I own Korg is35, Technics kn2600, GEM sk76. I have also
tried out Korg i30, Yamaha dgx305, Roland va76, and have tinkered in stores with PA80, Yammies, Roland GW70.
Each of the 3 i own has its virtues, but all have drawbacks. None of them is doing enough for me. I would love to have a 76key, but choices are limited, so i'll settle for 61 if necessary if it is the right one.

I don't care what it costs, and I don't care about speakers, sequencing, song files and full arrangements.
I use only bass/drums/perc of styles except for occasionally the brass tracks in a big band arrangement for dancers..and I just use the kbds for live performance...solo or duo. i never use trax backing, just the styles in the kbd to follow me. i don't want to
tweak sounds, create my own, or program styles or anything else. I just want to pick sounds and styles and store for fast access live. I want great piano, rhodes, jazz organ, vibes, strings, brass, human voices. I want styles that really swing with variety and great bass lines in the jazz, swing, latin, brazilian, blues, funk genres. i don't want to have to go into the screen to do anything --like Yamaha makes you do to transpose--I use transposer a lot live.I want as much contol as possible w/sliders, buttons, etc but care not about drawbars for organ.
i have never tried Roland G70, ketron SD1 or X9, Korg pa1xpro or yamaha 9000pro because they don't have them for demo here. Suggestions?
