I play now the SD9 several weeks,no problem at all,no freezing since the 1.01 update,i send my findings directly to Ketron and yes my friends,they do answer my mail and ask me also what they can do to improve the SD9 for the next update.It's so much better than the Audya,fast,stereo and pressure,sound,touchscreen is superb(the SD7 screen is good but this screen is much better)
