Tone.OmniOscillator

↳ EXTENDS Tone.Source

Tone.OmniOscillator aggregates Tone.Oscillator, Tone.PulseOscillator, Tone.PWMOscillator, Tone.FMOscillator, Tone.AMOscillator, and Tone.FatOscillator into one class. The oscillator class can be changed by setting the type. omniOsc.type = "pwm" will set it to the Tone.PWMOscillator. Prefixing any of the basic types (“sine”, “square4”, etc.) with “fm”, “am”, or “fat” will use the FMOscillator, AMOscillator or FatOscillator respectively. For example: omniOsc.type = "fatsawtooth" will create set the oscillator to a FatOscillator of type “sawtooth”.

CONSTRUCTOR

new Tone.OmniOscillator (
frequency
,
type
)
frequency

The initial frequency of the oscillator.

type

The type of the oscillator.

type: String

DEFAULTS

{
frequency : 440 ,
detune : 0 ,
type : sine ,
phase : 0
}

EXAMPLE

var omniOsc = new Tone.OmniOscillator("C#4", "pwm");

Members

.width

NormalRange #

The width of the oscillator (only if the oscillator is set to “pulse”)

EXAMPLE

var omniOsc = new Tone.OmniOscillator(440, "pulse");
//can access the width attribute only if type === "pulse"
omniOsc.width.value = 0.2;
</>

.harmonicity

Positive #

Harmonicity is the frequency ratio between the carrier and the modulator oscillators. A harmonicity of 1 gives both oscillators the same frequency. Harmonicity = 2 means a change of an octave. See Tone.AMOscillator or Tone.FMOscillator for more info.

</>

.modulationFrequency

Frequency #

The modulationFrequency Signal of the oscillator (only if the oscillator type is set to pwm). See Tone.PWMOscillator for more info.

EXAMPLE

var omniOsc = new Tone.OmniOscillator(440, "pwm");
//can access the modulationFrequency attribute only if type === "pwm"
omniOsc.modulationFrequency.value = 0.2;
</>

.modulationIndex

Positive #

The modulation index which is in essence the depth or amount of the modulation. In other terms it is the ratio of the frequency of the modulating signal (mf) to the amplitude of the modulating signal (ma) – as in ma/mf. See Tone.FMOscillator for more info.

</>

.modulationType

String #

The type of the modulator oscillator. Only if the oscillator is set to “am” or “fm” types. see. Tone.AMOscillator or Tone.FMOscillator for more info.

</>

.partialCount

Number #

The partial count of the oscillator. This is not available on “pwm” and “pulse” oscillator types.

EXAMPLE

//set the maximum number of partials
osc.partialCount = 0;
</>

.partials

Array #

The partials of the waveform. A partial represents the amplitude at a harmonic. The first harmonic is the fundamental frequency, the second is the octave and so on following the harmonic series. Setting this value will automatically set the type to “custom”. The value is an empty array when the type is not “custom”. This is not available on “pwm” and “pulse” oscillator types.

EXAMPLE

osc.partials = [1, 0.2, 0.01];
</>

.phase

Degrees #

The phase of the oscillator in degrees.

</>

.sourceType

String #

The source type of the oscillator.

EXAMPLE

var omniOsc = new Tone.OmniOscillator(440, "fmsquare");
omniOsc.sourceType // 'fm'
</>

.spread

Cents #

The detune spread between the oscillators. If “count” is set to 3 oscillators and the “spread” is set to 40, the three oscillators would be detuned like this: [-20, 0, 20] for a total detune spread of 40 cents. See Tone.FatOscillator for more info.

</>

.type

String #

The type of the oscillator. Can be any of the basic types: sine, square, triangle, sawtooth. Or prefix the basic types with “fm”, “am”, or “fat” to use the FMOscillator, AMOscillator or FatOscillator types. The oscillator could also be set to “pwm” or “pulse”. All of the parameters of the oscillator’s class are accessible when the oscillator is set to that type, but throws an error when it’s not.

EXAMPLE

omniOsc.type = "pwm";
//modulationFrequency is parameter which is available
//only when the type is "pwm".
omniOsc.modulationFrequency.value = 0.5;

EXAMPLE

//an square wave frequency modulated by a sawtooth
omniOsc.type = "fmsquare";
omniOsc.modulationType = "sawtooth";
</>

.baseType

String #

The base type of the oscillator.

EXAMPLE

var omniOsc = new Tone.OmniOscillator(440, "fmsquare4");
omniOsc.sourceType // 'fm'
omniOsc.baseType //'square'
omniOsc.partialCount //4
</>

.count

Number #

The number of detuned oscillators

</>

.detune

Cents #

The detune control

</>

.frequency

Frequency #

The frequency control.
