| The definition of the method is:
def set_filechannel(self,chan,name):
"""overrides the base method, setting the channel string"""
if not self.ready:
self.csound.SetChannel(chan,name)
else:
BasicGUI.set_filechannel(self,chan,name)
So, what happens is that if the variable 'ready' is True, this uses
the base class method (ie. does not call
SetChannel). Maybe that is the problem.
'ready' becomes True after a successful compilation using CsoundGUI.
compile() or CsoundGUI.csd()
or CsoundGUI.recompile().
