Brick Beat

Develop an interactive browser-based 3D music sequencer named Brick Beat. First, build a core interactive 3D beat board interface where users can snap and remove colorful LEGO-style bricks via click or tap operations, with no prerequisite music theory required for end users. Set up four dedicated instrument tracks covering Drums, Bass, Keys and Perc, add two instrument switching methods: number keys 1 to 4 and on-screen functional buttons, to support users toggling between tracks freely.
Integrate a play function that enables pattern looping, with real-time lighting effects for each active step during playback. Implement 3D orbit interaction that allows users to drag the board to view their created sequence from any angle. Use Web Audio API to realize live in-browser audio synthesis, ensure no external sound files are needed for the entire audio playback process. Add a built-in beat visualizer that dynamically responds to beat intensity while the loop is running, to enhance the interactive experience. Make sure all functions run smoothly in mainstream browsers, with clear operation feedback for every user action to guarantee a low-threshold, friendly creative experience for users of all skill levels.
