The result is a gradual change in amplitude as the phases of the two slip against each other. This is called beating. More complex beating pattenrs may be made by using three or more oscillators. Also their amplitudes need not be equal (as they are here).; #X text 31 407 They are all summed using "+~" boxes. They could have been summed in any order ("+~" is commutative for practical purposes) but here they are added in pairs to emphasize the relationships between them.; #X text 30 474 In contrast to the previous example , the oscillators are not tuned to the overtone series (ratios 1:2:3:4...) and so the frequencies 330 , 440 , and 587 are heard separately.; #X connect 1 0 0 0; #X connect 1 0 0 1; #X connect 3 0 12 0; #X connect 4 0 12 1; #X connect 5 0 4 0; #X connect 6 0 3 0; #X connect 7 0 3 1; #X connect 8 0 4 1; #X connect 9 0 1 1; #X connect 10 0 9 0; #X connect 11 0 9 1; #X connect 12 0 1 0;

Here the four oscillators have frequencies in a 1:2:3:4 ratio (the three "*" objects compute the second , third , and fourth one). The amplitudes are adjusted by the "*~ 0.1" , etc. , objects. Note that , since the frequency (from the "mtof") is a message , a "*" box suffices to operate on it , but the oscillator's output , being an audio signal , needs "*~" instead. The control marked "overtones ON/OFF" is a toggle switch. Click to turn it on and off. Of the overtones are "off" you hear only a sinusoid from the forst oscillator. If on , you hear all four.; #X connect 0 0 1 0; #X connect 1 0 6 0; #X connect 1 0 7 0; #X connect 1 0 10 0; #X connect 1 0 12 0; #X connect 3 0 0 0; #X connect 6 0 14 0; #X connect 7 0 8 0; #X connect 8 0 30 0; #X connect 9 0 13 0; #X connect 10 0 9 0; #X connect 11 0 31 0; #X connect 12 0 11 0; #X connect 13 0 17 1; #X connect 14 0 2 0; #X connect 14 0 2 1; #X connect 14 0 27 0; #X connect 15 0 14 1; #X connect 16 0 15 1; #X connect 17 0 18 0; #X connect 18 0 15 0; #X connect 21 0 27 0; #X connect 30 0 17 0; #X connect 31 0 18 1;

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 obj 167 270 output~; #X text 489 613 updated for Pd version 0.37; #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.; #X connect 0 0 3 1; #X connect 1 0 22 0; #X connect 2 0 3 0; #X connect 3 0 14 0; #X connect 5 0 7 0; #X connect 8 0 0 1; #X connect 14 0 7 0; #X connect 14 0 25 0; #X connect 14 0 25 1; #X connect 22 0 0 0;
