I can identify 3 ToTl arrangers..

Yamaha Genos
Korg Pa4X
Ketron SD9/90/60

You could also add the Roland EA7 and the Casio MZX-500 to that list
As they are theoretically the top of the line from those brands..
But that wouldnt be fair considering their pricepoints.

So whats your personal opinion on them..
Considering strengths and weaknesses?
Which do you prefer, and why?
Which did you try and didn’t work for you?
