MonoSynth

MonoSynth is composed of one oscillator, one filter, and two envelopes. The amplitude of the Oscillator and the cutoff frequency of the Filter are controlled by Envelopes. 


const synth = new Tone.MonoSynth({
	oscillator: {
		type: "square"
	},
	envelope: {
		attack: 0.1
	}
}).toDestination();
synth.triggerAttackRelease("C4", "8n");

Constructor

new MonoSynth (
options?:RecursivePartial<MonoSynthOptions >
) => MonoSynth

Properties

blockTime #

readonly Seconds

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


console.log(Tone.Destination.blockTime);

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".

frequency #
