Access Virus B pitch bend issues

[Donethur]

Hi,

I got an Access Virus B, really amazing machine. The only issue I have is that I control it with my Kurzweil k2661 and i use the Super Ribbon Controller. The thing is that when I do a pitch bend using the Ribbon it trends to collapse and all the keys play the same note. I believe this is a kind of bug because of the fast pitch bend the Super Ribbon Controller offers. Maybe the poliphony is affected, but I am just speculating...

It is fixed just changing the patch and if I avoid the Super Ribbon I dont get any issue.

Any theory?

Thanks!!
