You guys need to throw your arranger keyboards away and play with some real musicians. I can tell that you will never be happy with an arranger keyboard. After working with drunk, drugged, weed smoking obnoxious musicians ( I'm the Obnoxious type) for 20 years, then, and only then will you appreciate an arranger. Five or ten years does not count. It has to be 20 or 30 years trying to work with baby, temperamental mentality to appreciate an arranger.
