Let listeners add to a track
Let people with the link upload versions, stack stems, hear your project files or ask to collaborate.
A share link is read only until you turn one of these on. Each is a pill in the share dialog, and a switch on the link's card afterwards. All are off by default.
Collect new versions
Turn on Anyone can add versions. Anyone with the link who is signed in to Aden can upload a new version from the share page. The upload is credited to their account, so you always know who sent what. They don't need to be on your team.
What they add arrives as a plain new version. It is never marked final or renamed: promoting it is your call.
Collect stems and ideas
Turn on Anyone can add stems. Signed in visitors can drop a hook or a harmony on top of the track, and everyone with the link hears it stacked over the song. Good for "send me your ideas".
Let people hear your project files
Turn on Project files. The share page gets a Project files tab where anyone with the link can press Play and hear a project's arrangement in the browser, without the DAW. Nothing can be edited or downloaded from it.
Hear from people who want in
Turn on Collab interest. Visitors see I'm interested in collaborating, add a line about what they'd bring, and it lands in your team chat with the song attached, so you can reply right there.
They need an Aden account, so you always get a person you can message back. People already on your team don't see the button.
When visitors aren't signed in
They see a sign in link where the option would be, so nothing looks broken.
