foo_midi is a foobar2000 component that adds playback of MIDI files to foobar2000.
It is based on MIDI Player by kode54.

Features

• Decodes General MIDI files (.MID, .MIDI, .RMI, .KAR) and several MIDI based formats. (.MIDS, .MDS, .HMI, .HMP, .MUS, .XMI, .XFM, .LDS, .RCP, .R36, .G18, .G36, .XMF/.MXMF, .MMF).
• Supports several synthesizers, several of which do not require any additional files to play back music. The bundled synthesizers which do not require additional files may sound rather basic, though.
• Supports FluidSynth SoundFont (.sf2) based synthesizer, including support for the newer compressed format. (.sf3). SoundFonts may be loaded in a simple, or even complex setup, using either basic .sflist text files encoded in UTF-8 format, but for now, it only supports a bare list of files.
• Supports 32 and 64-bit VST instruments.
• Supports dark mode.

Requirements

• Tested with Microsoft Windows 10 or later.
• foobar2000 v2.0 or later (32 or 64-bit version).
