Fwd: csound and glade / pygtk

[James Bergstra]

You're right that there are many good ways to make a GUI app around csound. In
TamTam, we are using csound as a sound rendering library, within a pthread that
writes directly to ALSA.  These things are controlled by a C++ python module
that we import into TamTam.

Without a clear idea of the approach you've taken, or the problems you are
facing, I venture that the following tip:

If you are using multiple threads of python code, you should be aware of the
global interpeter lock (often called GIL).  To prevent gtk from hogging the GIL
while there are no events to handle, you might want to explore the functions
threads_init(), threads_enter(), and threads_leave() in gdk.
