Several new free soundfonts have been added. Attributions are included in the individual soundfont files and all soundfonts have also been added to the DIYino Prime SDCard image and SoundFont.h configuration.
This release also contains a fix for addressing more than 255 files on an SD card, which is needed when loading 8 or more soundfonts. Previously this would lead to the wrong sound being played in certain cases (as the result of an integer overflow).
Be sure to also update your DFPlayer library when updating from an earlier version.
