Used to create functions like sum numbers, conversion between data (svg to scores, for example), etc. These objects are the simpler but more useful, you create them using pd.add_objectorpd.new_object. Inside the folder resources of thepy4pdcode you will find a lot of examples of these objects, we also have some py4pd libraries, likepy4pd-upic,py4pd-ji,py4pd-freesound,py4pd-partials`.
