If you have a lot of tracks in your Arrange window, the Track Mixer can become unwieldy, forcing you into a lot of scrolling to find the tracks you want. To make track viewing easier, create an empty Folder in the Arrange page, open it and create copies of the Tracks. For example, copy the tracks that the backing vocals are on. Double-clicking this Folder will show just these Tracks in the Track Mixer. You can repeat this for groups of drum tracks, guitars, and so on. You must make sure the Track Mixer’s Link mode is on for this to work.
