Never say never, Donny! If we can't GROW the arranger market, all it can do is shrink. The sooner the open arranger reaches fruition, the better! Nobody seems to be doing anything with a TOTL arranger that would attract an under 30 year old away from a WS (or even an under 40, maybe!), and none of us are getting any younger!
Either the arranger goes for the younger crowd, or things end up like 'home organs', super-expensive niche products for ailing geriatrics or the tiny few aficionados.
Hmmmmm ? seems to me the arranger situation at this time is just a replacement for the HOME ORGAN (Lowery accmp)market of the 60's/70's/80's as it is now less the Wood

... I've been in this game way before arrangers were introduced and survived no problem on stage with just programing backing tracks & playing on top for many years....sooo if the eventual demise of the arranger is evident in our lifetime I say bring it On......styles ...backing tracks who cares I know I can play and make good music either way.........with the repetitious sound of arranger styles I sometimes think of returning to they way it used to be where you could program tracks, and kool basslines, etc.... The Motif, & Kronos, have enough tools to really make this a very good alternative.
