Hello again, one third and last time...

But happy to announce yet another point release of, drum roll please...

Qtractor 0.9.23 (early-summer'21) is out!

Changes for this hot season are just but a few, nothing heartbreaking:

  • Dropped the 'Activate' option on the plug-in Selection dialog, now being as always on by default.
  • Have some tolerance for JACK buffer-size changes, only prompting to a complete session reload, if increasing in double the initial period size.
  • Introducing plug-in blacklisting, on user discretion (in View/Options.../Plugins/Blacklist) and on inventory scan (crashed plug-ins are now automatically blacklisted).
  • Added special support for LV2 UI GTK2 plugins based on Gtkmm 2.4 framework.
  • All builds default to Qt6 (Qt >= 6.1) where available.
  • CMake is now the official build system.

  • Add support for LV2 UI Windows platform (by AnClark, also while on synthv1).
  • Sustenuto pedal controller (MIDI CC#66) is now implemented.

  • Have some tolerance for buffer-size changes.
  • All builds default to Qt6 (Qt >= 6.1) where available.
  • CMake is now the official build system.

As usual, all delivered in dual form:
