From the web page Melodyne Studio bounced me to:
New in Melodyne 4.2
New functions and improvements
ARA in Logic: Melodyne 4.2 supports ARA integration into Apple’s new Logic Pro X 10.4.2. With ARA, transfers are no longer necessary in Logic, and Melodyne follows all changes made to the audio track.
The transfer path in Cakewalk/Sonar: When using the Melodyne VST3 plug-in in Cakewalk/Sonar, the transfer path is now created automatically within the current project (Cakewalk Projects / <project folder> / Melodyne / Transfers).
Improved interaction: Melodyne 4.2 interacts even better with Studio One and now requires Studio One Version 3.5.6 or later.
Additional keyboard shortcut: You can now assign a keyboard shortcut from the Preferences dialog for the command “Reseparate Notes at Starting-Point Lines” that appears in the context menu in Note Assignment Mode; the shortcut is then also available in edit mode.
