Question 1

How do I play the online synthesizer?

Accepted Answer

Use your computer keyboard: A W S E D F T G Y H U J K map to one octave of piano keys (white and black). Click keys with your mouse on touch devices. The synth starts the moment you press a key.

Question 2

What synth features are included?

Accepted Answer

Two oscillators with mixing and detune, a resonant low-pass filter, a full ADSR amplitude envelope, an LFO for modulation, and master volume. Six built-in presets cover lead, pad, bass, pluck, bell and acid sounds.

Question 3

Can I save my custom synth patches?

Accepted Answer

Yes. Tweak any knobs, then click Save Preset to store the patch in your browser's localStorage. Your saved presets appear in the preset bar and persist across sessions on this device.

Question 4

Does the synth work on mobile?

Accepted Answer

Yes. Tap the on-screen keys with your finger. The Web Audio engine runs natively in iOS Safari and Android Chrome. For best latency, use wired headphones instead of Bluetooth.
