Both these matrix examples are very small and simple. In practice, most scanned synthesis instruments will use many more masses than four, so their matrices will be much larger and more complex. See the example in the <link linkend="scans"><citetitle>scans</citetitle></link> documentation.

Please note that the generated dynamic wavetables can be very unstable. Certain values for masses, centering, and damping can cause the system to <quote>blow up</quote> and the most interesting sounds to emerge from your loudspeakers!
