I've just got the FS300 and have set one of the switches to toggle P/B. When I press it, it goes into play mode fine, but when I press it again, it goes back one bank. Eg if i'm in 2:1, press the switch, it goes into play mode for 2:1. Then I press it again and it displays bank 1. I've set Tip as Bk- and experimented with setting P/B for Rng and T+R. The other switch is set for Repeat or Tap Tempo. I've made sure that FS1-3 are not assigned. I've swapped cables. Any other ideas? Anyone else had this problem?
