Qtractor is an Audio/MIDI multi-track sequencer application
written in C++ around the Qt toolkit.
The initial target platform will be 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.
There is no official package available for openSUSE Leap 15.4
