There may be more organ companies, but I’d wager the total number of units shipped is still a tiny fraction of arranger numbers…

Then there are offshoot companies like Medeli, and Casio are still pretty strong in the segment, and while Roland may have left the upper end of the market, they are still busy churning out low end and low-mid end arrangers.

There are a lot of boutique car manufacturers making a handful of cars per year. I doubt Toyota are worried!
