I got my MZ-RH10 last week and it works great. However, I have noticed that the title, track, group alphabet inputs are missing K,L,M and X,Y,Z in both capital and lowercase letters. When you press the cursor button to the left or right, it "feels" them, but they are not visible (you click 3 times from J thru N).. I am not sure if all the international letters below them are included, but would be happy with merely all of the Anglo Saxon ones.
