Beat Lab
Build a beat, jam a lead over it, share your loop with a link.
- Press play — a beat is already looping.
- Tap an instrument square to pick its Pattern, Sound, Effects or edit its Grid.
- Set the vibe up top: BPM, time, key and loop length.
- Jam on the keyboard — it only plays notes in your key.
- Record a lead: hit the red dot and play; notes loop like a looper pedal.
- Share copies a link that contains your whole beat.

Install Beat Lab
- iPhone / iPad: tap the Share button (square with an arrow) then Add to Home Screen.
- Android: in Chrome, tap the ⋮ menu, then Add to Home screen (or Install app).
- Then open it once while online. After that first launch, Beat Lab keeps working with no connection at all.
Randomize everything?
This replaces your current beat with a fresh random one, and clears any recorded lead. You can't undo it.
How to Beat Lab
- Press play. A beat is already looping — the bar above the keyboard shows where you are.
- Tap an instrument square (Drums, Bass, Pads, Lead) to shape it: pick a Pattern, a Sound, an Effect, or open its Grid to edit step by step.
- Set the vibe up top: BPM, time signature, key and loop length. Everything follows the key automatically.
- Jam on the keyboard. It only plays notes in your key (toggle Scale to free it).
- Record a lead: hit the red dot and play — notes snap to the beat and layer each loop, like a looper pedal. Undo takes in the Lead panel.
- Share: copies a link that contains your whole beat.
