Qtractor is a
hard disk recorderand digital audio workstationapplication for Linux. Qtractor is written in C++ and is based around the QT4 library by Trolltech. Its author is Rui Nuno Capela, who is also responsible for the very widely used [http://qjackctl.sourceforge.net/ Qjackctl] , [http://qsynth.sourceforge.net/ Qsynth] and [http://qsampler.sourceforge.net/ Qsampler] line of Linux audio software. Qtractor's intention is to provide digital audio workstationsoftware simple enough for the average home user, and yet powerful enough for the professional user.
Qtractor is currently under rapid development, and CVS versions are updated often with new features.
Released under the terms of the
GNU General Public License, Qtractor is free software.
Qtractor is a digital audio and MIDI multi-track composition and arranger software application. Besides its name, it should be noted, Qtractor is not a music “tracker” type of program. However, it has all the potential to do that job, if needed.
Qtractor is a non-destructive sequencer and arranger. It does not affect, alter or modify in any way, the audio and/or MIDI files that are displayed as Clip Objects. What is destructive are files resulting from capture and recording operations, and explicit changes made through specialized Clip editing (e.g., MIDI Editor).
Currently the Qtractor project is simply the hobby of one developer. Development was started April 2005, initially as a Qt3 application. Since October 2006, it is officially a Qt4 application.
Qtractor is natively hardwired and exclusive to the
JACK Audio Connection Kitinfrastructure, and the ALSA sequencer for MIDI, thus currently being a Linux-only application.
Supports all sample rates only restricted by hardware.
Supports multiple audio file formats, both compressed and uncompressed, including older formats such as 8SVX and .iff.
Clip editing and automatic or manual Time Stretching abilities.
Supports most major audio and MIDI file formats and most Linux plugin technologies.
Clips, may be easily edited by simply dragging the left or right edges for cropping, or even for timeshifting, by using the shift key modifier.
Qtractor may be used in a
audio masteringenvironment. Its integration with JACK makes it possible to use mastering tools such as JAMinto process the audio data.
Qtractor has both an audio and MIDI metronome with user selectable audio samples.
Easily move and copy plugins (with params) among tracks.
Keyboard commands (hotkeys) are entirely customizable.
Audition audio files within the Files dialog.
Built-in [http://qjackctl.sourceforge.net/ Qjackctl] Connections dialog.
Supports LADSPA, DSSI (this includes DSSI-VST wrapper) and Native Linux VST plugins (VST effects only presently).
Qtractor relies on plugins to enable many features from
audio effects processing to dynamic control. Qtractor supports the LADSPAplugin architecture, as well as [http://dssi.sourceforge.net/ DSSI] and native VST. Support for Steinberg's VST plugin standard with Wine is available using the [http://dssi.sourceforge.net/download.html#dssi-vst DSSI-VST] wrapper. Qtractor "remembers" all these connections, and re-establishes them when a the Session project is reloaded.
As Qtractor is a
free and open source softwareapplication; anyone can read and modify the source codeof the program.
