Why is it so? On other Yamaha keyboards, I have been able to split the right hand section into two parts, playing R1 on the lower section and R2 on the upper section with the style split still on F#2.This means you can play fills etc on another instrument. Easy on the SX, but I thought I used to do it on the 910 and 970. I might be thinking of my KN7000.Cheers Jean Olivia.
