An online modular synthesizer
A modular synthesizer for generative ambient: modules, cables, chance.
Modular is a free online synthesizer for generative and ambient music that runs right in the browser with nothing to install. It has 22 modules: a drone, a polyphonic voice, an oscillator and a noise source, clocks and dividers, random notes and a scale quantizer, an eight-step sequencer and chords, an LFO and an ADSR envelope, a filter, delay, reverb and chorus, a VCA, a mixer, an attenuverter and a scope. Modules connect with cables just like a real modular system: audio, control voltages and events.
Ready-made presets show how ambient is built: slow drones through a breathing filter, random melodies in a pentatonic scale, raindrops made of noise, glass bells on a dotted delay. A 13-step interactive tutorial builds a first patch from scratch and explains what an LFO is, what cutoff and resonance mean, how delay feedback works and why quantizing keeps notes in key. Every patch can be saved to a shareable link, and the result can be recorded to WAV.
All modules
- Drone — A sustained low tone from a few detuned oscillators
- Voice — A polyphonic voice with envelope and filter that plays notes
- Oscillator — A simple tone generator at a fixed frequency
- Noise — White, pink or brown noise for wind, rain and textures
- Clock — The patch's metronome: fires triggers in time with the BPM
- Divider — Passes every Nth trigger
- Chance — Passes each event with a given probability
- Random Note — Emits a random note in a range on every trigger
- Quantize — Snaps any note to the nearest one in the chosen scale
- Sequencer — Eight steps repeating in a loop
- Chord — Builds a chord on every note with a slight strum
- LFO — A slow wave that modulates knobs on other modules
- ADSR — An envelope: attack, decay, sustain, release from a gate
- Filter — Removes highs, lows, or everything but a band around the cutoff
- Delay — An echo with feedback, tempo-synced or free
- Reverb — Space: from a small room to an endless hall
- Chorus — Widens and thickens the sound, like several players at once
- VCA — An amplifier whose volume is controlled by CV
- Mixer — Sums four audio signals into one, each with its own level
- Attenuverter — Scales and offsets CV, and can flip its sign
- Scope — Shows the waveform or the spectrum of a signal
- Output — The way to the speakers: everything you hear passes through it
