Haunted Beat: Make Beats Together
Tap a grid with others in real time. Five spooky presets get you started. Export your beat as video.
You want to make electronic music with friends without needing software or files. Haunted Beat is a web sequencer where every person who opens it sees and shapes the same 16-step drum grid. Tap any cell to place a drum hit. Everyone sees it happen instantly. Five Halloween-themed presets—Nocturna, Crypt Crawl, Full Moon, Cursed 808, and Witches' Bash—show what grooves feel right. Adjust the tempo from 70 to 160 BPM. Watch a feed of who hit what, and when you are happy, export the result as a video.
What it does
The app shows a 4-by-16 grid. Each row is a drum sound: kick, snare, hi-hat, clap, and more, including a ghost sound. Each column is a sixteenth-note step. Tap a cell to toggle a hit. When you play, the grid pulses to the beat and plays back all the hits everyone has placed. A side panel shows recent community activity with names and timestamps. Preset buttons load ready-made drum patterns and set the tempo. A video export tool captures 4, 8, or 16 bars with all hits and lets you download it.

The latest update makes each grid cell look and dance like a pumpkin that bops to the beat, replacing the plain card look with a spooky Halloween visual theme.
How it differs from Community Beat
Haunted Beat is a Halloween remix of Community Beat. It adds five spooky drum presets and replaces the generic grid cells with dancing pumpkin graphics that move to the rhythm, turning an abstract sequencer into a festive group experience.
