[Breaking Changes]
A new default soundfont has been written that replaces bank 0. If you have added a custom soundfont that uses bank 0 to Resources/Audio/MidiCustom/, you may get your bank’s sounds overwritten by this default, depending on the order the files are loaded. Any server using its own choice of soundfont should delete the Resources/Audio/MidiCustom/GeneralUser-GS-Bank0.sf2 file. If you don’t know what any of the above means, you’re probably OK. You can also delete this file if you prefer to use system default soundfonts.
