Delete, reset, and move flex markers in Logic Pro for Mac
In Logic Pro for Mac, when you delete a flex marker, any time changes that occurred in the area around the flex marker are either removed—resetting the audio material to its original position—or reset according to the time-stretching offset of the previous flex marker or region start position and the following flex marker or region end position.
You can delete only those flex markers that were manually added or all flex edits that were carried out on the audio file, which includes audio quantization.
You can also change the position of a flex marker in an audio region without changing the timing of the audio material before or after the flex marker.
In Logic Pro, on a track with Flex Time activated, do one of the following:
Place the pointer over the flex marker, then click the “x” symbol in the region header.
