Qtractor is for me the ideal DAW since 2013. It has a very flexible bus system, no track limits, no plugin limits and all advantages of the JACK or the Pipewire audio-deamon. It handles many different plugin formats. For score notation or tabs, I export midi tracks and open them in Musescore, Tux-Guitar or Rosegarden. Simple wave-editing can be done, but for more complex things, I use Tenacity (from the audacity developers). Hardware: USB compliant audio interfaces. Since I use it (2013), the software improved along the demands of their users. It's a great DAW for people with a low budget and the will to learn an application!
It's the second time I installed it and try to make it output something...While everything else is working very good, keyboard, lmms, vlc playback, etc. This program never ever start without giving error messages. I installed Jackd, qjackctrl, no error message from both...give up.
Great Sequencer! Already very useable, and even more promising for the future.
