I haven't used my PX-5S in over a year and am trying to relearn it. One thing I don't remember is what's happening now. When I press the Bank button on the top right, it flashes blue for a second or so, but even if I hold it down, I can't switch banks. Except one time I noticed the blue light stayed lit, I switched banks -- and now I'm stuck in that bank. I presume this is a malfunction? Since I have a gig in a couple of days, I can't bring it in for repairs. Does anyone know a fix or workaround? Any suggestions would be MOST appreciated! unklebry
