#X text 475 452 To do phase modulation \, we split a "carrier oscillator"
into its phase calculation (phasor~) and its waveform lookup (cos~).
These together would be equivalent to an osc~ object \, but the "+~"
between them adds anopther oscillator's output to the phase.;
#X text 475 530 You will get the best graphs by choosing reasonably
low carrier and modulation frequencies (50-100 \, say). The modulation
index is usually between 0 and 1 (which means the control will typically
range from 0-100).;
