A toy for making tunes

Draw a squiggle.
Get a banger.

Loop Doodle turns anything you draw into a looping tune. No notes to learn, no theory, no wrong answers. Draw a house, a cat or your signature and hear what it sounds like.

Start doodling
Draw on me Zero wrong notes

Try it right here. Pick a colour, draw on the pad and let go.

Three steps. That is the whole manual.

You are not composing. You are doodling, and the pad does the music part.

  1. 1

    Draw anything

    Drag across the pad. Left to right is time, higher up is a higher note.

  2. 2

    Pick a beat

    Choose the drums that play under your drawing, from sleepy lo-fi to DnB.

  3. 3

    Hit play

    It loops forever. Keep drawing, erasing and swapping sounds while it plays.

Same doodle, different groove.

Pick a drawing, then tap through the beat styles. The lines stay the same. Only the drums and the tempo change.

Beat style

What every button does.

You can ignore all of it and just draw. But if you are curious, here is the whole control panel.

Open source

Free to play. Free to take apart.
