I see. Shouldn't that be installed by default when installing csound?

Maybe I'm using the wrong version of python?

Ok, I see it now. Yes, you do need the csnd library, that is your link to the
API.
I think it came with my version of Csound (5.14)

it has to do with versions of Python and Csound. I have been struggeling with
this for a while.
My csnd.py is in site-packages of python2.7.
I am on OS X 10.5.8, which means I cannot use it with a Csound version
higher than 5.14.

BTW, does any of the samples work, like shapes.py?

Maybe there should be a compatibility matrix for versions of Csound, OS's,
Python, etc.

I tried both python 2.6 and 2.7 to no avail. But it works from inside winXound. Can't say why.

I haven't got time now but I will try these and let you know.

yes! A test script or something would be very helpful.

Best,

Hi Peiman,

if you mean overwriting values into a function table that was created within csound,  you can do it this way:

tbl = csnd.CsoundMYFLTArray()        # create an empty CsoundMYFLTArray object
tblSize = cs.GetTable(tbl.GetPtr(), n)   # make our object point to ftable n data
                                                            #  and return ftable n size
tblArray = csnd.doubleArray_frompointer(tbl.GetPtr(0)) # create a python array
                                                                                         # pointing to ftable n data

(or tblArray = csnd.floatArray_frompointer(tbl.GetPtr(0)) if you're using a float version of Csound).

Then you can use tblArray with bracket indices for reading and for writing as well.

You can even do some more sophisticated manipulations (slicing, matrix algebra, ...) using the numpy module, as described in my Csound Journal paper:

Do you know if there is a method for overwriting table indices in python?

One could easily make a loop to overwrite a whole table at run time. Would be very powerful indeed.

Best,
Peiman

Hi,

You just have to be careful not to do this from a separate thread, as
these operations are not thread safe. You will usually do them between
calls to csoundPerform.

Cheers,
Andrés
