Melodyne 4 buggy in Audition

Does anybody else find Melodyne 4 very buggy in Audition?

The biggest issue I have is frequently when I transfer audio to the plugin, Melodyne will not separate the audio into notes. It’s just one long note that I can’t delete or edit.

I also find navigation extremely frustrating, having to move the cursor and trigger playback inside Audition in order to do so inside the plugin.

I’m using the latest version of Audition (11.1) and Melodyne (4.1), on Mac OS X High Sierra (10.13.4).

I’ve not used Melodyne for a while I much prefer Logic Pro X for MIDI translation at present.
