+#X text 4 408 This patch splits a sawtooth wave into its even and odd
+harmonics. The wrap~ object is used to make the phased copy. Adding
+and subtracting this to and from the original gives the results shown
+and heard. (Listen to the two outputs separately \, then together.)

+#X text 4 491 This is a classic technique for gaining separate control
+over the even and odd harmonics in a synthetic sound. It can also be
+used conceptually to understand the harmonic content of a square wave
+in terms of that of a sawtooth \, or vice versa.;
