FM oscillator parameters<br />
••<br />
Vibrato knob: Rotate to set the amount of vibrato (pitch modulation).<br />
••<br />
Modulation knob: Rotate to choose an FM amount modulation source, and to set the<br />
modulation intensity.<br />
••<br />
FM (Amount) slider: The carrier waveform is a simple sine wave. Drag to adjust the level of this<br />
basic tone.<br />
••<br />
FM/Harmonic switch: Switch to control the harmonic/inharmonic content of your sound with<br />
the LFO or Filter Envelope.<br />
••<br />
The left switch position lets you use the LFO or Filter envelope to modulate the FM<br />
(Amount).<br />
••<br />
The middle switch position lets you use the LFO or Filter envelope to modulate the FM<br />
(Amount) and Harmonic content at the same time.<br />
••<br />
The middle switch position lets you use the LFO or Filter envelope to modulate the<br />
Harmonic content.<br />
••<br />
Harmonic/Inharmonic sliders: Drag the Harmonic and Inharmonic sliders to precisely change<br />
the levels of these sonic elements, and therefore, the tonal color of your sound. Technically,<br />
you are changing the tuning ratio between the carrier and modulator oscillators, resulting in<br />
harmonic or inharmonic content becoming more or less audible.<br />
Note: The tuning ratio can change significantly when you adjust the (Wave) Shape slider,<br />
so avoid using it if making a subtle alteration to the harmonic or inharmonic content of<br />
your sound.<br />
••<br />
(Wave) Shape slider: Drag to modulate the carrier waveform. This control and the FM slider<br />
interact as you adjust either, resulting in a range of tones with more or less harmonic/<br />
inharmonic content.<br />
••<br />
Mix slider: Move to crossfade (set the level relationships) between the modulator and<br />
carrier oscillators.<br />
