With Python, you don't even need OSC, it can be much simpler,
just use RT events (and possibly channels). No need to involve
networking of any sort (unless you are using remote machines).

Chuckk,

I was (finally) able to get Rationale running last night and I would guess
that the playback problem is almost certainly the mouse movement callbacks.
(Unfortunately, the program crashes when I try to play a CSD though, so I
haven't observed the problem you described yet).

Many other GUI programs that use Csound have issues when the mouse is
clicked or held as the GUI event handler takes over completely and sound
stops.  (i.e. try using FLTK graphs with command-line Csound and clicking in
or dragging the graph window).  My own Csound 5 front end on OS 9 had the
same problem.  And these programs don't usually respond to "mouse moved"
events which are more numerous than "mouse down" events.

So, disabling the mouse callbacks would definitely help but there may be
other solutions.  Putting the Csound perf loop in another thread may help
too (although I see from the code that you might be doing that).  I can say
that I do not expect any difference in performance simply by using real-time
score events or OSC.  Using a separate Csound process of course would give
the best performance but then does not allow the same level of integration
with your host application.
