Join Dot Bustelo for an in-depth discussion in this video Flexing to change project tempo, part of Logic Production Techniques: Making Beats.
There is another really cool aspect of Flex Audio. I can change Logic's tempo in the transport and have that tempo change automatically applied to all my audio tracks just by flexing them first. Let's listen to a little of this track that has a tempo of 86 BPM. (music playing) Okay, that's enough. I have not provided an exercise file here.
I think it will be more fun for you to open any of your own Logic projects and experience changing that project tempo. Now, if I just change the tempo in the transport, everything will be out of time. Let's bring it up to a much faster tempo, like 120 BPM. You can really hear the vocals will be way off from the beat. I'll start from bar 9. (music playing) Completely out of time. Let's bring that back to 86 BPM and-- (music playing) Vocals are fine. So, to effectively change the tempo, all you have to do is flex all your audio tracks first.
You can flex all the tracks at once by throwing them into a group and selecting Flex on any one of them and it will be applied to all the other tracks. I'll do that quickly now in the mixer by dragging across all the faders of the audio tracks, up to, there is where the audio ends. Now they're highlighted to place them into a group. I'll just click into this pane right above the Fader and select Group 1.
Let's check our group settings, and why don't I give this group a name? I'll call this ALL, since it's our audio tracks. And I want to make sure this Editing parameter is enabled. And let's go back out to the Arrange window. And now all I have to do is select Flex on in individual track and they'll all be placed into that Flex mode, and now the transients will be detected on all my audio files, just like that.
And now, all we have to do is change the tempo in Logic's transport and the track will play back in time, including our vocals, at any tempo. Let's try 120. From where we were listening before, at bar 9. (music playing) Let's really push Logic and try at 130. (music playing) Does anyone else want to hear it at 160? Here we go.
(music playing) Nah, maybe that's too fast. In any event, that's how easy and quick it is to change your project tempo after flexing all your tracks.
