BEEP BOOP
Public beta

Beep Boop. A step sequencer for iPhone and iPad.

Press play. A beat is already there.

A line drawing of the Beep Boop panel, made part by part at the app's own measurements: a step key, the voice dial, a silicone pad, the window, the whole panel on an iPhone, then the same parts on an iPad.
    An exploded view of a touch: the glass, the panel, the engine and the speaker, drawn apart along the one line a touch travels.
    FIG. 8

    From finger to ear

    A touch passes the glass, the panel, the engine and the speaker. It sounds at the next buffer.

    Step key 5 pulled apart along the line a press travels: 1 the foot, 2 the body with its moulded ridge, 3 the lamp's lip, 4 its glass, 5 its light. The layers close into one key; a finger presses it, the body travels 1.5 points onto the foot and the lamp lights.
    DETAIL A

    Step key, apart

    A foot, a body and a lamp. Pressed, it sounds at the next buffer: counted in samples, never timed.

    DETAIL B

    Your figure

    A producer has a figure: a someone made of dots, grown from one number. Turn BODY for another body. Turn FACE for another face.

    It breathes, blinks and looks about, each on a clock of its own. Drag a knob up for another and down for the one before, or use the arrow keys. A knob keeps the last eight.

    Nothing made on this page is kept or sent. In the app you make your figure when you choose your producer name, and it stays yours.
