I do hope I'm not already cluttering the mailing list with all my questions....
I do not understand why I get Csound tidy up: Segmentation fault :

Your program crashed.

Maybe you should learn a bit more about Csound and its language before trying to use the API. Look at the resources in csound.com, the FLOSS manual is a good place to start. Try getting used to running Csound first without actually embedding it in
your own program, then when you understand how it works, look at the API examples.
