# 4.1. Mixer layout and stored Profiles

This is one of the advanced features of kmix. If you have a standard layout you like, you can save this layout. A layout stores for each channel four configuration options.

- The volume of the channel

- If the channel is shown

- If the channels slider is split (for stereo channels)

- If the channel are muted.

If you want to save the current layout, just press `Control-1` to save the layout as profile `1`. Likewise you can save profile `2`, `3` and `4` by pressing `Control-2`, `Control-3` or `Control-4`.

You can restore a profile by pressing `1`, `2`, `3` and `4` respectively. If you want to start kmix with a certain layout directly set up, you must pass a command line argument.
