Oranges and tangerines? LOL... that's good
Mind you, without an arranger section, maybe more oranges and potatoes..!
Even if you don't use the style section on the gig, I find it to be invaluable in creating SMF's quickly, that you can further fine tune in the sequencer.
And personally, as rapidly as harmonizer quality has risen recently (with none of it available built-in to arrangers, yet) if I used one of those things, I'd probably be happier with an E60 and a Digitech or TC external unit than the D5 or G70 combo. They just sound SO much better...
