From the Sequel 2 Thread. It pays to read the forum!
The bonus loops are included in Sequel, however you must activate the license to be able to access them. If you purchased a boxed copy of Sequel, the activation code will be on your "Essential Product License Information" sheet. If you purchased Sequel electronically you will find the activation code that begins with 0240 on the confirmation email. If you still cannot find the bonus loop activation code then please login to your MySteinberg account and send us a Support Request with a receipt of your Sequel purchase and original Sequel activation code and we can generate you a new activation code for the bonus loops in your account. You can access the bonus loops after activating the license and in Sequel going to the Mediabay>select file browser<Content Libraries><Bonus Loops>. Make sure your Media type is set to Audio Files and to clear your filter to see all 500 loops.
