SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill simplifies the integration of MIDI hardware with web applications, enabling interactive music experiences and control interfaces directly in the browser.

Core Features & Use Cases

MIDI Input Management: Handles connection, disconnection, and message parsing for MIDI devices.
Event Handling: Emits custom events for note-on, note-off, control change (CC), and MIDI clock.
Mapping & Routing: Provides patterns for mapping MIDI notes to UI elements and routing messages based on device.
Use Case: Integrate a MIDI controller to control parameters in a web-based audio synthesizer or trigger samples in a drum machine application.

Quick Start

Use the midi-web skill to initialize the MidiManager and listen for 'noteOn' events.

FAQPage Schema

How do I connect a MIDI controller to a web browser using JavaScript?▼

To connect a MIDI controller in JavaScript, you use Web MIDI API functionality to handle device connections, parse incoming messages, and emit custom events for real-time parameter control. This enables interactive music experiences directly in the browser.

How do I map MIDI CC messages to control web audio parameters in TypeScript?▼

MIDI CC messages can be mapped to web audio parameters using TypeScript by implementing event handling patterns that listen for control change events and route them to specific synthesizer controls. This allows real-time parameter manipulation from hardware devices.

How do I handle MIDI note-on and note-off events for a web drum machine?▼

Handling MIDI note events for a web drum machine involves listening for note-on and note-off events from the Web MIDI API. You can convert MIDI notes to pad indices to trigger specific samples within your browser-based application.

Can I route MIDI messages from multiple devices simultaneously in a web app?▼

Yes, you can route MIDI messages from multiple devices simultaneously by implementing multi-device routing patterns. This manages connections across several hardware controllers and directs messages based on the originating device.

Does the Web MIDI API support TypeScript for browser-based music applications?▼

The Web MIDI API supports TypeScript for browser-based music applications by providing structured patterns for MIDI input management, event handling, and mapping. This simplifies hardware integration for interactive web audio projects.

What is the best way to manage MIDI device disconnections in a web audio app?▼

Managing MIDI device disconnections in a web audio app requires implementing MIDI input management that detects when hardware is unplugged. This ensures your application gracefully handles connection state changes without crashing.
