Hello! We've had our church's Roland for only 14 months and the past month it began automatically setting itself a half key up, which obviously renders it unusable for a team with other instruments. We did a factory reset and also tried the whammy bar but it's still doing it. We use it outdoors since our church is still outdoors but it's southern California so it's not terribly cold. Anyone have this happen with theirs and if so what did you do to address the problem? Mahalo in advance for any assistance!
