I cannot see "Extensions" in my Audio menu in Cubase 10 or Nuendo 10 - I cannot use ARA2

If the Extensions entry is missing in your Audio menu, please check your Cubase or Nuendo version.

ARA2 operation is available with Cubase Pro 10.0.30 and Nuendo 10.1 and later versions.

If necessary, please download an update from Steinberg.

Please note:

VocAlign Ultra ARA2 operation requires: Cubase Pro or Cubase Artist or Nuendo 11.0.10 or later. 

VocAlign Project 5 ARA2 operation requires Cubase Pro or Cubase Artist or Nuendo 11.0.40 or later
