Learn how to get your audio recordings to groove with software instrument and MIDI tracks or simply tighten them up with this tutorial here at Logic Cafe. The lesson covers aspects of the powerful Flex Time tool to Quantize audio recordings.
This lesson explores a very useful application of the Flex Time tool in demonstrating how to change the groove of a pre-recorded drum pattern in Logic Pro. Although quite specific in its outcome, the lesson can be used to simply put drum or instrument recordings in time.
Note: The audio file used in the lesson is Modern Rock Drums 1, taken from the Apple Loops library shipped with Logic Pro 9. This enables you to mimic the session before trying it out on your own audio files if you so wish.
In the arrange window, click on the audio object you wish to edit in this session.
At the top of the arrange window, click on the Flex icon in order to enable Flex editing on the selected object.
Once Flex Editing has been enabled, click on the drop down menu which has appeared on the same track as your audio object and select the desired Flex mode.
Note: As this lesson uses a drum pattern for its example Rhythmic is selected. If you are editing instrument and chordal recordings Polyphonic usually gives the best results.
Step 4You will now see the Transients Logic Pro has detected in your recording. Double click the black bar at the top of your audio object to open it in the Sample Edit window.
Step 5In the sample edit window, click on any transients you do not wish to use in the quantize of your audio. In this example the drum pattern is playing 1/8th note grooves, therefore the 1/16th note off beat transients are being removed as they appear in the middle of drum hits.
Note: If you wish to add transients select the pencil tool in the Sample Edit window and draw them in by clicking at the desired point of the audio file.
Step 6In the top parameters box in the Inspector on the Arrange page, select your desired Groove from the quantize list. In this example 8C Swing is selected.
Step 7That's it! You will now see that Logic Pro has moved the transients to the selected groove Quantize.
