EZ Web Audio / createSequence

Function: createSequence() ​

createSequence(transport, options): Sequence

Defined in: packages/core/src/index.ts:1018

Create a Sequence that schedules arbitrary callbacks at musical time positions.

Sequences are tied to a Transport at creation and follow its lifecycle. Events are stored as beat positions, so live BPM changes automatically affect subsequent scheduling without re-scheduling.

Parameters ​

transport ​

Transport

The Transport to sync to

options ​

SequenceOptions

Sequence configuration (length, loop, initial events)

Returns ​

Sequence

Sequence instance

Example ​

typescript
import { createTransport, createSequence, createSound } from 'ez-web-audio'

const transport = await createTransport({ bpm: 120, timeSignature: [4, 4] })
const kick = await createSound('kick.mp3')

const seq = createSequence(transport, { length: '1m' })
seq.at('1:1:0', (time) => kick.playIn(time - ctx.currentTime))
seq.at('1:3:0', (time) => kick.playIn(time - ctx.currentTime))

transport.start()

// Change BPM — events adjust automatically
transport.bpm = 140
