Is it really not possible to create a sound track through python?

phillipg

So from what I understand the BaseSound class is only accessible through the c++ api? I've managed to load files into a sound track with python, but only after manually creating the track myself, which obviously isn't ideal. Is there a reason for this, or could this possibly be added in the future? I understand sound stuff isn't really that high on the list of requested features to be fair lol.

About your First Question

I am not quite sure where you came across the information that it would be impossible to do this, but you can allocate and add a sound track just as any other special track as documented. Please post your code for future support requests.
