# Add and arrange stems
Source: https://docs.aden.space/docs/help/your-music/version-stems/add-stems

Upload the parts you bounced, place each one on the timeline, and mix them against the track.
## Upload stems [#upload-stems]

1. Open the version's **Stems** tab.
2. Click **Upload stems**, or **Add stem** then **Upload files**. Pick as many files as you like, or drop a whole stem folder on the mixer.
3. Each stem lands at the start of the track, ready to move.

A stem plays from the moment you pick it. Press the ✗ on a lane while it uploads to stop it, with nothing saved.

## Other places stems come from [#other-places-stems-come-from]

* **A comment**: a voice memo or audio file on a comment has **Add as stem**. It lands at the comment's timestamp.
* **Your samples**: **Add stem**, then **From your samples**, searches the libraries your desktop app synced and drops the pick at the playhead.

## Place them [#place-them]

* Drag a stem's block along its lane, or focus it and use the arrow keys. Hold Shift for five second jumps.
* The stem's **…** menu starts it at the playhead or back at the beginning.
* Hover a block to see where it starts, and type an exact start like 1:30.25.
* Click anywhere in a lane to move the playhead there.

## Mix them [#mix-them]

The song sits on top and every lane has the same controls. The speaker mutes; hover it for the volume, and on a stem, left and right. Solo sits by the name. Type in a stem's name to rename it.

## Work on several at once [#work-on-several-at-once]

Hover a lane and its icon turns into a checkbox. Tick stems and a bar at the bottom moves, downloads, shares or deletes them together. **Download all** sits next to **Add stem** once there's more than one stem.

## Make a stem the main audio [#make-a-stem-the-main-audio]

**Make main** in a stem's **…** menu makes it the version's own audio. The old audio stays as a muted stem, so you can swap back. It's how a phone voice note becomes the take that plays.

## Full screen [#full-screen]

The button at the end of the track lane opens the mixer full screen, with a ruler in bars and zoom. Escape leaves it.

## On your phone [#on-your-phone]

The version's Stems tab plays every stem with the song and records new ones. Move a stem with the arrows on its row, or pin it at the playhead.
