Qtractor is a MIDI/Audio multi-track sequencer application written in C++ around the Qt4 toolkit using Qt Designer.

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, especially dedicated to the personal home-studio.

Qtractor 0.7.7 is out since April 2016. But also the 0.5.11-version from 2013 (LinuxMint 17.n xfce, repository) has the very flexible bus system, no track limits, no plugin limits and all advantages of JACK audio-deamon (adjusting latency, USB-audio, sample depth, etc). CALF PluginPack, fluid-soundfonts and some DSSI-Instruments & Synths from Linux Mint's repository made my DAW complete! For notation or Tabs, I export midi tracks to musescore or Tux-Guitar. For surgically wave editing (repairing waves), I use audacity. Workaround to deblock LinuxMint's native PULSE AUDIO (multimedia audio daemon) after using JACK (professional audio deamon): Open taskmanager, killing jackd... (sometimes also jackdbus). After 2 seconds, Mint's pulseaudio works fine again. Hardware: USB compliant audio interfaces. Update March 2019: There's a switch in a newer Jack/Qjackctl: "Shut down JACK" after shutting down Application. No need for my workaround anymore!

Great Sequencer! Already very useable, and even more promising for the future.
