Optional options: RecursivePartial<DuoSynthOptions>Readonly contextThe context belonging to the node.
Set this debug flag to log all events that happen in this class.
Readonly detuneReadonly frequencyHarmonicity is the ratio between the two voices. A harmonicity of 1 is no change. Harmonicity = 2 means a change of an octave.
const duoSynth = new Tone.DuoSynth().toDestination();
duoSynth.triggerAttackRelease("C4", "2n");
// pitch voice1 an octave below voice0
duoSynth.harmonicity.value = 0.5;
The instrument only has an output
Readonly nameInvoked when the release has finished and the output is silent.
The glide time between notes.
The amount of vibrato
the vibrato frequency
Readonly voice0the first voice
Readonly voice1the second voice
The volume of the output in decibels.
const amSynth = new Tone.AMSynth().toDestination();
amSynth.volume.value = -6;
amSynth.triggerAttackRelease("G#3", 0.2);

The number of seconds of 1 processing block (128 samples)
console.log(Tone.Destination.blockTime);
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 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 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".
Indicates if the instance was disposed. 'Disposing' an instance means that all of the Web Audio nodes that were created for the instance are disconnected and freed for garbage collection.
The number of inputs feeding into the AudioNode. For source nodes, this will be 0.
const node = new Tone.Gain();
console.log(node.numberOfInputs);
The number of outputs of the AudioNode.
const node = new Tone.Gain();
console.log(node.numberOfOutputs);
The duration in seconds of one sample.
Connect the output of this node to the rest of the nodes in series.
Rest ...nodes: InputNode[]const player = new Tone.Player("https://tonejs.github.io/audio/drum-samples/handdrum-loop.mp3");
player.autostart = true;
const filter = new Tone.AutoFilter(4).start();
const distortion = new Tone.Distortion(0.5);

Get the object's attributes.
const osc = new Tone.Oscillator();
console.log(osc.get());
Set multiple properties at once with an object.
const filter = new Tone.Filter().toDestination();
// set values using an object
filter.set({
frequency: "C6",
type: "highpass"
});
const player = new Tone.Player("https://tonejs.github.io/audio/berklee/Analogsynth_octaves_highmid.mp3").connect(filter);
player.autostart = true;
Set the note at the given time. If no time is given, the note will set immediately.
The note to change to.
Optional time: Unit.TimeThe time when the note should be set.
const synth = new Tone.Synth().toDestination();
synth.triggerAttack("C4");
// change to F#6 in one quarter note from now.
synth.setNote("F#6", "+4n");
Sync the instrument to the Transport. All subsequent calls of triggerAttack and triggerRelease will be scheduled along the transport.
const fmSynth = new Tone.FMSynth().toDestination();
fmSynth.volume.value = -6;
fmSynth.sync();
// schedule 3 notes when the transport first starts
fmSynth.triggerAttackRelease("C4", "8n", 0);
fmSynth.triggerAttackRelease("E4", "8n", "8n");
fmSynth.triggerAttackRelease("G4", "8n", "4n");
// start the transport to hear the notes
Tone.Transport.start();
Convert the incoming time to seconds. This is calculated against the current TransportClass bpm
const gain = new Tone.Gain();
setInterval(() => console.log(gain.toSeconds("4n")), 100);
// ramp the tempo to 60 bpm over 30 seconds
Tone.getTransport().bpm.rampTo(60, 30);
Trigger the attack of the note optionally with a given velocity.
The note to trigger.
Optional time: Unit.TimeWhen the note should start.
The velocity determines how "loud" the note will be.
const synth = new Tone.Synth().toDestination();
// trigger the note a half second from now at half velocity
synth.triggerAttack("C4", "+0.5", 0.5);
Static get
DuoSynth is a monophonic synth composed of two MonoSynths run in parallel with control over the frequency ratio between the two voices and vibrato effect.
