Hello,
Thanks for bringing this to our attention and sorry for the late response. I am able to reproduce your issue and I have passed it along to the developers.
What algorithms are you using in your demo video? Do you have anything else in your signal path or is it just the H9 in the amp’s FX Loop? I have noticed that the switching noise is much more noticeable when sound is being passed through the H9, perhaps there is something in your signal path that is causing extra noise and making the switching noise louder?
