## Windows

Most of the work you do creating songs in LMMS will be done in the program's windowed GUI. Each type of window has a specific purpose.

The [**Instrument Window**](/user-manual/fr/navigation/instrument-window.md) contains settings for an instrument.

The [**Song Editor**](/user-manual/fr/navigation/song-editor.md) contains all the different sound-generating elements and automation segments in a project file.

The [**Pattern Editor**](/user-manual/fr/navigation/3.8.md) is where repetitive loops, such as drum or basslines, can be created and contained.

The [**Controller Rack**](/user-manual/fr/navigation/controller-rack.md) is where controllers are added and configured. These controllers allow you to make alterations to connected parameters, much like an automation segment would.

Most of the parameters in LMMS can be automated by dragging with Ctrl-drag. There are some more convenient shortcuts that can be used without the hassle of navigating through a right-click menu.

* Double-click a parameter to edit its value
* Middle-mouse click on a parameter to reset its value
* Shift-drag one knob onto another to copy the value of the first knob to the second
* Ctrl-scroll on a knob for more fine scrolling (minute changes, slower scroll)
* Shift-scroll on a knob for more coarse scrolling (larger changes, faster scroll)
