| Thanks for your swift reply, and sorry for double posting.
You do not need to import explicitly in XSI, all objects are created prior to the script executing, and if
you dir() you get a massive list of them.
No, I think the problem is deeper than this. Below is a minimal test program to show what I mean.
I'm defining a function 'poopfn' in the global python namespace. When I run this with standalone python
the line 'pyruni "print dir()"' prints out:
['__builtins__', '__doc__', '__file__', '__name__', 'csnd', 'csound', 'poopfn']
as expected.
However, when I run this from within XSI in the embedded python, I get
['__builtins__', '__doc__', '__name__']
ie it is not picking up the global namespace, perhaps only creating a local one?
Does this give you any more ideas?
Thanks again,
Mac

csound = csnd.CppSound()
csound.setPythonMessageCallback()

def poopfn(x):
return 2.0*x

>In your Python code, did you import all the XSI modules that you need? Even if Python embedded in an app that has a Python console or interpreter, you normally still need to import all modules you intend to use. Of course, I assume you have done this.
>Another thing is different styles of import. "from namespace import *" is not the same as "import namespace". In the former case, you call "function(args)" in the latter case you call "namespace.function(args)". Possibly inside SoftImage, one style is used and you are trying to call using the other style.
>However, it may additionally be the case that XSI has a dynamically built namespace. In other words, classes are defined at some point during run time, not in an import statement. If so, you need to find WHEN that happens. If you identify this and gain access to the class objects, you can dir them to see what methods are available. You can do a top-level 'dir()' to see what modules have been loaded or built.
>Also, of course, you could submit your question to SoftImage lists or forums.
