Headphone Volume while changing beat

I’m running through a KB amp and have the headphone turned off, but when I go to change the beat or drum kit the screen turns white and tells me the headphone volume is 0 and sends me back to the beat I had running. I have to be quick to change the beat or kit.
I have the latest firmware installed.

Please try downloading and reinstalling firmware 2.0.4 to your SD card and see if that helps.

Will do.

Fixed, but the firmware wasn’t the issue, it was my laptop. I guess my wifi was screwing with the signal causing the screen to glitch.
