Musical instrument manufacturers are usually located in certain areas, since this lets them share technical knowledge, facilities and supplies. In Japan, there is also a shared component purchase office.

The area where most arrangers are built, in Italy, has a long tradition in accordion manufacturing, and this led to developing organ factories, then synth and arranger companies (not to speak of audio devices and accessories).

Primary parts are usually produced in shared facilities, making plastic and electronic components. Design, final assembly and quality insurance is absolutely separate for each company. This process lets each brand have its own personality, while reducing costs for common facilities.

Pieces produced vary for each company and model, but they are in the middle of the two orders you used as the boundaries.
