I used it many years ago and it has a wonderful layout that shows which finger goes on which key as you learn your scales. Being able to see your fingering in this way greatly aids learning.
What I’ve found elsewhere is scales in standard music notation. Unfortunately, I can guess the scale by the sound faster than I can read it - so that not going to work
Before I buy it again, do you guys use anything similar that has illustrated fingering shown on the keyboard?
