I'm having problems getting the Python to actually work. No problem loading Python and calling the Python API dynamically. The problem comes when actually running Python scripts. Code that works in CsoundVST doesn't work in csound5gui. Probably the threading or message callback stuff is too different.

At this point, we can fix this or just revert to csound5gui without Python. I'm happy either way, I'd like to know what others think.

Regards,
Mike
