Paid libraries

Downloads for paid libraries are handled by Pulse – a free downloader app specifically for audio software.

See below for details.

Download our free ROOTS libraries with Native Access. 

Add the serial key (found in your purchase email) to Native Access to download and register the library in one step.

Do not attempt to download via Pulse – the serial key will not be recognised!

Paid Kontakt library download instructions


If you don’t already have Pulse, download it using the link here.

It’s free and available for Mac, Windows and Linux.

Once downloaded, click on the installer to install on to your machine.
Open Pulse and register a user name and password or enter your existing Pulse details.

Please note this is NOT the same as your Westwood Instruments account name and password.
Once logged in, click on “+ Add a Product”.

Copy and paste your serial key (found in your purchase email) and click Redeem.


You will be asked where you would like to save the instrument. Choose a suitable location with enough free space and click download.


Register your new library in Native Access. Use the same license key as your download to register.

You don’t need to do this step for any of the UNTAMED series (Solo Strings, Brass, Winds, Percussion). These libraries are for the FULL version of Kontakt only so they can’t/don’t need to be registered in Native Access.

If you’re unsure how to do this, you can find further details on Native Instrument’s website here:

Enjoy your new instrument and go write some awesome music.

Download FAQs

Wait a minute, not another downloader app!?

Rather than a download manager for every developer you buy software from, Pulse is a universal solution used by multiple audio companies.

It’s great as you can manage the download and updates of many sample libraries and plugins, all from one place. You should end up with less clutter on your hard drive, not more!

Do I need to register your libraries in Native Access?

Yes, all of our libraries need to be registered in Native Access, except for the UNTAMED series libraries (Solo Strings, Brass, Winds, Percussion).

You can only register sample libraries (from any developer) if they are for Kontakt PLAYER. You can not and don’t need to register libraries made for the full/paid version of Kontakt.
