For me...the term "arranger" means to allow the musician to compose and try different instrumentation for a musical idea or song. Since I don't play out...having the flexibility to tweak and experiment with different mixes requires a daw. I would love it if manufacturers would provide 3 sets of stereo outs to give more post mixing options once recorded in the daw. Most arrangers require significant time digging in to tweak the tracks for adequate mixing.

At my age...I no longer have the patience for dredging through menus. Let me have the tracks raw for post production. Just my 2 cents!
