There is Scale Notes Mapped mode for KEYS-LOCK functionality. It is useful. However, it doesn’t work for hexatonic scales. The blue note isn’t mapped properly and it’s mapped to the next key in the scale.
For example, if the scale is set to C Major Blues Hexatonic Scale, which is composed of C D Eb E G, and I hit Eb of the keyboard, E is pressed instead, even though Eb is a proper scale note.
It happens to all the hexatonic scales. I believe this is a bug.
