Is it probable that when you changed banks you pressed the P footswitch and held it down for too long? That’s the only way the H90 would go back to Bank 1 from any higher Banks. To put it another way, if you go from Bank 16 to the next bank by holding down the B footswitch, all we need to do is tap the P footswitch to load the first Program on that new bank; however, if instead of tapping it we hold it down, that would cause the H90 to go all the way back to Bank 1.
