+#X text 13 430 A patch to split a sawtooth into even and odd harmonics
+ala Buchla. The wrap~ object folds its input into the interval [0 \,
+1) so taht \, for instance \, subtracting 1/5 from a phasor and wrapping
+it gives another phasor a half cycle out of phase frmo the original.
+Adding and subtracting the two give the results shown and heard. (Listen
+to the two outputs separately \, then together.);
