This is a list of free SFZ/SF2 libraries that I will keep updated as I discover new ones.
If you know of any library under a free license not mentioned here please shoot me a message. Note that all of these explicitly allow re-distribution, even of modified versions. Non-free soundfonts or unlicensed ones are not included.
TODO: find some from here https://bb.linuxsampler.org/viewforum.php?f=8
