I have had Keystep Pro for just over a month now. All worked well at first and unit was upgraded to the latest firmware first thing out of the box. Recently I turned it on and noticed the touch strip for the Roller/Looper does nothing. I did use Roller/Looper previously many times and it worked as expected, all of sudden it just stopped working. If I press anywhere on the strip nothing happens. I am not sure if its the touch strip its self or something other related to the Lopper function. Any suggestions would be greatly appreciated.
