Solutions

Reinitializing the Komplete Kontrol / Maschine Database

In this example, we reinitialize the Maschine database but this procedure is the same with Komplete Kontrol. Please choose your operating system below:

macOS:

Close Maschine and all other music applications.
Navigate to the following folder:
Macintosh HD > Users > *Your User Name* > Library > Application Support > Native Instruments > Maschine 2 / 3
Note: The User Library is a hidden folder on macOS
.
Delete the "komplete.db3" file by right-clicking it and choosing Move to Trash.
Also, delete the Favorites database file that is used by the Komplete Kontrol and Maschine software.
Note: We recommend saving a backup copy of the Favorites database file before deleting it.
In the macOS Finder, navigate to the following folder:
Macintosh HD > Users > *Your User Name* > Library > Application Support > Native Instruments > Shared
Note: The User Library is a hidden folder on macOS.
Delete the "favorites.db3" file by right-clicking it and choosing Move to Trash.
Relaunch the Maschine software and wait for the database to be rebuilt.
Once completed, the presets will be properly displayed in the browser.
