Event Mode

Event Mode is an option that can be set in StepMania.

When this mode is on, you get infinite stages and get to keep playing until you choose to quit and go back to the main menu. The mode is usually used in events and tournaments, hence the name, but many players at home also have used this mode.

If this mode is not on, a "set" will consist of three songs (by default; can be set up to 7) and after playing all these songs, you'll be taken back to the main menu.
