Suddenly 7 keys stop sounding on my KeyLab 61 mkii. They are all spread along the 5 octaves, some whites and some black keys, so no pattern I can tell. The pitch wheel is acting as a volume. I have never created any kind of user presets or something that could have switched to. I opened the Midi Control Center, and I can see the green down arrow at the top left when I press any working key. When I press any of the faulty ones, arrow wont light up unless I put lot of pressure on it, but still no sound. So, I thought of resetting to factory settings...but I can't!! I read that I have to press both Oct+ and Oct- while powering on, but I don't get the message to reset on the lcd display!
Any ideas?
