Hey Jacob,there were some time stretching issues in some styles,endings were the liveguitar was false,or they did't stop when style was stopped after playing the ending,some nice improvements in the launchpad,but now you can program the liveguitars in the styles they have no one on board.And little things random.This is typical Ketron,updates,and there will be more coming.But the SD9 is superb,and the sound is the best.
