Hi ! Unfortunately I have a strange problem with my Roland R8. After trying to load sounds from a ROM card it crashed and the only option a saw was to turn it off and on again. After tht it only shows its Name "(RolandR8)" and "Human feel Rythem" in the display. No other function anymore. No sound from the pads. Is there may a possibilty to reboot it as it seems that the system crashed. I don´t have a manual to look for. PLEASE HELP !
