Open Source C++ Music Composition Software

The MIDI sequencer that features a rich understanding of music notation along with basic support for digital audio

WYSIWYG design, notes are entered on a "virtual notepaper". TrueType font(s) for printing & display allows for high quality scaling to all sizes. Easy & fast note entry, with many editing functions. MusicXML import/export, and MIDI (SMF) import/export. MuseData import, MIDI input for note entry, with integrated sequencer and software synthesizer to play the score. You can print or create pdf files. MuseScore provides a number of learning resources to help the new user get started. When you run MuseScore for the first time, the Startup Wizard appears to help you set up some basic features of the software. One of these features is called Tours, and, as the name suggests, gives you a guided tour of the program. MuseScore offers a full set of instructions videos, each covering a specific subject. In the Tutorials section on musescore.org you will also find tutorials on more specific topics (e.g. MuseScore Drumline).

MuseScore is the leading free & open source music notation software for Windows, Mac and Linux. It is easy to use and makes beautiful sheet music. MuseScore is often praised as a cost effective alternative for Sibelius and Finale. Support MuseScore at http://musescore.org/en/donate Like MuseScore on Facebook: http://facebook.com/musescore

Psycle is a Music tracker (like FastTracker 2 or Impulse Tracker) combined with plugin modularity. It supports its own plugin API, the VST2 plugin standard, and a tracker style sampler playback.

Rakarrack is a stereo digital effects processor for Linux with jack support. Standard line-up of nearly 40 effects modules include Equalizers, Reverbs, Echo, Flange, Chorus, Distortions, WahWah, Vocoder, and other filters and processing modules.

QMidiArp is a MIDI arpeggiator, phrase generator and controller LFO for ALSA and JACK. It can run multiple synchronized arpeggiators, LFOs and step sequencers. The modules are also available as LV2 plugins with Qt user interface. QMidiArp has been growing since june 2009 on top of Matthias Nagorni's original arp idea.

A free sound editor, DarkAudacity is the well known Audacity sound editor now with a darker more modern theme - and a few small tweaks. The audio engine underneath is the same audio engine. The same code powers it. Like Audacity it is completely free. It's not a cut down trial evaluation version. You can record and play sounds, edit sounds, apply audio effects and save what you create for ringtones, podcasts and more. DarkAudacity is Open Source, free for you to download and use on your PC. Audacity and DarkAudacity come from a community effort. Many people have contributed to the audio code. Because they are Open Source, anyone is allowed to read and modify the source code. DarkAudacity is a variation on the Audacity software, made possible because Audacity is Open Source.

MusE is a Qt based audio/midi sequencer with editing and recording capabilities for linux.

Takt is a text-based language for describing note and chord sequences as well as algorithmic compositon rules with C-like syntax. This software package contains a REPL (read-eval-play loop) interpreter for Takt, a MIDI-file-to-Takt translator, and an Emacs interface program which enables note entry from a MIDI keyboard.

Mutabor is a Program that allows performing and composing microtonal music using a normal MIDI keybord. But it's powerful description language is intended to allow permanent retunings and tuning logics in to describ, what's actually goes on.

Standalone, LV2 and VST instruments & effects generating weird sounds, noises and glitches, for experimental music. Heavily inspired by the Futurist musician Luigi Russolo, the aim of this project is to create new instruments for the new century.

NOTE: This is a legacy sourceforge project. Please download the software from https://openmpt.org/ instead. The official code repository can now be found at https://source.openmpt.org/browse/openmpt/ OpenMPT is a Windows-based audio application used to produce music. The application was initially a private project developed by Olivier Lapicque and is a popular 'tracker' used by many musicians. OpenMPT is available as both a 32-bit and 64-bit application. For more information and downloads, see https://openmpt.org/ libopenmpt, a cross-platform module playback library, is based on the OpenMPT project. Up-to-date libopenmpt downloads and documentation can be found at https://lib.openmpt.org/

Compose chiptunes with text files! And make mp3 and wav files of your songs to share with the world :) The audio synthesizer engine comes with 10 channels (9 music + 1 drum). The retro "beep" sounds reminiscent of old video game consoles and vintage PCs will take you back to the 8-bit era. You can shape your sound with waveforms - square, sawtooth etc. - and add LFO, delay and volume envelopes. Enjoy the 80's-ish synth drums, also!

PsalticTools includes: • a set of utilities (plugins) for typing of Byzantine notes in parallel double notation (Byzantine and Western), based on MuseScore free music editor; • the PsalticHelper program for searching for formulas of Byzantine music in music books. • the UniPsaltica2 font with the characters of the musical Byzantine notation in Unicode.

The SpatGRIS2 is an external multichannel sound spatializer for different configurations of speakers in 2D or 3D. SpatGRIS2 may include up to 128 inputs and outputs. DOME, CUBE, BINAURAL and STEREO modes are available. SpatGRIS2 provides the new CUBE algorithm that allows the use of any speaker configuration. Warning: SpatGRIS2 is not compatible with Catalina and up. SpatGRIS3 is now available. SpatGRIS2 and ControlGRIS have been developed by the Groupe de Recherche en Immersion Spatiale (GRIS) directed by Robert Normandeau and based at the Faculty of Music at Université de Montréal. Software, manuals and patches are available in Files. UPDATE (August 1st). SpatGRIS3, 100% compatible with Catalina and Big Sur is now available: https://sourceforge.net/projects/spatgris3/ You can subscribe to our mailing list to receive updates about ControlGRIS/SpatGRIS3 at our web site: http://gris.musique.umontreal.ca

The ZirkOSC3 is a plug-in that allows the user to control the spatialisation through the Zirkonium MKII from any Mac AU or VST compatible audio sequencer. It has been developed at the Faculté de musique of the Université de Montréal by the Groupe de recherche en immersion spatiale (GRIS). To install it, just drag-and-drop it into the component or VST folder of your Mac. The development of ZirkOSC33 has ended on December 2015. It has been replaced by SpatGRIS which is a fusion of OctoGRIS and ZirkOSC: https://sourceforge.net/projects/spatgris/ We have also developed a new 3D software, the ServerGRIS, that replaces the Zirkonium (Version 1.04, March 26, 2018): https://sourceforge.net/projects/servergris/
