My first arranger keyboard was a Tyros 2, and I liked it a lot, except the width. It was very hard to stack on a two keyboard stand, so I changed to a psr 950. When the sx900 came out, I had to have it for the chord looper function. It’s a great feature, now I would never buy an arranger keyboard without it. Total game changer!

I still have a Korg Havian, Korg Micro, and Ketron Audya. I’m not looking to change them,but I could get by just fine without them , even though they all serve unique purposes. The sx900 is my my most versatile tool.
