Fm Mode - Native Instruments Absynth 5 Reference Manual

•
Phase control: Sets the phase of the Oscillator. The effect is only audible if a second
Oscillator is active. This parameter is useful when using integer values for frequency ratios
between carrier and modulator, as is the case in FM.
An Oscillator in Double mode uses less CPU power than two Oscillators in Single mode.

5.4.5 FM Mode

Oscillator in FM mode
Frequency modulation was discovered in the late 1960's by John Chowning and achieved
great popularity in the 1980's through Yamaha's DX7 synthesizer. Much has already been
written about FM synthesis so we will not go into detail here.
In FM mode, the Mod oscillator modulates the frequency of the Main oscillator.
On the Main panel, you find the same parameters as in Single mode. For more details, please
refer to the section 5.4.3, "Single Mode"
On the Mod panel, the following parameters are available:
•
FM Index: This determines the depth of the Frequency Modulation.
•
Waveform Selector: Clicking the Waveform Selector allows you to choose the Waveform
for the oscillator (see section
above for details).
•
Frequency menu and Frequency control: Enables you to enter the oscillator's frequency as
a transposition of the played note (Trans), as a relationship (Ratio) with the played note,
as a fixed Frequency (Hz) or via a fixed MIDI note (Note). See section
Menu and Frequency
above.
