Everyone can record in the Studio and use the Editor to export the recordings as clips.
If you have a subscription plan, you can download a specific number of hours of separated tracks each month. To download more, consider upgrading your plan to one with more hours. (Clips and recordings exported from the Editor do not count toward the monthly hours.)
If you have a free plan, you can download 2 hours of separated tracks in total to test them in your workflow. Add a subscription to your account to download more than the 2 hours.
How are hours calculated? Do unused hours roll over?
