LibSMF is a C library for handling SMF ("*.mid") files. It transparently handles conversions between time and pulses, tempo map handling and more. Full API documentation and examples are included.

Glyr comes both in a command-line interface tool (glyrc) and as a C library (libglyr).

The sort of metadata glyr is searching (and downloading) is usually the data you see in your musicplayer. And indeed, originally it was written to serve as internally library for a musicplayer, but has been extended to work as a standalone program which is able to download cover art, lyrics, photos, biographies, reviews and more.

Surge is a subtractive hybrid digital synthesizer. Each patch contains two scenes which are separate instances of the entire synthesis engine (except effects) that can be used for layering or split patches.

PaulXStretch is an application/plugin is based on the PaulStretch algorithm (Paul’s Extreme Time Stretch, originally developed by Nasca Octavian Paul), and specifically the PaulXStretch version from Xenakios.

GSequencer allows you to play, capture and create music. There is a piano roll, automation and wave form editor. It has machines for playing drum samples, Soundfont2 sound containers and synthesizers. They usually can be connected to a MIDI input source (instrument).

This package provides a library to access iPod contents. It enables iPod support in music players such as Clementine.

Ninjas 2 is a rewrite of the Ninjas sample slicer audio plugin. Its goal is to be an easy to use sample slicer with quick slicing of samples and auto-mapping slices to MIDI note numbers.

Pure Data (aka Pd) is a visual programming language. Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically, without writing lines of code. Pd is used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. Pd is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.

Midicsv reads a standard MIDI file and decodes it into a comma-separated value file (CSV), which preserves all the information in the MIDI file. The ASCII CSV file may be loaded into a spreadsheet or database application, or processed by a program to transform the MIDI data (for example, to key transpose a composition or extract a track from a multi-track sequence). A CSV file in the format created by midicsv may be converted back into a standard MIDI file with the csvmidi program.

klick is an advanced command-line based metronome for JACK. It allows you to define complex tempo maps for entire songs or performances.

This package provides the LV2 plugin "GxSaturator", a saturation effect.

This plugin for beets automatically obtains tag data from https://bandcamp.com/. It's also capable of getting song lyrics and album art using the beets FetchArt plugin.

Wolf Shaper is a waveshaper plugin with a graph editor. It is provided as an LV2 plugin and as a standalone Jack application.

This is the C implementation of the ORCΛ language and terminal livecoding environment. It's designed to be power efficient. It can handle large files, even if your terminal is small.

Orca is not a synthesizer, but a flexible livecoding environment capable of sending MIDI, OSC, and UDP to your audio/visual interfaces like Ableton, Renoise, VCV Rack, or SuperCollider.

AVLdrums is a drum sample player LV2 plugin dedicated to Glen MacArthur's AVLdrums. This plugin provides a convenient way to sequence and mix MIDI drums and comes as two separate drumkits: Black Pearl and Red Zeppelin.

Synthesis ToolKit in C++ (STK) is a set of audio signal processing and algorithmic synthesis classes written in C++.

This package also provides its demo project, examples, ElectricGuitar, RagaMatic and Effects.

Quod Libet provides several ways to browse and view your local music library, along with flexible search capabilities. It includes a tag editor, which can also be invoked as a standalone program, and further supports streaming audio and feeds (such as podcasts).

Musicbrainzngs implements Python bindings of the MusicBrainz web service. This library can be used to retrieve music metadata from the MusicBrainz database.

This project is a fork of the Android Open Source Project platform_external_sonivox. It is a Wave Table synthesizer, using embedded samples. It also supports external DLS soundfont files. It is also a real time GM synthesizer.
