It is amazing that this statement gets challenged )but is most likely the case) but people seem to want to accept that Yamaha sells the most arrangers.

Between Korg, Roland and Yamaha, we can probably agree that Yamaha has the most brand exposure for arrangers second to Casio.
Because Yamaha has a low-end arranger $100 - $400 in mainstream stores, and also arrangers that are in music stores, they do have a good showing.
That is at least in the U.S.

And remember, other than price and willingness to pay, there is no substantial difference between a TOTL Yamaha arranger customer and a entry level Yamaha arranger customer.
They both want the same thing, --- a glorified Karaoke machine—that is if you believe the users of Yamaha arrangers are well represented here on SZ.


Korg, Ketron and in some respects Roland, have a different type of arranger market – the people who want to do something with their arranger---. And, they also get the best value for their money )although that is very subjective).

But to depend on The dealers
To tell you which arranger is popular among consumers, is risky. Any dealer who wants to stay in business wants to sell the keyboard that brings them the most profit. If Roland has a lot of restrictions on dealers for getting and selling arrangers, but Yamaha is more generous, to the dealer, I wonder who the dealer is going to more likely promote?
