MiniTAP
MiniTAP is a browser extension that turns your keyboard into a live web sequencer. It runs in Chrome and gives you eight channels you can trigger on the beat, on keystrokes, or at random. The whole interface is built for hands-on control during a set, so you can drive patterns without reaching for a mouse.
Most sequencers stay inside one app. MiniTAP instead posts window message events to whatever tab you are controlling, with events like mt-beat and mt-channel-on that your page can listen for. That makes it a bridge between a step sequencer and any web experience you are building, from 3D scenes to generative visuals.
It fits live performers, VJs, and creative developers who want tempo-synced triggers inside the browser. The creator built it to control 3D graphics in real time and shipped the extension in about a week, with documentation for keyboard bindings and the Connection API on minitap.io.
