Turn something.

A breakbeat, a bass synth, timed delays, and a glitch engine — synthesized from nothing, right here in the page. No samples. It plays fine on its own. It gets dangerous when you grab the controls.

you can't see sound — this is as close as we'll let you get

You're steering eight parameters with one pointer. The board on the right runs this page with both hands.

Press play. Sound works in every browser; MIDI needs Chrome or Edge.

A mouse moves one knob. You have ten fingers.

Try riding the cutoff and the delay at the same time. You can't — not with a pointer. The Knobster puts the filter in one hand and the feedback in the other, with real pots that hold their position when you let go. This page already speaks its language: plug one in, press play, and every control above maps itself. No setup. No drivers. The knobs on your desk become the knobs on the screen.
