I hope they are not rumors. Casio has provided some "good enough" "semi pro" arrangers in the past, accompanied with relatively low cost. Some even had a mod wheel.

What they lacked were the 4 variations per style, (thus denying the user of the vast amount of Yamaha Roland and Korg styles on the internet) and also other "pro" features.

They certainly have to be very good and agressive at the price , because offering something along the lines of the S910 and costing as much as an S910 won't get them very far.

Competition is good for the consumer.
