yes features are same

I talking about hardware they use in the unit is from the different hardware vendors,,Lot of different in between 61 or 71/88 keys,,,
Basic truth you can come to know if you compare the price difference between 61/71/88 keys....
if the same hardware why it requires these kind of variations in cost
KORG is very good sound clarity in low and high notes no unit other can compare in the universe
