What the heck are people actually looking for in an arranger KB....Imo if you cant make great music with what is on the market today there's something wrong with the players abilities NOT the keyboards sounds styles & features.....there is more then adequate gear out there to do anything with at this time.
Improving ones chops should be the not the silly nitpicking of sax sounds, a few features, what's better then what?..
How you play is what's important & what it sounds like..
