I have committed to Csound CVS a new examples/PythonDemoApp.py and PythonDemoFrame.py application. This demonstrates a number of techniques involved with effectively using the Csound’s Python API. This is not a real-time performance application, so much as it is a composition that plays in real time and enables the user to tweak synthesis parameters that affect the global sound of the piece, and even to edit the orchestra and score. All changes can be saved as progressive ‘snapshots’ which are restored when the application starts up again.
