Gilbert, if I could try out a Korg arranger, I would more than likely have one here to compliment the Yamaha.

At one time I was very interested in a Roland arranger, most specifically, the E-80, which I was able to try out.

However, Yamaha managed to improve their organ sounds (especially the Hammond emulations on the S910 and Tyros2/3) so one of the reasons to get the Roland was eliminated...the other issue was the weight of the E-80, a terrific sounding, and well featured arranger otherwise.

Today's TOTL arrangers are all exceptionally gifted...it's now only down to personal tastes and needs.

What Korg are you using...the PA2XPro?
