New jam

The grid below — tempo, time signature, key, licence — freezes the moment your first take lands. Bar count can only grow. Everything else is up to whoever forks you.

Your first take — optional, you can add it from the jam page later

Create the jam empty to set the grid first and record against it, or attach your first recording now — it becomes the root everyone builds on.

What are you adding?Instrument — your words, not a listAudio file

Your recording stays its own stem, mixed live over whatever comes after it — that's what lets takes be re-layered and branches moved later. Caps: 50 MB lossy / 250 MB lossless, 10 minutes.
