This example also demonstrates how object arguments are handled.
The functionality of the jstest1 patch could be easily achieved using the Max scale or expr objects. However, something that would not be so easily handled by normal Max objects would be the use of the lastIn and/or lastOut variables in the scaling computation.
Tutorial #2 demonstrates the ability to dynamically create and inter-connect Max objects in a patch. It also shows how to use methods to handle custom messages coming from the patcher.
Tutorial #4 focuses on the use of the jsui object, which allows for the design of graphical user interface objects, with support for two- and three-dimensional vector graphics drawn with OpenGL commands, as well as support to handle mouse interactions in the jsui object window.
