OK...I've seen about a million posts about this topic but none of them seem to answer any questions...In Garageband, if I make my own music using musical typing, I can alter the tempo of the music, which in turn will slow or speed up the song...meaning it will sound faster or slower...now when I go into Logic Express and import a song from iTunes and try to change the tempo of that song, nothing happens...the tempo will change, for example from 120 BPM's to 150 BPM's and the song will look shorter, but the song sounds exactly the same...it does not sound faster or slower. So what I am wondering is if you can slow down or speed up the sound of the song using an imported file from iTunes in LE 7. Sorry for the length but it is difficult to explain...thanks!

    It is because you are not changing the tempo of the FILE. You are changing the tempo of the internal click within Logic Express, as well as the tempo at which LE will play back MIDI files and Apple loops. This is the tempo at which you will work with a project, such as a song you are recording. In order to alter the tempo of the FILE, which is what you are trying to do, you must double click on the region within Logic, and you will see the waveform get really big in a new window. Within the menus on the top, choose "Factory," and then "Time and Pitch Machine." This will allow you to alter the tempo of your song. Use the fun little animation graphic thing to alter the tempo and even the pitch of the imported iTunes song you are trying to work with.

    Hope that helped.

    yes! this helped me greatly...the only thing is, what format do the files need to be in in order to click on time and pitch machine...becuase I can only do this with certain files...also, how would I go about changing the format of the files???...one more thing, how do I find out the actual BPM of imported songs...is there some kind of outside software that I need to obtain? Thanks a lot for all the help...

    I figured it would


    what format do the files need to be in in order to click
    on time and pitch machine


    Most likely AIFF

    also, how would I go about
    changing the format of the files???


    in iTunes, go to preferences > advanced > importing > under the "import using" tab, choose "aiff encoder" > click "ok" to close this out

    control click on a song and choose "convert selection to AIFF". . . voila, there you go

    ...one more thing,


    that's it?

    how do I find out the actual BPM of imported
    songs...is there some kind of outside software that I
    need to obtain?


    Software can get CLOSE to telling you, but not exactly, because it reads the waveform peaks, and it can be off. I take it you are not a musician, because if you were, you would know how to do this with no software. Get a metronome (www.metronomeonline.com, or the one in logic, because you can increment the BPM by hundredths of thousands of a beat. . . pretty cool) and play your song, run through the tempos until you find one that matches the tempo of the song. May take some trial and error, but this will be more accurate than your software. Most of the time. If you have any more questions, ask. Just know, don't always rely on software to get things right for you. . . you have to have the skill and practice to be able to discern when the software is operating correctly. . . such as beat detecting software.
