Hey guys, so I recently just got the Tempest and I was trying to update it to the newest OS, but for some reason, the screen went blank towards the end of the first sysex file. After the file was finished, I turned the Tempest off then on, but the Tempest screen remained black. All the lights remained the same, but whenever I tried hitting any of the pads or turned any knobs, nothing changed. Does anyone know what I accidentally may have done? Thanks in advance!
