I was passing my local "sound Control " music shop in Birmingham England and poppedin to killsome time. I sat with the G70 and played for about 30 minutes. I have already spent over a couple of hours with it previously but that was about 4 months ago . I asked the assistant if the board had had the latest operating system upgrade. They said yes. Iam sorry to say my opinion of the board has not changed. Purely in terms of sound it is teribbly disappointing . Thje shop has not sold even one unit and its really not surprising. I am a yammie fan but again i played the PA1X. I have not had the chance to play the Ketron SD1 so i cant compare . But the Korg is an outstanding instrument sonically. In my view the PA1Xis still the arranger to beat on the market. Will see what the Tyros 2 brings......
