If you have purchased plugins or hardware (like an Apollo interface), you must activate them to unlock their full functionality: : Install the UA Connect desktop app.
If you're using an older UAD device, upgrading to a newer model may unlock additional plugins. Check Universal Audio's website for compatibility information and upgrade options.
Universal Audio uses different systems depending on whether you are using hardware (Apollo/Satellite) or running plugins natively on your computer. UAD Spark Subscription
