Some time ago, I wrote an example of how to do this, which can be found in "examples/trapped.py". I just now tried it, and it still works fine.

Regards,
Mike

Yes thanks Michael,

Just glanced at Trapped but as i explained in my previous post, trapped.py
also uses separate csound.setOrchestra() & csound.setScore() statements &
not a unified CSD.

i have run several python scripts sucessfully using this orc/sco model, but
am yet to run one with a CSD nested within it.

so the query i'm afraid still stands

thanks 

Tim
