Summarized Changelog:
- Fixed editing and display of 'Pgm Change' events on the MIDI clip editor (aka. piano-roll).
- Introducing tempo/beat-detection support on the Clip.
- Updated for the newer Qt5 development tools (>= 5.13).
- Imply asking for a brand new filename (ie. Save As...) whenever the session file original sample-rate differs from the current audio device engine (ie. JACK)..
- Fix MIDI through for LV2 plug-ins that have no MIDI output event/atom ports.
- Plugin-lists and respective plugins state may now be exported and/or imported as XML files.
- When in Drum Mode, Key and Scale are meaningless and thus functionally disabled from the MIDI clip editor.
- MIDI clip editor's View > Ghost Track menu option is now finally a reality: show any existing MIDI track and its respective clips in the background as dimmed, semi-transparent aka. ghost events.
- Make sure partially selected clips are reset to whole when Shift/Ctrl keyboard modifiers are in effect, to prevent extraneous clip splits or cutaways afterwards.
