I just received my Analog Four and overall I am very happy with it - except one thing. I realized that the buttons of the mini keyboard differ in height, so they feel different while playing. Most buttons can be pushed down almost in parallel to the housing (as it seems common to all other buttons on the device), but four of the black buttons are built-in distinctively “higher”, namely the C#, F#,G# and A# buttons.
Is this normal?
