TiMidity++, originally and still frequently informally called TiMidity, is a software synthesizer that can play MIDI files without a hardware synthesizer. [1] 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.


TiMidity++ can read a number of file types and devices, primarily the ordinary .mid files, but also .kar (MIDI with Karaoke lyrics), [2] Recomposer files, and module files. [3] It is one of the few programs that can read MIDI .mid files using the MIDI Tuning Standard. TiMidity++ also has support for SoundFonts, rendering the synthesized MIDI sounds into their recorded SoundFont equivalents and directing the output to the soundcard. [4] Files can be fetched from standard input, files, archive files, or from the network (over HTTP, FTP or NNTP).

The program has various interfaces, including but not limited to bare text, ncurses, X11 (Motif, Xaw, GTK+ and Tk) and even an Emacs interface that shows played notes in real time.

TiMidity++ has some support for microtonal music. [5]


The original version of TiMidity was written in 1995 by Tuukka Toivonen. After he stopped updating the program, Masanao Izumo and other contributors started to work on the program, renaming it to TiMidity++. [6]

MIDI Means of connecting electronic musical instruments

MIDI is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper Universal Synthesizer Interface published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City.

Csound is a domain-specific computer programming language for audio programming. It is called Csound because it is written in C, as opposed to some of its predecessors.

LADSPA Application programming interface for audio filters

LADSPA is an acronym for Linux Audio Developer's Simple Plugin API. It is an application programming interface (API) standard for handling audio filters and audio signal processing effects, licensed under LGPL-2.1-or-later. It was originally designed for Linux through consensus on the Linux Audio Developers Mailing List, but works on a variety of other platforms. It is used in many free audio software projects and there is a wide range of LADSPA plug-ins available.

A software synthesizer or softsynth is a computer program that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional synthesizer. Softsynths may be readily interfaced with other music software such as music sequencers typically in the context of a digital audio workstation. Softsynths are usually less expensive and can be more portable than dedicated hardware.

Virtual Studio Technology Software plug-in interface used in computer-based audio production

Virtual Studio Technology (VST) is an audio plug-in software interface that integrates software synthesizers and effects units into digital audio workstations. VST and similar technologies use digital signal processing to simulate traditional recording studio hardware in software. Thousands of plugins exist, both commercial and freeware, and many audio applications support VST under license from its creator, Steinberg.

Digital audio workstation Computer system used for editing and creating music and audio

A digital audio workstation (DAW) is an electronic device or application software used for recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece.

FluidSynth, formerly named iiwusynth, is a free open source software synthesizer which converts MIDI note data into an audio signal using SoundFont technology without need for a SoundFont-compatible soundcard. FluidSynth can act as a virtual MIDI device, able to receive MIDI data from any program and transform it into audio on-the-fly. It can also read in SMF (.mid) files directly. On the output side, it can send audio data directly to an audio device for playback, or to a Raw or Wave file. It can also convert a SMF file directly to an audio file in faster-than-real-time. The combination of these features gives FluidSynth the following major use cases:

Mus2 Scorewriter

Mus2 is a music application for the notation of microtonal works and, specifically, Turkish maqam music. Unlike most other scorewriters, Mus2 allows the user to work in almost any tuning system with customizable accidentals and play back the score with accurate intonation. The application has also received praise for its clean interface and usability.
