Tone.MembraneSynth

↳ EXTENDS Tone.Instrument

Tone.MembraneSynth makes kick and tom sounds using a single oscillator with an amplitude envelope and frequency ramp. A Tone.OmniOscillator is routed through a Tone.AmplitudeEnvelope to the output. The drum quality of the sound comes from the frequency envelope applied during during Tone.MembraneSynth.triggerAttack(note). The frequency envelope starts at note * .octaves and ramps to note over the duration of .pitchDecay.

.toMaster ( )

#
↪ returns Tone.AudioNode

this

Connect ‘this’ to the master output. Shorthand for this.connect(Tone.Master)

↳ inherited from Tone.Instrument

.triggerAttackRelease ( )

#
note

The note to trigger.
duration

How long the note should be held for before triggering the release. This value must be greater than 0.

type: Time
time

When the note should be triggered.

type: Time
default: now
velocity

The velocity the note should be triggered at.

default: 1
↪ returns Tone.Instrument

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");
