4. You can now select the Flex Time parameters you want, and Logic will run a scan of the audio to detect the notes in the track. Select the Monophonic option if you are using Flex Time on a vocal track. 

All of the other Flex Time options have different purposes, depending on what type of recorded audio you are working with. Click on the Quick Help button and then hold the cursor over each to learn what they are intended for.

Logic Flex Time Not Working

If you are having problems in Logic with Flex Time not working, you might be dealing with a bug or glitch. The best way to address this issue is to quit Logic and open the app again. Just be sure to save your progress, so you don’t lose any part of your project. 

Sometimes weird bugs occur when you are working with Logic, it could be due to something with your Mac, or it might be completely random. A reset of the app can often get things back to running normally again. 

You also might need to restart your computer if closing Logic doesn’t do the trick. If that doesn’t work, ensure you are running the latest version of the app and make any necessary updates if you are not.  

Logic Pro X Flex Time MIDI

If you want to change the timing of MIDI tracks that you’ve recorded in Logic Pro X, it’s actually a little bit easier than using Flex Time. And since it’s a MIDI track you’ll be editing, you don’t need to use the Flex Time feature. 

To adjust MIDI notes and change their time or pitch, you’ll use the Piano Roll, which can be accessed by double-clicking on the MIDI track in the track window. Select the Piano Roll tab if it doesn’t appear automatically. 

This view will give you a closer look at each note in the MIDI track. You can click and drag a note left or right to lengthen or shorten the timing of it. You can also move the note up or down to change the pitch. 

Making MIDI edits is pretty easy and straightforward, but you want to make sure you like your edits before you make them permanent. Always playback your tracks to ensure you made the proper edits you were trying to make. 

How to Fix Timing in Logic Pro X

The Flex Time feature and Piano Roll editor are both good ways to fix timing in Logic Pro X. These allow you to examine every note in a particular track and make minor adjustments within the track itself. 

I always think that getting a good take is the best way to fix timing issues in Logic Pro X. The closer the take is to being completely on time, the less editing work you’ll need to do to make it perfect. 

Using the metronome or a click track is also essential for recording a track at the proper tempo. You should use one of these any time you are laying down rhythm tracks because it will keep everything on time to build the rest of your project around.
