directives to all your files.
See an example of a ABC repository with .abcconfig files: https://github.com/laurent-yin/choro-abc/tree/main
