+Use the `buffer(int frameNumber)` method to return the internal `PGraphics` object that contains the specific frame of soundtrack data specified by the frameNumber. You can then draw onto the canvas, address the pixels directly, or as in the provided BufferExample.pde assign the image data to a PImage to be manipulated using the built-in transformation methods.
