Nuendo 4 and QuNeo midi controler

Hello everybody,
I try to work with x/y pads of McMillens QuNeo in Nuendo to direct my surround sound.
The problem: If I leave (don’t press on) the pad on QuNeo, the position returns to center
and doesn’t stay in the left postion.
It would be very wunderful :slight_smile: to get an answer. Thanks.
