New jam

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

One tree, the whole track — every take is the full song length.

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. Publishing confirms it's your own original work, shared under the licence you chose above (terms).
