The list of drumkits comprises both the kits present at system level and the ones at user level.

The System drumkits are those installed with your package manager or when compiling Hydrogen manually. Their location is determined by the compile-time prefix. On Unix-like operating systems, this is usually /usr/share/hydrogen/data/drumkits, or possibly /usr/local/share/hydrogen/data/drumkits. These kits are available to all users on the system, and you usually have no write access to them.

	Tip
	You can still modify those kids by saving a tweaked version as a user level kit.

The User drumkits are those which you can manage yourself. They are stored in the Hydrogen data directory (usually $HOME/.hydrogen/data/) within the drumkits folder. When you have created a new drumkit via New in the Drumkit option of the Main Menu, you can save it using Save As from the same menu. In addition, you can also Online Import a number of drumkits provided by the dev team of Hydrogen.
