+#X text 53 443 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 54 332 This patch 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 55 526 The component frequencies are equal to the carrier frequency
+\, plus or minus multiples of the modulator frequency. A more complete
+discussion of FM occurs in part 5 of this series.;
