There are 'pro' horn players using arrangers that might need the single finger option..!

There are single finger triggering of loops on WS's... yet they are still labeled as 'pro'...

The problem with definitions, especially those made up by marketing people (I'm afraid, as a salesman and demonstrator of Yamaha's, Ian, you sadly have to be lumped into that group) is that they bear little relationship to reality. They are merely conveniences for their own limited vision (they are marketing people for a reason!) of what a product can do.

But until you can come up with a definition for the NP-V80 that makes it into a piano, but DOESN'T make pretty much all other 76's into pianos as well, you simply haven't got it pinned down yet...

Me, I tend to want to make my own mind up about things. No good can come of abrogating that responsibility to a salesman, for Pete's sake!
