External Editor for Events Cubase Pro 10?

Cubase Pro 10 is offering me an “Open in WaveLab” option because I have a copy of Elements installed.

However, it also finds an evaluation copy of WaveLab Pro which is unlicensed. So I can’t open WaveLab.

The task I’m trying to perform is to Loudness Normalize an event; this is not a feature in WaveLab Elements but it is in Acoustica Pro.

I thought there was/used to be a Preference for external editors but I can’t find it either in the Preferences pane or in the documentation.

Has something changed regarding external editing or am I just missing something obvious?

Thanks. …edN
