Follow these steps to scan for presets after installing an expansion pack:

1. Navigate to the Preset Menu by clicking on the name of the preset which is currently loaded. 

2. Locate and click the 'SCAN' button on your instrument.

3. Double-click the '---SCAN---.nka' at the top of the Preset Menu. 

4. After the scan, your Preset Menu will be up to date with all your factory, expansion, and user presets.

**Note: This article applies to every Kontakt instrument except for REV, which does not have a scan feature. There are no additional steps required for REV to read your expansion packs.

Furthermore, scanning is not required for any FX engine expansion packs.
