+Most functions that send messages to the server do so by accepting a socket type as the first argument.
 This function is passed to with-udp-sc3 or with-tcp-sc3, which call the function on a socket of a specific type.

 with-udp-sc3 opens a udp socket, calls func on that socket, closes the socket, and returns the return value of func.

+The same as audition but without the socket creation step. (audition uses play)
+
+Using the given socket, plays sound generated by the ugen. This creates a synthdef,
+sends it to the server using the name "anonymous" and group 1, and creates a new synth.
