I went to use Melodyne last night and it took me to their website for an update to 5.1.1.003 (I was on 5.1).
New in Version 5.1.1
Change: A workaround has been integrated for ARA compatibility with Mixcraft 8.
Fixed: Lead sheets are now exported correctly via MIDI.
Fixed: In Apple Logic, playback can also now be started reliably from Melodyne.
Fixed: Under macOS, shortcuts using the “cmd” and function keys are now displayed correctly.
