I usually play in split mode with the General Preset 1 Right 1 piano an octave lower, Right 2 piano in regular octave and Right 3 strings on the Tyros 2. You could set up Right 1 and 2 like this on your 3000.

This is a quick way to change the range of the piano. If I want to switch between one or the other I press both R1 and R2 together making it only one action instead of 2 seperate pokes at the buttons.

This also is a great octave piano sound with both R1 and R2 on. Much better to me than the single voice octave piano's 1 or 2.

Other than piano the other voices don't really need more that 61 notes, IMHO.

Food for thought.
