Danny you are correct in your thinking Newer is not always better......I revise my statement and say that maybe its too long for Ketron to at least UPDATE the SD-1 or X1 with some needed CONSUMER requested improvements that would increase sales....I personally loved the sounds on Ketron Kb's that Ive owned and performed with, BUT I HATE their Navagation OS in a live situation....if this could be improved by listening to real musicians advice who play every day out there then I would take another look & posibly and other purchase.
