I have an issue that just cropped up yesterday on my TI2 keyboard. The notes C3, C#3, D3, D#3, E3, F3, F#3, G3 do not work. I get sound from all the others above and below. I have done numerous resets via Hold Edit Arp while unplugging/plugging, but to no avail. I have tried putting the keyboard to sleep and waking up with Transpose buttons. I tried re-flashing firmware to latest but it said I had the latest and would not continue.
The last thing I was doing before I noticed they weren't working was using it as a MIDI controller to a MOOG Minitaur. Interesting enough, the Minitaur doesn't recognize keys above B2, so I thought that maybe the Moog reprogrammed the keys somehow, which is why I kept trying the factory reset procedure.
Is there another way to completely reset the keyboard to factory? I've backed it up already. I don't know what else to do. It's only a couple years old with very little hours on it.
