FM Type<br />
A. Linear FM types<br />
lin 2 > 1<br />
Oscillator 2 is added to the phase of oscillator 1. Linear FM is the<br />
style used by typical FM music synthesizers. Modulating a sine<br />
wave with another, higher-frequency sine wave produces a<br />
fundamental frequency with a variety of overtones, and this can be<br />
used to reproduce the sounds of many physical musical<br />
instruments.<br />
lin 2+3 > 1<br />
Oscillators 2 and 3 are added to the phase of oscillator 1.<br />
lin 3 > 2 > 1<br />
Oscillator 3 is added to the phase of oscillator 2. The resultant<br />
waveform is added to the phase of oscillator 1.<br />
With linear FM, the FM Amount controls the “modulation index”,<br />
with a level of 100% providing an index of 32.<br />
B. Exponential FM types<br />
exp 2 > 1<br />
Oscillator 2 modulates the pitch of oscillator 1.<br />
exp 3 > 2 > 1<br />
Oscillator 3 modulates the pitch of oscillator 2. The resultant<br />
waveform modulates the pitch of oscillator 1.<br />
With exponential FM, the FM Amount controls the range of pitch<br />
modulation, with a level of 100% driving the pitch up and down a<br />
full six octaves.<br />
