Have you tried following these steps:
What is the original tempo of the MIDI region. Where do you get the MIDI region from?
It is designed as a MIDI file in the Melodyne. Exported to the USB. Imported on my computer desktop and inpotert on LogicPro 9. Original thempo was 124 in the Melodyne, but it was much longer in the Logic. That is much lower thempo.
I tried to use expand Audio to Locators function but it does not work for MIDI.
How can I solve this problem?
Is the tempo half that of Logic? e.g. 62bpm?
Anyway... you can do it manually:
Hold down the Option key and drag the right boundary of a region to time-stretch it.
I'd recommend adjusting the length of the region first in the Piano roll or Arrange area and then using the technique above.
Hope that works.
