It was Panasonic, that owned Technics that desided to go out of the music instrument business.
And of course it is money related, as everything else. more profit, more profit and even more profit.
As soon as there are no more money to gain by produce and sell arranger keyboards, we'll se the fall of the keyboards we love to play ....
It's the nature of business, money to the shareholders is goal no 1.
Btw, do you see how similiar Genos design is compared to Korg?
Yamaha have business interests / ownership in Korg.
Just wait and see, something will happen in not too long ........
