Max Features

Time
Working with time is easier in Max than traditional programming because you use objects to create visual “timing machines” whose behavior you can see, hear, and modify as they operate.

Interactivity
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, controls the timing and transport of the timing example above. Learn More

Control
In Max everything can be connected to everything, because everything speaks numbers. Another way to say this is that modularity is a core design principle of everything in the software.

Extensibility
Max users extend the environment in every possible direction. As a by-product of their work with the software, passionate Max users have contributed thousands of objects written in C, Java, or Javascript back to the user community.
