A playable browser instrument

Virtual Synthesizer Online

Turn on browser audio, choose a starting preset, and shape a monophonic synth voice with oscillators, filter controls, envelope, glide, and a playable keyboard.

Enable audio once

Use the audio control after the page loads so the browser can start the instrument in response to your gesture.

Shape the voice

Choose a preset, blend three oscillators, adjust filter cutoff and emphasis, and change contour, keyboard tracking, envelope, or glide.

Play and explore

Use the on-screen keys or computer keyboard to test a bass, lead, pad, or percussion starting point, then make the sound your own.

Use the interactive tool

Open the full browser tool, make one small adjustment, and keep the first practice session focused.
