# Maestro

A real-time conducting gesture recognition app. Wave your hand like a conductor — the app detects your beats and plays orchestral music in sync.

## Features

- **Beat detection** — physics-based algorithm detects the ictus (beat point) from hand motion via webcam. No templates, no recording required.
- **Performance mode** — load a MIDI score, conduct to advance through it beat by beat with live sheet music display
- **Test mode** — visualize your beat detection with a real-time speed graph and BPM readout
- **Orchestral audio** — high-quality soundfont samples (strings, brass, woodwinds, percussion)

## Download

Download the latest release for Mac (Apple Silicon):

👉 [Releases](../../releases/latest)

Open the `.dmg`, drag Maestro to Applications, and launch. No installation of any other software required.

> First launch: macOS may show an "unidentified developer" warning. Right-click the app → Open → Open to bypass it (one time only).

## How to use

1. Launch the app and complete the hand calibration (hold up your hand for a few seconds)
2. **Test Mode** — start conducting downstrokes to see beat detection and BPM
3. **Performance Mode** — select a piece, conduct an upbeat gesture to activate, then conduct to play through the score

## Building from source

Requires Node.js.

```bash
npm install
npm run build       # builds Maestro.app locally
npm run release     # builds and publishes to GitHub Releases
```
