Some tracks on our site come with stem files (separate recordings for elements like drums, bass, melody). If stems are available, you'll see a "Download Stems" option on the track's download page after purchasing a license. Click that link to get a ZIP file of stems for mixing or editing. Not every track has stems; availability depends on the production.
If you need stems for a licensed track and can't find the option, please contact our support team. This article explains how to download stems when they are offered and what to do if you need stems that aren't listed.
