[fluid-dev] [PATCH] sampledata caching

[Kjetil Matheussen]

Hi,

I'm embedding FluidSynth as an instrument in the Radium music editor 
(http://users.notam02.no/~kjetism/radium).

It works fine (thanks for the great work!), but the memory usage was 
sometimes shockingly high because fluidsynth reloads
entire soundfonts for every new synth, even if the soundfont was 
already used in a different synth.

Maybe I have misunderstood something, but instead of spending several 
more hours trying to figure out if I had misunderstood
something, I modified fluidsynth to cache already loaded sampledata 
from soundfonts.

Here's the patch: 
http://users.notam02.no/~kjetism/fluid_defsfont_patch.diff

Please let me know if there's anything that's needed to do in order for 
you to use it.

I also have a question: Can delete_fluid_defsfont and 
fluid_defsfont_load_sampledata be called from different threads at the 
same time?
In so, we also need a lock protecting the global list of cached 
sampledata.
