Maybe they'll fix it, but it's been close to three months now, and the only person that I know of to even acknowledge there is a problem with the harmonizer is Dave, the CS guy I talked to. He says he advised "Japan" about it and said they are waiting for chips. I can only guess that since they have to make upgrades by chips that they are trying to incorporate everything into one upgrade. But that's strictly a guess, because they are certainly not telling us anything.
There are plenty of good-sounding keyboards out there.
