Hello there and again,

This time getting ready for the NYE. Prepare to party, the countdown has 
begun... but first, let there be just one cheesier announcement ;o)

   Qtractor 0.7.3 (a tackier gluon) is released!

Everyone is strongly invited to upgrade. No excuses.

   Qtractor [1] is an audio/MIDI multi-track sequencer application 
written in C++ with the Qt framework [2]. Target platform is Linux, 
where the Jack Audio Connection Kit (JACK [3]) for audio and the 
Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main 
infrastructures to evolve as a fairly-featured Linux desktop audio 
workstation GUI, specially dedicated to the personal home-studio.

Change-log (since last cheesy release):
- Slight increase on the number of decimal digits for the plugin 
parameters while on the generic plugin properties dialog. Also applied 
to automation curve node value editing.
- Unlimited slack is now in effect on editing over and beyond the 
current session or clip contents length, on both the main tracks and 
MIDI clip editor (piano-roll) views.
- Ctrl+click and dragging the left or right edges of a clip will now 
make it spill over and replicate as many clip clones as it fits in the 
left or right horizontal extent.
- Added View/Note Type and Value Type command menus to the MIDI clip 
editor (aka. piano-roll) which opens the possibility for discrete 
shortcuts to switching views eg. Note Velocity and Controller views 
(after a kind request by yubatake, thanks).
- Fixed the conversion and/or override of MIDI clip offsets when moving 
and copy/pasting across tempo/time-signature changes.
- Fixed MIDI file track/channel duration estimator, which was giving 
quite wrong and way too short reads.
- Fixed a drag-and-drop bug over the main tracks view, when new tracks 
were being inserted at the top and not to the bottom as is normally 
indicated by the floating visual placeholder.
- Fixed LV2UI_Resize handle from extension_data(LV2_UI__resize), now 
passing LV2UI_Handle in first argument to ui_resize(), as found correct 
and needed for resizable/scaleable LV2 UI's, most specially to ssj71's 
so called Infamous Plugins, thanks.
