Thanks. The link which you provided is exactly what I was looking for. Nothing else is required from a lower level.


In our software mainly General MIDI soundfont are used. The objective is not to tweak nor edit anything from the soundfont samples. As General MIDI soundfont become better and better and include more banks than just bank 0, the objective of knowing the instrument names is to display these instruments to the users that the user can select any instrument soundfont sample from any bank and is able to allocate that instrument sound to any MIDI track of a MIDI file.


E.g. a soundfont file may contain a Standard „Guitar“ soundfont sample in bank=0, Num=27  but also a „Fender guitar“ or a „Gibson guitar“ sample in higher banks.  The objective is to display these instrument names to the user. Thx.

I understand that FluidSynth primary usage is not a SoundFont editor, but being able to live edit the SoundFonts would be awesome.

ATM, you can only get the names of the soundfont presets, see preset iteration here:


Everything below that level, i.e. which samples belong to which instruments and which instruments to which presets, is currently internal to fluidsynth.

What could be implemented pretty straight forward is iterating over all the samples that a soundfont has. This might also include lonesome samples, that are not linked to any instrument. Also, you would not know which samples belong to which preset and the soundfont instrument layer would be invisible as well.

Implementing an iteration over all instruments of a preset as well as all samples of an instrument would need some discussion, but it would make sure that you only see instruments and samples that are actually used. In this case it would be good to know what's the benefit you're intending by displaying sample names to the user and what else you're planning to do when you have the sample. Thinking of e.g. changing the sample's wave form and manually spawning voices from it.
