I suggest that you model what you want to accomplish using Python. For example, use the Python opcodes to set up shared memory, route signals, etc. When you get something working that makes sense, the Python code can then be translated to C++ or C for greater efficiency. You can put the Python stuff into UDOs so it looks more like "csound".

Also, you could try using psyco (just in time compiler for Python) to see if it speeds your Python code up. In my algorithmic composition stuff I find that psyco sometimes produces a pretty big speedup (e.g. 3x or so) and other times does nothing at all.

Regards,
Mike
