Let's take a closer look at the different parts of the LMMS screen elements.
The Main Menu Bar provides options dealing with project files, accessing some plugins, and accessing online help.
The left side of the Tool Bar has two rows:
Buttons in the top row deal with the project files - create a new one, open, save, and export.
Buttons in the second row are used to show/hide (toggle) the different windows in the main section of the interface.
The right side of the Tool Bar contains some master controls for the song; such as tempo, time signature, volume, pitch, and a master-output visualization pane.
The Side Bar has six buttons. Clicking on any button toggles a tab on/off. Each tab displays a specific type of resource: Instrument plugins, My projects, My samples, My presets, My home, and My computer. These resources are used to compose a song.
The main part of the interface contains a number of windows, each serving a different purpose. You can show/hide any of these windows using the buttons in the second row of the Tool Bar.
When LMMS is launched, four windows are opened by default:
Song-Editor - this is the main component. Here all the different sound-generating elements come together with automation control and sound clips, and all combined produce a piece of music.
Beat+Bassline Editor - this is the window where repetitive song elements (such as drum beats or basslines) can be created.
FX Mixer - this is the sound mixer, where the volumes of each channel can be separately controlled. It also has a sub-window where special effects can be added or chained together.
Controller Rack - this is where so called "controllers" are added and configured. Controllers allow you to make math-depending alteration on other elements.
