[ardour-dev] latest CVS commit

[Paul Davis]

   * automation track "controls context menu" now includes
      "clear" and auto-state submenus, so that full control
      even using a small track height is possible.

   * require inserts/plugins to either be mono-input or match
      the active streams at that point in the route. this
      means you cannot insert a 2in plugin on a mono track
      without a 1in/2out splitter preceding it.

      we will change this in a future (post-2.0) version of
      ardour so that the splitter is added automatically
      in a hidden way.

   * fix naming of sends/inserts to avoid duplications.
 
   * libardour:  0.852.2
     ardour/gtk: 0.551.0
