Using ctcsound with csnd6

ctcsound is compatible with the python wrapper csnd6, generated by swig when building Csound. csnd6 needs Python 2, so this notebook runs under a Python 2 kernel.

Import the csnd6 module and create an object called 'csSwig' from the csnd6.Csound class.



In [1]:

    
import csnd6
csSwig = csnd6.Csound()

Get an opaque pointer to the csound instance created by the csSwig object:



In [2]:

    
csPointer = csSwig.GetCsound().__int__()

Import the ctcsound module and create an object called 'csct' from the ctcsound.Csound class, using the already existing opaque pointer to the csound instance as an argument:



In [3]:

    
import ctcsound
csct = ctcsound.Csound(pointer_=csPointer)

Now the csSwig object and the csct object are both tied to the same csound instance. Compile a csd file from the csSwig object...



In [4]:

    
csSwig.Compile("analogSynth01.csd")









    Out[4]:





0

and play it from the csct object.



In [5]:

    
csct.perform()









    Out[5]:





2

Reset the csound instance from the csSwig object:



In [6]:

    
csSwig.Reset()

Recompile the same csd file from the ctcs object...



In [7]:

    
csct.compile_("csound", "analogSynth01.csd")









    Out[7]:





0

and play it from the csSwig object.



In [8]:

    
csSwig.Perform()









    Out[8]:





2

Voilà!



In [9]:

    
csct.cleanup()









    Out[9]:
