+  * This sketch demonstrates how to create a simple synthesis chain that 
+  * involves controlling the value of a UGenInput with the output of 
+  * a UGen. In this case, we patch an Oscil generating a sine wave into 
+  * the amplitude input of an Oscil generating a square wave. The result 
+  * is known as amplitude modulation.
