Tone.AMSynth
↳ EXTENDS Tone.MonophonicAMSynth uses the output of one Tone.Synth to modulate the amplitude of another Tone.Synth. The harmonicity (the ratio between the two signals) affects the timbre of the output signal greatly. Read more about Amplitude Modulation Synthesis on SoundOnSound.
CONSTRUCTOR
new Tone.AMSynth ( [the options available for the synth see defaults below
DEFAULTS
EXAMPLE
var synth = new Tone.AMSynth().toMaster();
synth.triggerAttackRelease("C4", "4n");Members
.harmonicity
↝ Positive #Harmonicity is the ratio between the two voices. A harmonicity of 1 is no change. Harmonicity = 2 means a change of an octave.
EXAMPLE
//pitch voice1 an octave below voice0
synth.harmonicity.value = 0.5;.modulation
↝ Tone.Oscillator #The modulator’s oscillator which is applied to the amplitude of the oscillator
.channelCount
↝ Number READONLY #channelCount is the number of channels used when up-mixing and down-mixing connections to any inputs to the node. The default value is 2 except for specific nodes where its value is specially determined.
.channelCountMode
↝ String READONLY #channelCountMode determines how channels will be counted when up-mixing and down-mixing connections to any inputs to the node. The default value is “max”. This attribute has no effect for nodes with no inputs.
.channelInterpretation
↝ String READONLY #channelInterpretation determines how individual channels will be treated when up-mixing and down-mixing connections to any inputs to the node. The default value is “speakers”.
.context
↝ Tone.Context READONLY #Get the audio context belonging to this instance.
.numberOfInputs
↝ Number READONLY #The number of inputs feeding into the AudioNode. For source nodes, this will be 0.
.numberOfOutputs
↝ Number READONLY #The number of outputs coming out of the AudioNode.
.volume
↝ Decibels #The volume of the output in decibels.
EXAMPLE
source.volume.value = -6;Methods
.toMaster ( )
#this
Connect ‘this’ to the master output. Shorthand for this.connect(Tone.Master)
EXAMPLE
//connect an oscillator to the master output
var osc = new Tone.Oscillator().toMaster();.connect ( )
#optionally which output to connect from
optionally which input to connect to
this
connect the output of a ToneNode to an AudioParam, AudioNode, or ToneNode
.disconnect ( )
#Either the output index to disconnect if the output is an array, or the node to disconnect from.
this
disconnect the output
.fan ( )
#this
connect the output of this node to the rest of the nodes in parallel.
.chain ( )
#this
Connect the output of this node to the rest of the nodes in series.
EXAMPLE
//connect a node to an effect, panVol and then to the master output
node.chain(effect, panVol, Tone.Master);
.unsync ( )
#this
Unsync the instrument from the Transport
.sync ( )
#this
Sync the instrument to the Transport. All subsequent calls of triggerAttack and triggerRelease will be scheduled along the transport.
EXAMPLE
instrument.sync()
//schedule 3 notes when the transport first starts
instrument.triggerAttackRelease('C4', '8n', 0)
instrument.triggerAttackRelease('E4', '8n', '8n')
instrument.triggerAttackRelease('G4', '8n', '4n')
//start the transport to hear the notes
Transport.start().triggerAttackRelease ( )
#The note to trigger.
How long the note should be held for before triggering the release. This value must be greater than 0.
When the note should be triggered.
The velocity the note should be triggered at.
this
Trigger the attack and then the release after the duration.
EXAMPLE
//trigger "C4" for the duration of an 8th note
synth.triggerAttackRelease("C4", "8n");.triggerAttack ( )
#The note to trigger.
When the note should start.
velocity The velocity scaler determines how “loud” the note will be triggered.
this
Trigger the attack of the note optionally with a given velocity.
EXAMPLE
synth.triggerAttack("C4");
EXAMPLE
//trigger the note a half second from now at half velocity
synth.triggerAttack("C4", "+0.5", 0.5);.getLevelAtTime ( )
#The time to query the envelope value
The output level between 0-1
Get the level of the output at the given time. Measures the envelope(s) value at the time.
.triggerRelease ( )
#If no time is given, the release happens immediatly
this
Trigger the release portion of the envelope
EXAMPLE
synth.triggerRelease();.setNote ( )
#The note to change to.
The time when the note should be set.
this
Set the note at the given time. If no time is given, the note will set immediately.
EXAMPLE
//change to F#6 in one quarter note from now.
synth.setNote("F#6", "+4n");EXAMPLE
//change to Bb4 right now
synth.setNote("Bb4");
