Re: [fluid-dev] Extracting preset names and numbers

[Marcus Weseloh]

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,

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?
