Show HN: I Built a Sequencer for the Web
Hey HN!<p>Last week I was working on a website and needed a way to synchronise visuals with live music.<p>I&#x27;ve used MIDI controllers for this before, but I am travelling right now and don&#x27;t have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it.<p>It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh).<p>Features:<p>- Works as a browser extension. Atm distributed through chrome web store only.<p>– 8 customisable channels. Each channel has 3 modes: sequencer, keystroke and random.<p>- It sends post messages to the current page. Use however you want.<p>- Works with your keyboard. The key bindings are designed for expressive live usage.<p>- Advanced tempo controls. Easy to synchronise with live music using the ‘tap temp’ feature.<p>- Open Source, all code in github.<p>Anyway, let me know what you think.
