About Synthio
Synthio is a browser-based synthesizer and piano that runs entirely in-page with the Web Audio API. Open it on any device and play immediately using your keyboard, mouse, touchscreen, or a connected MIDI controller. It offers five sound presets (Synth, Grand Piano, Rhodes, Wurlitzer, Organ), a full ADSR envelope, filter and reverb controls, a pitch-bend wheel, keyboard shortcuts, and a chord-pad mode with common chord shapes. No install, no login, no cost to start. A Pro tier adds all waveforms, sampled instruments, preset save and load, and audio/video recording. Built for piano beginners and students practicing without an instrument, and hobbyists exploring sound design. Hand-reviewed and independently scanned on SaaStore.
