Melody is a modular synth & music studio that runs in your browser
Patch together oscillators, drums, a sampler, effects, an arranger and MIDI into a live node graph — and it makes sound instantly, entirely client-side. Nothing to download, no account, and it's free.
What is Melody?
Melody is a free, in-browser modular music environment. You build sound by wiring together small building blocks — nodes — on a canvas: synthesizers, a sampler, a physically-modelled drum synth, effects, sequencers, an arranger, and controllers like a piano roll or an on-screen keyboard. Signal flows along the wires, so the patch you draw is the instrument you hear.
It runs entirely in the browser using WebAssembly and the Web Audio API — there is no server rendering your audio and no software to install. Open a tab and you're making music.
What can you make with it?
Synths
Wavetable and classic oscillators, filters, envelopes and a full modulation system — patch a voice from scratch.
Drums & beats
A modal (physically-modelled) drum synth, 120+ percussion instruments, and a library of 230+ groove patterns across many traditions.
Sampling & recording
Load audio, record takes, chop and play samples, and transcribe audio to MIDI notes.
Arrange a song
A multitrack arranger and timeline, a piano roll, chord progressions on the circle of fifths, and a step sequencer.
MIDI & SoundFonts
Import .mid, .sf2 and .wav; play with a MIDI keyboard; export your work.
Beyond 12 notes
Microtonal tunings — equal temperaments, just intonation, maqam, raga and gamelan scales — are first-class.
How is Melody different?
Most browser music tools are a single fixed instrument or a loop maker. Melody is a modular graph — 150+ node types you can combine freely — with depth usually found only in installed software: a physics-based drum synth, real microtonal tuning, audio-to-MIDI, and a set of unusual live visual analysers (a spectral landscape, a van-der-Pol radar scope, and a neo-Riemannian Tonnetz that draws your harmony as geometry). And it's free, open, and needs no install.
Who is it for?
Bedroom producers and songwriters who want a real studio without the setup; sound designers and modular-synth fans; music students and teachers exploring harmony, rhythm and tuning; and anyone curious who wants to make a sound in the next thirty seconds.
Common questions
Is Melody really free?
Yes. It's free to use in your browser, with no account required.
Do I need to install anything?
No. Melody runs in a current browser (Chrome, Edge, Firefox or Safari) using WebAssembly and the Web Audio API. There's nothing to download.
Can I use my MIDI keyboard?
Yes — connect a MIDI device and play the synths and instruments live, or map its controls to parameters.
What can I import and export?
Import MIDI (.mid), SoundFonts (.sf2) and audio (.wav);
export your recordings, and save whole projects.
