Hi Leezone... J) I didn't really need 76 keys as all my previous boards are all 61 and never felt the need for more. I didn't look at the specs prior to purchase as I primarily was very much in love with the audio styles of this keyboard. Now the more I play/discover the more I'm hooked on this thing. I kept the Tyros4 as it complemented this keyboard really well given its SA2 voices, choir and the free style play styles.. Which gets me out of those odd time signatures. Cheers, Ky.
