Do I need to install anything to use iO-808?

Updated

No. iO-808 (io808.com) is a fully recreated web-based TR-808 drum machine built with React, Redux, and the Web Audio API, so it runs directly in your browser. There is no download, no installer, and no physical drum machine required — you just need a modern browser that supports the Web Audio API.

What that means in practice

Because iO-808 is browser-based, the entire instrument lives on the page. Opening the site loads the interface and the audio engine together, so you can start programming patterns without setting anything up on your machine.

  • No software install — nothing to download or add to your system.
  • No hardware — you don't need an actual TR-808 or any MIDI controller to use it.
  • No account step mentioned — the available site information doesn't describe a sign-up or login requirement, so treat access as simply visiting the page.

The one real requirement: a modern browser

iO-808 relies on the Web Audio API to generate sound. That API is what lets the browser synthesize the drum sounds in real time instead of playing back pre-recorded files. Any current version of the major browsers supports it, so the practical condition is simply keeping your browser reasonably up to date.

If sound doesn't play, the usual cause is browser-side rather than a missing install:

  • The browser is too old to support the Web Audio API.
  • Audio is blocked until you interact with the page (a common browser autoplay policy) — click or tap the interface first.
  • The tab or system volume is muted.
