Adapter-Pluggable daw-editor

Summary

<daw-editor> is now adapter-agnostic — consumers provide their own PlayoutAdapter (NativePlayoutAdapter or TonePlayoutAdapter). No default adapter or AudioContext created internally.

Published Packages

Package	Version	Change
@waveform-playlist/engine	13.0.0	Breaking: ppqn required on PlayoutAdapter, adapter is source of truth
@waveform-playlist/playout	12.1.0	TonePlayoutAdapter gains tempo/meter, cross-context worklet bridge
@waveform-playlist/worklets	12.1.0	addRecordingWorkletModule / addMeterWorkletModule (SAC pattern)
@waveform-playlist/recording	12.0.1	Internal: uses new worklet helpers
@dawcore/components	0.0.12	Breaking: adapter required, transport getter removed, sample-rate attribute removed
@dawcore/transport	0.0.9	Exposes audioContext and ppqn getters

Highlights

• Adapter pluggability — choose between Native Web Audio (multi-tempo, multi-meter, metronome) and Tone.js (effects, MIDI synths)
• PPQN driven by adapter — adapter is the source of truth for tick resolution; setPpqn?() lets the editor request, adapter decides
• Cross-context worklet support (SAC pattern) — recording works with both adapters via callback injection for addModule and optional createAudioWorkletNode/createMediaStreamSource on the adapter
• Examples restructured — examples/dawcore-native/ and examples/dawcore-tone/ with basic, multiclip, beats-grid, and recording pages
• Independent versioning — packages now follow their own semver based on actual changes

Breaking Changes (dawcore 0.0.x)

• editor.adapter = new NativePlayoutAdapter(new AudioContext()) required before use
• editor.transport removed — use adapter.transport directly
• editor.audioContext setter removed — context comes from adapter
• sample-rate attribute removed — rate determined by adapter's AudioContext

Migration

// Before
import '@dawcore/components';
// editor auto-created AudioContext + NativePlayoutAdapter

// After
import '@dawcore/components';
import { NativePlayoutAdapter } from '@dawcore/transport';

const editor = document.querySelector('daw-editor');
editor.adapter = new NativePlayoutAdapter(new AudioContext());
