MIDI files contain note data, not audio. The sound depends on the synthesizer. This player uses a General MIDI soundfont, which may differ from your DAW instruments.
This tool is for playback and visualization. To export audio, import the MIDI into a DAW and render it with your preferred instruments.
MIDI files are typically very small (under 1 MB). The player handles files up to several megabytes without issues.
