To playback the current project simply press the play button (visual aid item #33). Playback will begin at whatever position the current project time (visual aid item #32) is set to. Playback of the project will mix all tracks together in real-time resulting in the audio you will hear from your PC speakers or headphones connected to your PC. As playback occurs you'll notice the project time value shows the current position of the project that is playing back. Also, the playback level monitor (visual aid item #17 and #18) allows you to monitor the output level.
