FlexVerb is a brand new plug-in included in Native V6.
FlexVerb replaces the old Duende V5 X-Verb.
FlexVerb will work with existing X-Verb iLok licenses.
Duende V5 and Native V6 can be used simultaneously within the same session if you would like to use both.
Duende 5.1.3 was the last version to include X-Verb and is still available for download from Duende Native downloads.
