76/88 keys is geared toward PIANO Players who play full mode style....most I would assume require a more "Piano feel" key-bed not a lightweight arranger 61 organ type key-bed.......KORG years ago addressed this with their T1, T2, T3 line of keyboards to give everyone a chance to choose how many & what feel they wanted, obviously that was a dud because they are no longer made.....if you play arranger keyboard the way most do left hand chords/ right hand lead/comp which is most of the market here lies their decision to NOT make a 76/88 anymore.....another reason is now we have midi controller keyboards of all sizes which significantly cut into the keyboard sales and has made NOT making 76/88 arrangers even more of a good idea when you can buy a controller Kb and do what you want. 76 keys is a dying breed.
