An arpeggiator synth sequencer with real-time music-reactive fractal animations — all running live in your browser, powered by Tone.js.
From chord selection to fractal animations — every parameter is live-tweakable without stopping playback.
Choose from Up, Down, Up-Down, Random Walk and more patterns. Set your BPM and step interval in real time.
Fractal spirals, radial line bursts, and ring waves — all react to your music's amplitude and frequency in real time.
Stack Reverb, Delay, Distortion, Chorus, Phaser, AutoWah, Vibrato, Auto Filter, and Bit Crusher — each with a wet knob and bypass toggle.
Major, minor, maj7, m7, dom7, dim7, aug, sus2, sus4 — across all 12 roots. Or type any custom chord, or roll a random one.
Synth, AMSynth, FMSynth, DuoSynth, MonoSynth, MembraneSynth, and MetalSynth — switch instantly without stopping playback.
Hit Warp to instantly randomize your oscillator and detune — Random, Wild, or Subtle — for unexpected sonic adventures.
Toggle the control panel to transparent so you can enjoy the full fractal visuals while still tweaking every parameter.
Fully touch-optimized. Works on iOS and Android browsers — tap to start the audio context, then perform anywhere.
Every effect runs in the Tone.js signal chain. Toggle on/off and dial in wet levels while sound plays.
No downloads, no sign-ups, no plugins — just open and play.
Works on Chrome, Firefox, Safari, and Edge. No install, no account.
Browsers require a user gesture to activate audio. One tap unlocks full sound and kicks off all three visualizers.
Choose from 60+ chord presets or type your own. Set the arpeggio pattern (Up, Down, Random…) and step interval.
Dial in effects, switch synth type, hit Warp for instant surprises. Use See-Through mode to immerse in the visuals.
Everything updates in real time — BPM, chord, effects — without ever stopping playback.
From warm pads to metallic percussion — all switchable mid-performance.
