This distribution includes the original editable audio bank and the complete
GPL-2 license. The sixty MP3 clips in assets/piano/ are renderings of the
source bank using FluidSynth, with effects disabled, at MIDI velocities 55
and 105, sampled at 32 kHz and MP3-encoded with FFmpeg. Keep this attribution
and the included source and license when redistributing these audio assets.

This is an audio instrument bank, not a bundled typeface. Interface typography
uses fonts already installed on the visitor's operating system; no font files
are distributed by the website.
