#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.;
