About ATMOSYNTH

ATMOSYNTH is a collaborative music production and performance platform: a place to create and publish synth patches, play them in your browser, and edit and remix the patches of others. A patch is a small instrument built from modules — oscillators, envelopes, filters, sequencers — wired together and shaped until it sounds like something you want to play, loop and arrange.

Every patch on ATMOSYNTH is playable straight from its page, with the keyboard at the bottom of the screen or a MIDI keyboard you have plugged in. Nothing to install — or, if you would rather, the same patches in your DAW through the plugin. If you like what someone made, open it and make it yours: your version is a new patch in your own account, and it remembers where it came from.

A patch does not have to be made alone. Its creator can invite up to twelve others, and everyone edits the same patch at once from their own browser — every change reaches everyone, the audio plays in sync on every device, and you can see what the others are working on.

Your patches belong to you. ATMOSYNTH is built on the Atmosphere network, which means every patch, module and sample you make is stored in your own account. On this site we show your patches and let people play them, but we do not control or own them. If you take your account elsewhere, your work goes with you.

Browsing, playing and making are open to everyone, with no account and no sign-in: start a patch of your own or edit someone else's, and your browser keeps it for you. You need an Atmosphere account when you want to publish your work or edit a patch together with others — publishing writes to your account, which only you can do.
