Two split points... one of the best reasons for a 76 while you STILL play primarily in arranger mode. Three zones on a 61 can get a bit cramped.
But despair not, all you 61-ers! there IS a workaround, if your machine can do it... Want two different sounds for the RH without having to press a button? Layer both sounds together, and then either use velocity to cross-switch them (piano on lighter velocities, brass on the hard hits, e.g.) or use an expression pedal to cross-fade them (piano with the pedal UP, brass with the pedal DOWN, e.g.).
Try it... you might like it!
