	ctcsound is neither 'more effective' or 'less effective'.

	Ctctsound is much more powerful than the 'old' python API. With it you can directly read or write csound channels, and also tables. It can be used from any Python program (does not have to be a notebook or a GUI). Csound has to run on the same machine as your Python program, though. OSC is somewhat trickier, you have to keep track of variable types and there is somewhat more coding involved on both sides. A definite advantage of OSC is that your program does not have to be on the same computer as csound. On 23/07/18 17:49, Forrest Curo wrote: ctcsound is neither 'more effective' or 'less effective'.

	ctcsound was introduced in Csound 6.07. ctcsound works with Python2.x and Python3.x as well, and it uses the numpy ndarray data format to point to Csound tables and channels, giving the user the opportunity to use easily the scientific computing python environment developed around numpy and scipy. csnd6 is still delivered with each Csound 6.0x release where x is greater than or equal to 7. However, it is recommended to use ctcsound instead, because csnd6 might become obsolete in the next major release of Csound (7.xx).

	ctcsound is just another wrapper from python to the Csound API, so it can do everything csnd6 does (and some more). You can have a look at the coobooks here: https://github.com/fggp/ctcsound/tree/master/cookbook, you can look at the examples here: https://github.com/csound/csoundAPI_examples/blob/master/python/CtcsoundAPIExamples.ipynb, you can read the examples in this book written by Victor: https://www.springer.com/gp/book/9783319635033. And, of course, you can look at the code itself which is fully documented like any other python module.

	So now libcsound64.so is found but you're using a version of ctcsound that is more recent than the one shipped with the Csound package you've installed. In fact, if some new functions are added to the Csound API, ctcsound is changed accordingly in Github. csoundCompileTreeAsync was added in Csound6.10. It seems that the Csound package you've installed is older than 6.10. So csoundCompileTreeAsync is referenced in the ctcsound module you're using but it is not found in the libcsound64.so shared library installed by the Csound package. You should replace the ctcsound.py file in your /home/pi/.local/lib/python.3.5/site-packages/ directory by the ctcsound.py file shipped within the Csound package you've installed.
