So it does appear to be related to Midi CC assignment..... What CC # was your Drehbank sending ? Did you use D2's Midi Learn or Orion's Link to Next Midi Controller ?
As you can see in the screenshot I posted earlier if your controller is sending CC # 120 or 123, double clicking Orion's stop button will set anything assigned to receive that CC # to Zero.
