I have the most current firmware and software for the Helix pedal. I have noticed that the pedal will randomly freeze up and will not allow me to change patches, use any of the buttons/switches/pedals. I can continue playing, but the only way to get control back is to power off the Helix. Yes, I followed the directions on the Line6 site regarding the proper way to do the firmware upgrade... :) I also reset the pedal to the factory settings and re-done the most current firmware update, same issue.
Your help is appreciated...scott
