SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

ValueTree is the core data model used to store plugin state in JUCE and Tracktion Engine. This skill provides standardized patterns for creating, updating, and persisting that state to simplify development and restoration across sessions.

Core Features & Use Cases

ValueTree creation, property management, and child-tree handling for plugin state
Binding and syncing with juce::CachedValue for safe, fast reads on the UI and audio threads
State restoration, undo integration, and listener-based state tracking for robust workflows

Quick Start

Create a ValueTree for plugin state, bind CachedValue properties to the state, and implement restoration from a saved ValueTree.

FAQPage Schema

How do I serialize and persist plugin state in JUCE ValueTree?▼

To serialize plugin state in JUCE ValueTree, you create a tree structure, populate it with properties, bind CachedValue objects for thread-safe reads, and implement state restoration from the saved tree.

What is the best way to bind CachedValue properties to a ValueTree for audio thread safety?▼

Binding CachedValue properties to a ValueTree provides fast, thread-safe reads on both UI and audio threads. This pattern syncs property values automatically, ensuring safe data access without lock contention during audio processing.

How do I integrate undo management with ValueTree state updates in Tracktion Engine?▼

Integrating undo management with ValueTree state updates involves using listener-based tracking and the UndoManager. This pattern captures state mutations, enabling robust undo and redo workflows for Tracktion Engine plugins.

Can I use ValueTree child-trees to manage complex hierarchical plugin state?▼

Yes, you can use ValueTree child-trees to handle complex hierarchical plugin state. The pattern supports creating nested child-trees and managing chain structures, allowing structured organization of extensive state data.

Does Tracktion Engine require ValueTree for state persistence across sessions?▼

ValueTree is the core data model for storing plugin state in JUCE and Tracktion Engine. It is required for robust state persistence, enabling seamless restoration of plugin parameters and hierarchical data across sessions.

Why does my ValueTree state restoration fail when reloading a JUCE plugin?▼

ValueTree state restoration fails when the saved tree structure or property types do not match the expected format. Implementing standardized restoration patterns ensures properties and child-trees are correctly repopulated.
