Why did you tell me that! Now I'm gonna be uncomfortable!
I just measured 61 keys on my PSR-3000 and on Juno DS, and 61 keys on PSR are nearly equal to 60 keys on Juno.
But I think that a brain compensates it quite well. Even mini keys usually are not that confusing as you may expect them to be.
Well, i think the mind remembers the the distantie getweeën keys.. don’t think i can blindly move more toen 3 octaves.
