How To Set The Song Key in Logic Pro

In Logic Pro 9, most Apple Loops will behave a lot better when you first set your project’s song key signature. Doing this makes browsing Apple Loops, or your custom made Apple Loops, a much more musical experience. After setting your song key, Apple Loops will (optionally) be transposed to match the song key when you’re browsing in the Loop Browser.

In the Arrange Window, click on the triangle next to Global Tracks to expand. You can also press G to enable Global Tracks. If Signature is not visible, ctrl-click and add it to the Global Tracks list:

    interesting post. How will setting the songs key signature affect midi? Will only midi-tones included in the scale be included?
    And if yes, what happens to the “wrong ones”, transposed to the closest highest/lowest one? or not played at all?
