Hello one third and last time time, for a little while :)
Didn't you know?
Qtractor 0.9.22 (spring'21) has been released!
- Fixed one terribly old and overlooked mistake that was preventing MIDI
tracks volume and panning automation to take effect on audio export.
- All packaging builds switching to CMake. 
Qtractor  is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework . Target platform is 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.
