Qtractor 0.9.18 (fall'20) is out!
- When under NSM, all top-level windows, main, mixer and connections,
will always start hidden.
- Plugin editors (GUIs) that are currently open on a track are now
brought up as top-level windows immediately when a track is made current
or highlighted (and Track / Auto Monitor is in effect).
- MIDI clip editor mouse hovering effect extended to whole current note
line on main view (piano-roll eye-candy++); also, the white keys on MIDI
clip editor's virtual piano keyboard, are now fully highlighted.
- Plugin search paths (View > Options... > Plugins > Paths) now lists
all the default and actual existing paths, instead of a blank list.
- Undimmed octave divider lines on the piano-roll.
- Fixed potential crash on changing audio output buses channel count.
- Note names display (inside note rectangles) are now an option on the
MIDI clip editor (aka. piano-roll; menu View > Note Names).
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.
