Lowering key of whole song in Logic Pro X

Hi all,

So I download a MT from LC with 12 audio tracks in it.....I load it in to an empty project in Logic Pro X after first having adjusted global key and tempo to suit the incoming audio tracks. So they came in as WAVs and I imagine Logic does what it does to convert them to Aifs or whatever. Now, the original MT is too high for our church to sing. I want to lower the key of the whole song. This can be down super easy in Prime (which I imagine has its own time / pitch flexing magic). How do I do it - for every track in the song in Logic Pro X and non-destructively???

And/or - is there a way lowering the key in Playback in MainStage, which is where these files are destined to be dropped in as CAFs.

^ that way if changing the key signature doesn't work.

Thanks Mike and Travis. Changing the (global) key signature doesn't work for audio other than apple loops and midi tracks unfortunately. And the pitch shifting solution in the apple discussions above starts to destruct the audio before you have gone a semitone or two either up or down.

Prime must use some sort of fancy algorithm to pitch shift the tracks that we download from LC. What is weird is that you would think that the complexity of Logic and the processing power of a MacBook Pro would do this in a heartbeat compared to an iPad.....

Struck Gold over on one of your other posts Travis!

or you could be smart and do this.

This is exactly what I was after as a fix for playback in MainStage.

One of Clay's other videos answers the question of transposition in Logic:

I am trying to go down 5 semitones on a song so now looking at how I can clean the guitar up a bit. Finding that some presets in NI Guitar Rig are working nicely.

Not sure how one of my posts pulled that but it worked so that's good.
