ardour/gtk2_ardour/canvas-midi-event.h
Hans Baier fbfe9a7983 * implemented editing velocities (http://tracker.ardour.org/view.php?id=2148)
* added MIDI panic button (http://tracker.ardour.org/view.php?id=2118)
* bugfix: moving notes above midi 127 or below 0 does not wrap around anymore
* bugfix: deadlock on editing notes after playback (http://tracker.ardour.org/view.php?id=2140) due to unbalanced lock acquire/release
* bugfix: First note off lost in playback (http://tracker.ardour.org/view.php?id=2132)
* bugfix: Last note off lost in saving MIDI files (http://tracker.ardour.org/view.php?id=2132)
* bandaid fix for http://tracker.ardour.org/view.php?id=1985 (Cannot reopen session because jack ports are not unregistered on session close)
* bandaid fix: replaced conf.CheckPKGExists ('\"slv2 >= 0.6.0\"') by conf.CheckPKGExists ('slv2') in SConstruct, because the former would fail, 
  even if SLV 0.6.0 was installed
* added/enabled debugging output for debugging MIDI model (might be removed later)
