Creating a Section Let's continue with the Metro file that we created in 'Your First Session with Metro'. First, let's create a new Section to work with. Remember, each Metro Section is a chunk of musical time containing up to 99 tracks. Sections are independent of each other, but they can be linked together and superimposed, which we'll explore later in this tutorial in Arranging with Subsections. To create a Section: Choose Sections from the Windows menu, or press Command-Y. The Sections window appears, displaying the name of your Metro document at the top of the window and your Sections in the numbered list. Click Section 2, which is currently labeled 'Empty'. This instructs Metro to make Section 2 the active Section for recording and play-back; this also changes the Section name to 'untitled'. Double-click the name of Section 2 in order to name it. Type in the name 'Vamp' in the name field and press the Return key. Now that you've created a new Section to record in, let's move to the next step in this tutorial, Drum Grid Recording.
