Qtractor is a free and open-source Audio/MIDI multi-track sequencer application that targets at the GNU/Linux platform, as it uses JACK and ALSA as main infrastructures.
Qtractor is developed on pure Qt4 C++ application framework that eliminates the need for any Qt3 or KDE dependencies. It features non-destructive, non-linear editing and supports many audio formats including MP3, OGG, WAV, FLAC and AIFF. MIDI files are also supported of course.
Qtractor offers built in useful editing tools like mixers and monitor controls, metronomes, loopers, configurators and a vast number of plug-ins. One of the usability highlights though is the configurable keyboard shortcuts.
