Drum Libraries:

For our drum libraries, product downloads and authorization are tied to your NATIVE INSTRUMENTS account. To download and authorize your software, download NATIVE ACCESS and log in using the account you initially used to register your library. From there, click "INSTALL" next to the library you wish to download and authorize.

If you forgot your password or do not have access to your existing Native Instruments account, visit this link for assistance:
