Fogpad is a reverb effect in which the reflections can be frozen, filtered, pitch shifted and ultimately disintegrated. This is an unofficial port of the Regrader plugin created by Igorski. It is available as an LV2 plugin and a standalone JACK application.

Samplebrain chops samples up into a 'brain' of interconnected small sections called blocks which are connected into a network by similarity. It processes a target sample, chopping it up into blocks in the same way, and tries to match each block with one in its brain to play in realtime.

Audacious is an audio player descended from XMMS. Drag and drop folders and individual song files, search for artists and albums in your entire music library, or create and edit your own custom playlists. Listen to CD’s or stream music from the Internet. Tweak the sound with the graphical equalizer or experiment with LADSPA effects. Enjoy the modern GTK-themed interface or change things up with Winamp Classic skins. Use the plugins included with Audacious to fetch lyrics for your music, to set an alarm in the morning, and more.

XUiDesigner parses an LV2 plugin's ttl file and generates the needed controller widgets. The created GUI can be saved as UI-Bundle, which then could be built and installed. For later editing of the UI, a JSON file is added, which you could load per drag 'n drop into XUiDesigner.

mididings is a MIDI router/processor based on Python, supporting ALSA and JACK MIDI. Features include:

• MIDI routing and filtering; filter events depending on their event type, channel, note number, velocity, etc., and freely route them between an arbitrary number of input and output ports.

• Modifying and converting MIDI events; transpose notes, apply velocity curves, change controller values and ranges, or convert events to any other MIDI event type. mididings also includes more complex functions like a diatonic harmonizer, floating split points, latched notes, and more.

• Seamless switching between patches; set up different "scenes", each with its own MIDI routing and processing, and switch between them at any time, even while playing. Switching scenes does not affect notes already held, and does not result in dropouts or stuck notes!

• MIDI event monitoring, running external commands; print MIDI event data to the console to help debugging your patches and configuring your MIDI controllers. In addition to its MIDI output, mididings can also execute shell commands and send OSC or DBUS messages.

This set of LV2 plugins is a port of the internal modules found in Alsa Modular Synth. These plugins are used to create modular synthesizers and contain: VCO, VCF, VCA, LFO, slew limiter, envelopes, sample and hold, etc.

x42-plugins is a collection of over 80 cross-platform LV2 audio and MIDI plugins that can also run as standalone JACK applications.

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.

The MusicBrainz::DiscID module is a Perl interface to the MusicBrainz libdiscid library, allowing you to manipulate digital audio compact disc (CDDA) identifiers.

This module searches the MusicBrainz database through their web service at musicbrainz.org.

The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. Then it provides a variety of tools for manipulating and accessing your music.

Clementine is a multiplatform music player. It is inspired by Amarok 1.4, focusing on a fast and easy-to-use interface for searching and playing your music.

Abjad helps composers build up complex pieces of music notation in iterative and incremental ways. Use Abjad to create a symbolic representation of all the notes, rests, chords, tuplets, beams and slurs in any score. Because Abjad extends the Python programming language, you can use Abjad to make systematic changes to music as you work. Because Abjad wraps the LilyPond music notation package, you can use Abjad to control the typographic detail of symbols on the page.

ArtyFX is an LV2 plugin bundle of artistic real-time audio effects. It contains a bitcrusher, delay, distortion, equalizer, compressor, and reverb.

mod-host is an LV2 plugin host for JACK, controllable via socket or command line.

The Non Sequencer is a powerful, lightweight, real-time, pattern-based MIDI sequencer. It utilizes the JACK Audio Connection Kit for MIDI I/O and the NTK GUI toolkit for its user interface. Everything in Non Sequencer happens on-line, in real-time. Music can be composed live, while the transport is rolling.

Clyrics is an extensible command-line tool to fetch the lyrics of songs. It can be used in daemon mode along with the Music-on-Console (MOC) and cmus console music players.

abjad-ext-nauert provides classes for dealing with composer and music theorist Paul Nauert's quantization grids or Q-Grids, for short.

GNU LilyPond is a music typesetter, which produces high-quality sheet music. Music is input in a text file containing control sequences which are interpreted by LilyPond to produce the final document. It is extendable with Guile.

Aj-snapshot is a small program that can be used to make snapshots of the connections made between JACK and/or ALSA clients. Because JACK can provide both audio and MIDI support to programs, aj-snapshot can store both types of connections for JACK. ALSA, on the other hand, only provides routing facilities for MIDI clients. Aj-snapshot is meant to be used from the command line.

B.Shapr is a beat/envelope shaper LV2 plugin.

This package contains data files for use with Le Biniou.

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player.

Flacon extracts individual tracks from one big audio file containing an entire CD of music and saves them as separate audio files. To do this, it uses information from the appropriate CUE file. Also, Flacon makes it possible to conveniently revise or specify tags both for all tracks at once or for each tag separately.
