Everyone uses an arranger for different reasons, granted I prefer as much music coming out to the audience as possible because as a Singer performing with a FULL BAND is my signature sound & always has been since I went solo 17 years ago after 23 years with a 7 pc dance band....I have no problems soloing lead sounds to cut thru the mix at all because I make it sound that way using all the editing tools I need to do so no problem. I make hundreds of people dance everyday & it ain't gonna happen with a stripped down cocktail piano, Lh bass/drum routine at all.......although when I'm in a small situation I have custom styles just for that purpose.....being the maestro is what "ARRANGING" is all about hence the name Arranger Keyboard.....and again in the end result it all about WHAT IT SOUNDS LIKE plain & simple!
