I remember a few months ago starting a topic on the definition of an arranger and some people felt it was a frivolous topic.

With respect to arranger v. ”workstation”, we also have to look at the difference between having a “workstation” feature and the complexity of that feature.

Most people erroneously think that the complexity of a feature determines whether the keyboard is a “workstation”.

Two of the most recognized features of a “workstation” are a sequencer recorder and sound editing. Once a keyboard has those features, they can legitimately be called a “workstation”. Regardless of the complexity those features exist and whether people use them.

Remember, as discussed here, the editing features on an “arranger workstation” it was felt that arranger players can not use them.
