The modulators modulate the frequency of the previous oscillator. Frequency modulation adds new overtones to the sound. Simple ratios i.e. frequencies that are integer multiplications of the carriers frequency, will generally produce overtones that align to the harmonic series. More complex ratios will produce inharmonic overtones. This is an effective way of quickly making a very complex tone.",
