My X1 was in the top 3....of my favorite arranger keyboards.....and yes..the other two were Roland..

Yamaha and Korg barely made my top 10..

What the X1 lacked for me ..was a stage ready OS...and it basically is the same OS today....Let me explain..I needed a board that I could make changes or alterations on the fly...I also needed an easier all around..get around keyboard..the X1 didn't do it...I used the G1000 and the X1 during the same period..the X1 beat the G1000 with drums and bass..as Ketron still beats most of the other boards...Other features and certain sounds..it does not..

My short lived SD1..was very uncomfortable to use...and in a dark room..forgettaboutit!!!

I certainly could live with Ketron products..as my second choice..and still be "happy"...that I could not say about any other boards today...Thankfully, I don't have to go with my second choice...

I don't know what I would do if I needed a 3rd choice.. ...maybe..go back to accordion..
