Custom volume settings

For each title, no matter if it's Background music or a Sound object, you can separately adjust the volume. This happens in the Timeline.

Timeline_Music3

To get the line, click the wave form of the title. Each click creates a mark that can be moved to adjust the volume. A right-click on such a mark will delete it. The line will be removed when the last mark was deleted.

Background music will be automatically faded-out when a Sound object starts. You don't need to do this manually. You can configure the fade-out volume and duration in the music settings.
