No, don't be silly, Diki, my friend...ALL keyboards are not "home keyboards"...just the ones with easy play, single finger accompaniments.

A workstation is a "pro" keyboard that can be used at home by an amateur or a pro.

An arranger(with single finger chording and easy play features) is a "home" instrument that can be used at home by amateurs, or on stage by pros.

Both workstations and arrangers are first presented as what, and who, they are designed for initially...then there are exceptions.

The manufacturers stick the word "Pro" on home arrangers to, as you say, extend the market, but anyone should realize that an instrument with single finger easy play chording, began as an instrument for amateurs.

When they remove single finger chording, then I will agree the arranger is being marketed as a "pro" instrument....but not until.
