The GMP library performs arbitrary-precision arithmetic on signed integers, rational numbers and floating point numbers. The precision is only limited by the available memory. The library is highly optimized, with a design focus on execution speed. It is aimed at use in, for example, cryptography and computational algebra.

GNU MPC is a C library for performing arithmetic on complex numbers. It supports arbitrarily high precision and correctly rounds the results.

This package supports both a double-double datatype (approx. 32 decimal digits) and a quad-double datatype (approx. 64 decimal digits). The computational library is written in C++. Both C++ and Fortran-90 high-level language interfaces are provided to permit one to convert an existing C++ or Fortran-90 program to use the library with only minor changes to the source code. In most cases only a few type statements and (for Fortran-90 programs) read/write statements need to be changed. PSLQ and numerical quadrature programs are included.

Power Tab Editor 2.0 is the successor to the famous original Power Tab Editor. It is compatible with Power Tab Editor 1.7 and Guitar Pro.

Geonkick is a synthesizer that can synthesize elements of percussion such as kicks, snares, hit-hats, shakers, claps and sticks. It can also play and mix samples.

Samplv1 is an old-school polyphonic sampler synthesizer with stereo effects.

This package provides the LV2 plugin "GxPushPull", a simulation of a push pull transistor fuzz effect with added high octave.

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.

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.

The jalv.select package provides a graphical user interface allowing users to select LV2 plugins and run them with jalv.

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.

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.

Zam plugins is a collection of audio processing plugins in the LADSPA, LV2 and VST2 formats, as well as standalone JACK versions. The collection includes ZaMaximX2, ZamAutoSat, ZamComp, ZamCompX2, ZamEQ2, ZamGEQ31, ZamHeadX2, ZamPhono, ZamGate, ZamGateX2, ZamTube, ZamDelay, ZamDynamicEQ, ZaMultiComp, ZaMultiCompX2 and ZamSynth.

This package provides an LV2 plugin that allows for pattern-controlled MIDI amp & time stretching to produce shuffle / swing effects.

Key features include:

1. MIDI velocity amplification and timing manipulation plugin

2. Swing and shuffle rhythms

3. Pre-generator dynamics

4. Tempo rubato

5. Pattern (sliders) or shape-controlled

6. MIDI filters

7. Smart quantization

abjad-ext-rmakers includes a collection of classes for creating and and manipulating rhythms such as accelerandi, taleas, and more.

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.

Stargate is a digital audio workstation with built-in instrument and effect plugins and wave editor, providing innovative features, especially for EDM production.

a2jmidid is a daemon that implements automatic bridging of ALSA midi devices to JACK midi devices.

LINGOT is a musical instrument tuner. It's accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments.

It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, determined automatically as the closest note to the estimated frequency.

This package provides a multi-channel MIDI step sequencer LV2 plugin with a selectable pattern matrix size.

This package provides the LV2 plugin "GxVintageFuzzMaster", a simulation of the vintage Fuzz Master pedal.

The 6581 SID chip is the sound chip used in the Commodore 64 computer. reMID is a MIDI implementation of the 6581 SID chip using the reSID library to provide a virtual SID-based synthesizer, controllable in real-time via MIDI. It includes support for scripted instruments that allow complex sonic control of the chip.

The VL1-Emulator is an emulator of Casio VL-Tone VL1, based on source code by PolyValens, offered as an LV2 plugin and a standalone JACK application.
