It has been a thing of the past for a number of years now, set aside a short time with the S950. I love the Korg drums too. And Rolands were good.
But let's be honest, ALL the current arrangers are great! If Yamaha were the only one around, I would have no problem happily playing one for whatever is left of my career.
However, for me and my particular situation and desires, there are several better choices.
I'm going to hate to part with my Korg PA900 because they got a lot of things right with it. Hoping the SD7 will no more things righter! smile
