The Track Titlebar Each track displayed in the Graphic Editor has a corresponding titlebar. A track’s titlebar contains a series of buttons and pop-up menus allowing for a number of operations relevant to that track, including output assignments, Data Type display, Record, Mute, Solo, Loop, the resizing of the track’s vertical display (only when displaying multiple tracks), and the ability to change the display to another track Number. As of version 6.2 the track titlebar also contains a synth/effects popup making it easy to make a soft-synthesizer (Virtual Instrument) or effect assignment. More info on this can be found here. When displaying more than one track at a time, titlebars of any inactivetracks appear differently. You can make a track active by clicking on its titlebaror anywhere within its display area (Shift-click to activate multiple tracks at once).
