Hi all.
I'm playing around with a headless RPi with fluidsynth and I'm
thinking of incorporating a small display with button controls to
select things like the preset, the octave, transpose, etc. I'd like
to be able to extract the preset names and numbers from the target sf2
file so I could use them in the display program, but I'm having
difficulty finding a suitable utility.
Any suggestions? Python would be nice...
Ben

Hey Ben,

there's the sf2utils package: https://pypi.org/project/sf2utils/

I've used this for a while for exactly the same use-case: reading the
preset names and displaying them in a list. It works quite well, but is a
little slow opening Soundfonds with a large number of presets / instruments
/ zones.

I've since created my own module that is much faster, as it only reads the
preset names and doesn't load all the information about generators,
modulators, instruments etc. You can find the code here:
https://github.com/midigurdy/mg-core/blob/7af42f4bedc7fd071fab139b21e7444d24e5b361/mgurdy/src/mg/sf2.py#L160

Cheers,

Marcus

And I wrote something in C [1] - if I only had known about sf2utils...

Thanks Marcus (and Andreas).

I'll give both of those a try. Is there a way of just getting the preset
no. and name using sf2utils?

The following works, but it's difficult to separate the "name" from
other info

sf2parse filename.sf2 | grep Preset

I get:

Preset[000:056] Trumpet 2 bag(s) from #0
Preset[000:057] Trombone 2 bag(s) from #2
Preset[000:064] Soprano Sax 2 bag(s) from #4
Preset[000:065] Alto Sax 2 bag(s) from #6
Preset[000:066] Tenor Sax 6 bag(s) from #8
Preset[000:068] Oboe 2 bag(s) from #14
Preset[000:071] Clarinet 6 bag(s) from #16
Preset[000:070] Bassoon 3 bag(s) from #22
Preset[000:073] Flute 5 bag(s) from #25
Preset[000:074] Recorder 3 bag(s) from #30
Preset[001:056] Trumpet 2 9 bag(s) from #33
Preset[001:057] Trombone 2 4 bag(s) from #42
Preset[001:060] Solo French Horn 2 bag(s) from #46
Preset EOP

Of course, it can be done, but is there an easier way?

Hi,

here is some documentation about sf2utils:
https://pypi.org/project/sf2utils/
Especially the "Library use" and "High level library API" sections are
interesting for you use-case.

Cheers,

Marcus
