What's Qtractor ?

Qtractor is an Audio/MIDI multi-track sequencer application written in C++ with the Qt framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio, and the Advanced Linux Sound Architecture (ALSA) for MIDI, are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later.

The software requirements for build and runtime are listed as follows:


Optional (opted-in at build time):


Qtractor's already in some kind of beta stage of development and hence fully functional. Though, the bleeding-edge development source tree is readily available from the sourceforge's public Git repository.

Latest release

2021-07-10 - An Early-Summer'21 Release.

Previous and older pre-releases, including the change log, are also available here.

You can browse all files available for download, including binary packages, at Qtractor Files on SourceForge.net.


Unpack the tarball and in the extracted source directory:

cmake [-DCMAKE_INSTALL_PREFIX=prefix] -B build -S .

make -C build

and optionally as root:

[sudo] make -C build install

Note that the default installation path prefix is /usr/local .

See also the README.cmake file in the source distribution.


Qtractor holds its settings and configuration state per user, in a file located as $HOME/.config/rncbc.org/Qtractor.conf. Normally, there's no need to edit this file, as it is recreated and rewritten everytime qtractor is run.


Probably plenty still, Qtractor maybe considered on beta stage already.


Qtractor is open source free software. For bug reports, feature requests, discussion forums, mailling lists, or any other matter related to the development of this piece of software, please use the Sourceforge project page.

The dated Qtractor quick start guide and user manual for version 0.5.x has been authored by Seth Kenlon & Klaatu.

The older user manual for version 0.3.0 and before, have been co-authored by James Laco Hines and Stephen Doonan.

Qtractor logo/icon is an original work of Andy Fitzsimon, borrowed from the public domain openclipart.org gallery.
