📖 How to use it›
- Pick an instrument from the row above the grid — harp, bell, bass, drums, and more.
- Place notes. Click (or drag) on the grid. Higher rows = higher pitch; columns = time. Click a note again to remove it.
- Press Play. Adjust tempo, loop it, and tweak until it sounds right. Try a demo song to start.
- Export. Download a .nbs (open it in Note Block Studio and build it in your world), a .wav to share, or copy a link that reopens your song.
Pitches cover the two octaves an MC note block can play (F#3-F#5). The in-browser sound is a close synth preview; the exported .nbs uses the real note block instruments.
Describe a vibe and press Generate — a mood-aware composer builds it instantly (works offline), and your AI key is used when available.
