Yourock guitar "feedback"

Hello

I have some regular midi devices using the traditional cable, and others like a Korg PadKontrol and a Yourock guitar which are connected via USB.

I am having trouble getting the Yourock to perform correctly. All my other devices are fine, but the yourock causes a “midi feedback loop” as soon as you play it. The last notes sustain forever til I hit the record tab in Cubase to clear it off. Using my keyboard does not produce this… The notes stop when they should after I play the last one. Any idea?

I have my midi filter set to nothing checked, all 16 number tabs set to grey. This is what seems to work for all my other input devices.
