batch_wavegen() call issue

[Latzy47]

Hey,
I was about to execute the synthesis.py file and came across some TypeError's.
With a closer look at this line you can see the keyword argument 'initial_value'. Though in the definition of the batch_wavegen() function there is no keyword argument 'initial_value', instead wavegen() has it. Changing batch_wavegen to wavegen just works fine.
I just want to hint at this issue.

Feel free to ignore this if the line is intended as it is.
Regards
