Thank you for your purchase!
We really appreciate it and can’t wait for you to start making some new music.
Okay, here's how to start downloadingyour new instrument.
All of our downloads are handled by an app called Pulse.
It’s a fast, easy and reliable download manager, purpose built for sample libraries.
You will need the license key that was emailed to you shortly after purchase.
If you don’t already have Pulse, download it using the link here.
It’s free and available for Mac, Windows and Linux.

Please note this is NOT the same as your Westwood Instruments account name and password.


Copy and paste your license 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.

Did you purchase LOST SYNTH, ALT PIANO, ELECTRIC HOME PIANO or LOST PIANO?
You need to register these libraries in Native Access before you can start using them. Please use the same license key as your download to register.
You do not need to register any of our other libraries in Native Access, only the ones listed above.
If you’re unsure how to do this, you can find further details on Native Instrument’s website here: https://support.native-instruments.com/hc/en-us/articles/115000685889-Setting-Up-a-Third-Party-KONTAKT-Library
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?
Currently the only libraries you need to register in Native Access are LOST SYNTH, ALT PIANO, ELECTRIC HOME PIANO and LOST PIANO.
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.
