Hierarchy

Constructor

new PluckSynth (
options?:RecursivePartial<PluckSynthOptions >
) => PluckSynth

Properties

attackNoise #

number

The amount of noise at the attack. Nominal range of [0.1, 20]

Range: 0.1 to 20

blockTime #

readonly Seconds

The number of seconds of 1 processing block (128 samples)

channelCount #

number

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 #

ChannelCountMode

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.

  • "max" - computedNumberOfChannels is the maximum of the number of channels of all connections to an input. In this mode channelCount is ignored.
  • "clamped-max" - computedNumberOfChannels is determined as for "max" and then clamped to a maximum value of the given channelCount.
  • "explicit" - computedNumberOfChannels is the exact value as specified by the channelCount.

channelInterpretation #

ChannelInterpretation

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 #

BaseContext

The context belonging to the node.

dampening #

Frequency

The dampening control. i.e. the lowpass filter frequency of the comb filter

Range: 0 to 7000

debug #

boolean

Set this debug flag to log all events that happen in this class.

disposed #

readonly boolean

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.

input #

undefined

The instrument only has an output

name #

"PluckSynth"

numberOfInputs #

readonly number

The number of inputs feeding into the AudioNode. For source nodes, this will be 0.

numberOfOutputs #

readonly number

The number of outputs of the AudioNode.

output #

OutputNode

release #

Time

The release time which corresponds to a resonance ramp down to 0

resonance #

NormalRange

The amount of resonance of the pluck. Also correlates to the sustain duration.

sampleTime #

readonly Seconds

The duration in seconds of one sample.

static version #

string

The version number semver

volume #

Param<"decibels" >

The volume of the output in decibels.


import { AMSynth } from "tone";
const amSynth = new AMSynth().toDestination();
amSynth.volume.value = -6;
amSynth.triggerAttackRelease("G#3", 0.2);

Methods

Connect the output of this node to the rest of the nodes in series.


import { Destination, Filter, Oscillator, Volume } from "tone";
const osc = new Oscillator().start();
const filter = new Filter();
const volume = new Volume(-8);
// connect a node to the filter, volume and then to the master output
osc.chain(filter, volume, Destination);
chain (
...nodes:InputNode []
) => this

connect #

connect the output of a ToneAudioNode to an AudioParam, AudioNode, or ToneAudioNode

connect (
destination:InputNode ,

The output to connect to

outputNum= 0:number ,

The output to connect from

inputNum= 0:number

The input to connect to

) => this

disconnect #

disconnect the output

disconnect (
destination?:InputNode ,

fan (
...nodes:InputNode []
) => this

get #

Get the object's attributes.


import { Oscillator } from "tone";
const osc = new Oscillator();
console.log(osc.get());
// returns {"type" : "sine", "frequency" : 440, ...etc}
get ( ) => PluckSynthOptions

static getDefaults #

import { FMSynth, Transport } from "tone";
const fmSynth = new FMSynth().toDestination();
fmSynth.volume.value = -6;
fmSynth.sync();
// schedule 3 notes when the transport first starts
fmSynth.triggerAttackRelease("C4", "8n", 0);
