+#X text 19 39 This patch has two sine wave oscillators \, one with
+linear envelopes \, the other with quartic ones which sound more uniform.
+The "toggle switch" at bottom selects between the two \, and the message
+boxes sweep the amplitude and frequency up and down.;
+#X text 366 257 LINEAR;
+#X text 555 249 QUARTIC;
+#X text 335 120 The two oscillators are below. In the quartic one \,
+for both the amplitude and the frequency \, we have to take the fourth
+root of the target value (which we get by taking square root twice.)
+Then we raise the line~ output to the fourth power by squaring twice
+(the *~ objects \, whose left and right inlets are the same.) The cost
+is mostly that of the four additional *~ objects.;
