It's interesting how the word "workstation" can stir up things When you break it down, they're BOTH workstations, BUT workstations that each operate on a "different" platform.

You got your arranger workstations, and synth workstations. I think the confusion is compairing the two as a whole. Don't compare arranger workstations to synth workstations. Compare the arranger workstation to other arrangers that may fall short of what's considered an arranger workstation. (if that makes sense)

Fran pointed out that synth workstations are trying to copy arranger features.., but my friend--that door swings both ways because you see arrangers trying to copy synth workstation features as well

Both are workstations. One functions with the expected features you'd find on an arranger workstation while the other focuses on the features more often needed and used by the synth gurus. The real truth is most arrangers aren't bought for their voice editing abilities. It's the sounds and styles. It's been like this for years. You got your synth junkies (me being one), and your arranger junkies. We're all junkies..., keyboards are like musical crack for us. They cost a shit load of money, we always want more, and detoxing is a bitch!
