How exactly are you trying to use the external input? Like, what are you trying to do with it?

I can assure you that it works, as I've used it to use Atomizer within a Cubase session.

Thank You
 

Thanks for all the help and explanations, a lot is explained in manual but not always clear if hardware issue/Education Issue/RTFM Issue/Other software issue.

RFTM - Something do with strange things called Manuals. ;)
