So I run an Axe-FX Standard with a Behringer FCB1010 foot controller. Everything has worked great for a long time but lately they are having issues communicating it seems. I first noticed it playing a gig and couldn't switch between presets. The foot controller seems to be working just fine (all of switches are working normally). I've tried turning both units off and on and it doesn't help. I've tried unplugging/replugging the midi cable from the foot controller and nothing happens. But sometimes if I unplug/replug the midi cable from the Axe-Fx unit itself it will start working. Sometimes it will work for a few minutes and sometimes it will be fine for days. Is it possible the midi pins on the Axe-FX unit could be worn out? Any ideas?
