Mutually exclusive: A + A-half + C, LKL + LKR, RKL + RKR-full + RKR-half, C + LKR can’t be engaged together.

A-half: raises strings 5 & 10 a half step (B→C) (no A-half on standard E9)
RKL: raises string 1 a whole step (F♯→G♯); raises string 2 a half step (D♯→E) (standard E9 RKL lowers string 2 a half step (D♯→D); lowers string 9 a half step (D→C♯))
RKR-half: lowers string 2 a half step (D♯→D) (no RKR-half on standard E9)
RKR-full: lowers string 2 a whole step (D♯→C♯); lowers string 9 a half step (D→C♯) (no RKR-full on standard E9)
No RKR — standard E9's RKR lowers string 4 a half step (E→D♯); lowers string 5 a half step (B→A♯)
