+#X text 52 363 This shows the classical FM synthesis technique developed
+by John Chowning. It's nothing but an oscillator with vibrato controlled
+by another "modulation" oscillator. First \, to understand the patch
+\, set carrier frequency to 400 or so \, modulation frequency between
+5 and 10 \, and try modulation index values between 0 and 400 \, say.
+You'll hear a sine wave with vibrato.;
+#X text 531 172 --- 0.01 seconds ----;
+#X text 51 478 To get the FM sound \, set all three of carrier frequency
+\, modulation frequency \, and modulation index in the hundreds. Note
+that you get a timbral change as you sweep modulation index \, because
+this changes the amplitudes of the components of the output sound but
+not their frequencies.;
+#X text 48 564 The component frequencies are equal to the carrier frequency
+\, plus or minus multiples of the modulator frequency.;
