Working with interactivity is easier in Max because you can design interfaces visually, and the interfaces are then part of the program itself. For example, control the timing and transport of the example on the Max Time feature page.
Max contains a rich set of user interface tools, including dials, buttons, menus, and text editors. At a deeper level, it’s possible to control the entire user experience with cross-platform support for full-screen interfaces, HI devices, Quicktime video, and an embedded web browser. You can even script Max to construct interfaces dynamically.
