Turn on Sync samples for the audio
Sample audio stays on each Mac until Sync samples is on inSettings → Library; tags, favorites and collections sync without it. Switch it on on the Mac that holds the samples.

The full list: iCloud.
Good to know
- The iPhone never gets the full project. It plays the bounce preview that Save Version makes on the Mac, so a project with no saved version cannot play there.
- The iPhone plays a small copy of each sample, which exists only once Sync samples is on.
- The iPhone cannot delete a project or make a new sample collection. Do both on the Mac.
- A full iCloud plan stops uploads. The status line under the switch says so.
