Open the project that you want to mix down. When you open Logic, the project will load automatically if it was the last project you had open. If it does not load, select "File" followed by "Open" from the menu bar, and then select the project using the navigation window.
Click "Window" followed by "Mixer" on your menu bar. A new window will appear, featuring a series of channel strips (columns). Each channel strip represents one of your tracks. For instance, the first strip may correspond to guitars, while the second corresponds to drums and the third corresponds to vocals.
Click the "Play" button at the bottom of your "Arrange" window (the main project window) to hear how your mix currently sounds. The "Play" button looks like a sideways triangle.
Adjust the channel strip settings on your "Mixer" window as the mix plays. For example, if the guitar sounds faint, you can increase the volume by raising the "Volume" slider on the guitar channel strip. You can also adjust the panning (left, right or center placement) for each channel strip by dragging the circular panning knob clockwise or counter-clockwise. Use the "Inserts" tabs on each strip to add last-minute effects.
Adjust your main mix settings. The far right channel strip (or the second to the last, depending on your configuration) should read "Output 1-2." This channel strip corresponds to the entire mix. Use the "Volume" slider to raise or reduce the main volume (you should reduce it if the vertical peak meter turns red during playback), and use the "Inserts" tabs to add effects to your main mix.
Click the "EQ" box at the top of your "Output 1-2" channel strip to open your main Channel EQ grid. Use this grid to adjust your frequencies and ensure that you have the perfect mix before finalizing. For example, if your mix has only faint bass sounds, raise the bass (low) frequencies on your grid. If bass dominates the mix, try lowering the bass frequencies or raising the treble (high) frequencies.
Click "File" followed by "Bounce on your menu bar. After you have made all of the necessary adjustments and put the finishing touches on your audio project, you can condense it into a self-contained file. "Bouncing" refers to exporting the project as audio.
Enter a name for your song or audio project in the "Save As" box at the top of your "Bounce" dialog box. Directly below, choose the location on your hard drive where you wish to save the exported file. Select your desired "Start" and "End" time in the appropriate boxes. Choose your destination audio format, and then choose any custom settings from the provided options. Click "Bounce."
