You know, I have been buying Roland and Yamaha gear for years (first Yammie was a PF15, and then a DX7, my first Roland was the Jx3p), and one thing I have observed is they DO usually follow each other in what they are releasing and when although the when is not always parallel.
It really does not surprise me to see Roland drop the 76 note arranger from their arsenal, if indeed thay have.
Only having 61 note arrangers is HUGELY successful for Yamaha, so why wouldn't Roland stop flogging a dead horse, and adopt a similar strategy..
Who knows they, unlike Yamaha, might be planning to incorporate more arranger like functionality in the Fantom range, a sort of cross-gender pro division/consumer division beastie!!!
Or maybe add arranger functions to a bigger version of the Sonic Cell... if so, then THAT would be one killer keyboard, or module!!!
Argghhh!!! Now I am dreaming LOL!!!!
