4. Use?
   - as a prototyping language and a sound
   engine. The table interface called the
   Reactable and the iPhone app RjDj both
   embed Pd as a sound engine
   - prototyping audio for video games by a
   number of audio designers. (For example,
   EAPd is the internal version of Pd that is used
   at Electronic Arts (EA). It has also been
   embedded into EA Spore)

8. Patches
   - patches are developed graphically.
   Algorithmic functions are represented by
   objects, placed on a screen called canvas.
   - Objects are connected together with cords,
   and data flows from one object to another
   through this cords.
   - Each object performs a specific task, from
   very low level mathematic operations to
   complex audio or video functions.

9. Object Types
   - built-in Pd objects;
   Object, Message, Symbol, Number,...
   - abstractions, that is, reusable patches
   created in Pd itself;
   - externals, i.e. objects developed in another
   programming language.
