I previously posted this on the Ax-Fx forum because I thought it was a problem with the AF3.
I have a button to simultaneously switch channels in two amp blocks.
At one point, only one amp would switch channels.
I then programmed separate buttons for both amp blocks and that worked.
Only when switching both at the same time, it started switching only one amp block.
Sometimes I had to turn the GT22 off and on again to make it work again.
Now it's the second time that I had to power toggle the GT22 after powering up with the AF3.
Just to be clear, the GT22 is connected with a 7-pin cable and powers on together with the AFG3 when I power up the rack.
