Re: [fluid-dev] Proposal for a new feature: lazy-loading of SoundFonts

Hi again, just out of curiosity, I analysed a large library of MIDI files with regard to the number of program change events that they contain. I downloaded the geocities collection from https://archive.org/details/archiveteam-geocities-midi-collection-2009, containing around 51000 MIDI files

Re: [fluid-dev] Proposal for a new feature: lazy-loading of SoundFonts

Hi all, So I think I'm probably the best placed to speak since I'm using fluidsynth both as a MIDI player and as a real-time synthesizer on Android. Obviously I didn't wait for this feature to be implemented to create my applications, so I can say that I don't them... like at all. for the

Re: [fluid-dev] Proposal for a new feature: lazy-loading of SoundFonts

Hi Tom, yes, it's a little hackish... but not the part you mention, I think. Overriding the "authority" of the synth over when and which samples to load is perfectly valid, in my opinion. Yes, those functions would also need to be exposed to the user via the shell and API, but that would actually

Re: [fluid-dev] Proposal for a new feature: lazy-loading of SoundFonts

Sorry, I think it's a hack. Dynamic sample loading is implemented in a way to allow the synth to control when to load or unload presets and samples. Introducing this fluid_defpreset_t::loaded_manually flag overrides the synth's authority. Instead the midi player gets in charge of that. If

Re: [fluid-dev] Proposal for a new feature: lazy-loading of SoundFonts

I keep thinking about this preloading feature and I'm not yet fully convinced of it. I see quite high obstacles for it being beneficial i.e.: - We need a user who plays MIDI files via command line and listens to them in real-time. - The user must actively enable on demand sample loading - The

Hi all, the dynamic-sample-loading branch has been merged into master. I will follow up with a few more pull-requests that add more bells & whistles to the feature, like the preloading function, but also some changes that reduce the memory consumption of the structural information of Soundfonts.

Re: [fluid-dev] Proposal for a new feature: lazy-loading of SoundFonts

Let me just clarify: As of 1.1.7 audio rendering does not lock any mutex. Previously, you had the option to set "synth.parallel-render" to false, causing any thread attempting to enter fluid_synth_write_*() to acquire the lock. However, this caused bug #192, because the current synthesization

Hi all, thank you very much for your feedback! Good to know that there is interest for this feature outside of my particular use-case. I've decided to go the route Tom suggested: concentrating on the samples first and leaving the "structural" information loading unchanged for now. That will

So briefly, your main motivation for this feature is memory usage. Absolutely comprehensible on an embedded system. You therefore want to parse only "high-level preset information" of a SF file. I'm missing information about SF2 Instruments here. Counterproposal: Instead of lazy-loading
