TiMidity++

TiMidity++, originally and still frequently informally called TiMidity, is a software synthesizer that can play MIDI files without a hardware synthesizer. It can either render to the sound card in real time, or it can save the result to a file, such as a PCM .wav file.

TiMidity++ primarily runs under Linux and Unix-like operating systems, but it also runs under Microsoft Windows and AmigaOS. Distributed under the GPL-2.0-or-later, TiMidity++ is free software.
