Guide

The home screen is five slats. The tallest one in the middle is the library; the studio sits beside it.

Inside any tool, the rail on the left switches between them. On a phone that rail moves to the bottom of the screen. Escape or the arrow at the top left goes back to the slats.

The library indexes public-domain packs on the Internet Archive: drum machines, single hits, breaks, vocal shouts, room noise. Roughly nine thousand files to start, and a search widens the index as you type.

• — Press / to jump into the search box.
• — Chips under it narrow to drums, bass, melody, vocals, textures, FX or loops.
• — The disc on a row plays it. The bar at the bottom keeps playing while you scroll.
• — The heart saves a row to Files. The plus drops it into the studio as a new channel.
• — The arrow downloads the original file under a readable name.

The studio is a step sequencer. Each row is a channel, each square is a sixteenth note, and the pattern loops.

Four drum channels are already there and they need no download, so it makes a sound before anything loads.

• — Space starts and stops. So does the disc at the top left.
• — Click a square once for a loud hit, again for a soft one, again for silence.
• — M mutes a channel, S solos it. Click a channel name to open its level, pan and effects below.
• — BPM, swing and pattern length sit in the bar at the top. Eight, sixteen or thirty-two steps.
• — Save writes the beat to a cookie. WAV renders two loops offline and downloads them.

The rack holds thirteen effects the studio does not load by default: two filters and an EQ, echo and room, drive and crush, a compressor, a trance gate, chorus, phaser, a stereo widener and an auto pan.

• — Search or filter by type, then press the disc to hear a drum loop through it.
• — Controls opens the parameters. They move while the demo plays.
• — The plus sends the effect, with your settings, to whichever channel is selected in the studio.
• — On a channel, ON and OFF bypasses an effect without removing it.

Saved samples and saved beats live in cookies on this device. Clearing site data clears them, and another browser will not see them.

Cookies travel with every request, so the drawer is small on purpose. The bar at the top of Files shows how much is left. When it fills, export a backup and delete what you no longer need.

Backup writes a JSON file you can restore later or move to another machine. A beat can also leave as a WAV.

The layout is not a shrunken desktop. The portals stack into a list, the rail becomes a bottom bar, controls are sized for a thumb, and the step lanes scroll sideways under a fixed channel name.

Add it to your home screen and it opens full screen and works offline, apart from streaming new samples.

Only public-domain and CC0 items are indexed. That is the whole reason a row shows a name and no creator: neither licence asks for credit.

No cookie here identifies you. Analytics, where enabled, are anonymous and count page views and a handful of actions. Playing a sample makes your browser talk to the Internet Archive, which sees your IP the way any site you visit does.
