There are Arrangers (without the sound editing and sequencer)...and there are Arranger Workstations (with sound editing and sequencer).
Simple, eh?
And no, there is not a huge difference between arranger workstations and workstations...you already implied that by your description of Korg's arranger workstations.
There used to be a big difference...not so today...the line is blurring considerably.
I still think Squeak said it best.
