Improving MIDI playback in various open source projects

[peteroupc]

The following issues seek to improve support for MIDI software synthesis in various open-source projects. MIDI software synthesis, in this sense, means decoding standard MIDI files to digitized sound (e.g., PCM) in software, with the help of sound banks.

Libmodplug (FFmpeg):

• https://trac.ffmpeg.org/ticket/11017
• Enhancing libmodplug's playback support for MIDI files and other "instrument-free" music formats Konstanty/libmodplug#97

FluidSynth:

• Additional instrument source formats for software synthesis; looping support FluidSynth/fluidsynth#1275

SDL_mixer:

• Improving MIDI playback support libsdl-org/SDL_mixer#563

Gstreamer (and eventually Showtime):

• https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/2962
• https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/2956

Musetree:

• Improving sound quality using a wave table synth stevenwaterman/musetree#80

Wildmidi:

• emergency sound bank generator Mindwerks/wildmidi#121

Showtime:

• https://gitlab.gnome.org/GNOME/Incubator/showtime/-/issues/56

A public-domain music synthesis library and instrument banks would greatly help improve MIDI playback support across the open-source ecosystem: https://peteroupc.github.io/graphics.html#building-a-public-domain-music-synthesis-library-and-instrument-banks
