I can call a cow a duck. Doesn't make it one! If you wrote 'Organ' on an arranger, would that make it one?

Putting the word 'Workstation' on an arranger doesn't make it one, only in the eyes of potential customers too stupid to research what a REAL WS can do. Were they to take this obvious step, they would see that, while an arranger might have a basic Sequencer, it lacks pretty much ALL the modern WS features like arpeggiation capabilities (many layers deep), audio groove slicing and multitrack audio recording capabilities, deep, deep voice programming and deep flexibility in part assignment and keyboard layout (not to mention MIDI comprehensiveness and all the realtime controllers that grace WS's, nowadays).

Sure, there are a tiny few TOTL arrangers that have a FEW of those features. But not the whole package. And putting the word Workstation on something that is even barebones as an arranger, let alone a WS is marketingspeak, pure and simple. If you think that your arranger IS a WS because it has the word on the panel logo, I've got some land in Florida you might be interested in....
