Hi Nigel,......I have heard that more then once about genos at Namm on the back burner vs their Flagship synths like Montage..Most pro KB players are more interested in synths its always been like that ..
Thats mostly in the US...
The true reason is that Yamaha USA is heavilly involved in the Montage development ( Phil aka Bad Mister ) while Yamaha europe (Martin Herris) is heavilly involved in the Genos. And while they will not openly admit it, there is quite some competition between the two teams.
The true reason why Arrangers are not popular in the US, is Yamaha US not having an interest to sell the Genos and its predecessors at all.
