I'm a pianist but I like the Yamaha arrangers therefore I've got a 3000 with 61 keys. I'd love a 76 key version but that's life.

Nevertheless I don't see that it would cost Yamaha a huge amount to use an NP30 or DGX keybed with PSR 900 electronics; as someone has pointed out in a previous thread the Yamaha CVP "ensemble piano" range are arranger electronics with a piano.

I suppose I have to agree with the "if there was a big enough market they'd make one" theory.

Maybe what we need is a DGX 520 "pro"!
