Thanks for mentioning this. I also noticed the same thing on the FM3 when switching my main preset from the maxoff to the Chiron. Thanks to others for mentioning an eventual workaround. Will try after the holidaysThe fact is that when using other drives than the Klone Chiron, I did not hear this noise, so I think it may be a mistake. I doubt that the manufacturer of a real the Centaur clone overlooked such a shortcoming.
