How to use a MIDI keyboard online
Noodler turns a MIDI controller into an instrument in your browser. You do not need to install a DAW, a driver or a plugin.
1. Connect your keyboard
Plug in a USB or Bluetooth MIDI keyboard, or use your computer keyboard with the on-screen keys.
2. Choose a sound
Select a built-in instrument such as grand piano, electric piano, synth, bass or strings.
3. Play, record and share
Play with low-latency browser audio, record your take, trim it and share a link when you are ready.
For the lowest latency, use a desktop browser such as Chrome or Edge with wired headphones or speakers.
Frequently asked questions
Is Noodler free?
Yes. Noodler is completely free and runs in your browser — no account, no download, no plugins.
Do I need a MIDI keyboard?
No. You can play with your computer keyboard or the on-screen keys, but a USB or Bluetooth MIDI controller gives you the full experience.
Do I have to install anything?
No. Noodler is a web app — everything runs in the browser. There is nothing to install and no plugin to load.
What instruments can I play?
Over 90 instruments, including grand piano, electric piano, strings, synths, bass, brass, mallets and drum-pad kits.
Can I record and share what I play?
Yes. Record your session, trim it, and share it with a link so anyone can play it back in their browser.
Can I record a microphone or guitar?
Yes. Choose your audio input in Settings to play and record it in the browser. Use headphones to avoid feedback.
Is Noodler a DAW?
Yes, a basic one. Record MIDI and audio takes on a multitrack timeline, build loops in layers, and download audio or MIDI. For mixing and plugins, use a full DAW.
Does it work on mobile?
Yes. On phones you get a swipeable keyboard and recording; MIDI and audio inputs work best on desktop.
Why is there a slight delay between playing and hearing the sound?
The most likely cause is Bluetooth headphones or earbuds (such as AirPods). Bluetooth buffers and re-encodes audio before sending it wirelessly, which adds roughly 100–300 ms of latency that no web app can remove. For the tightest timing, switch to wired or built-in speakers or headphones.
