Qtractor

Qtractor is an Audio/MIDI multi-track sequencer application. The initial target platform is Linux, using the infrastructure of the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI. It is meant to be a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home studio.
