How do Wigout and TrikTraks compose waveforms?

Both Wigout and TrikTraks use elements that are joined together to form states.

An element has a duration and an amplitude.

Its duration is specified in samples, and its amplitude is a number between +32767 and -32768.

The waveform described above, has four elements:

After defining your elements, you define a state that uses your elements. The state defined above is:

And it looks like this:

\scalebox {0.6}{\includegraphics*{graphics/square2.eps}}

The same four elements could be used to define a different state:

And the waveform would look like this:

\scalebox {0.6}{\includegraphics*{graphics/square3.eps}}

These two steps are the fundamentals for using both Wigout and TrikTraks:

The rest of this introduction describes how the information contained in elements and states is converted into frequency and loudness.
