Local MIDI files load directly from your computer for inspection and playback.
This web player uses a compact generated soundbank and Web Audio waveform fallbacks, so
imported MIDI files may need their track mapping adjusted to sound better here. MIDI
files are instructions for instruments to play or trigger events, not full audio
recordings, so an external song will not sound exactly like its original playback unless
it used the same instruments, note ranges, and synth settings.
The generated soundbank keeps this site small and self-contained, but it is an
approximation rather than a full General MIDI soundfont.
GM is the base 128-program standard. GS and XG usually keep those base meanings and
extend them. Game / chip heuristic keeps the same numbers, but leans the automatic
remapping toward console-style MIDI conversions.
