I've looked for my original email to Roland Tech dept (can't find it) but I'm sure my question to them was:

Does the Roland VA7 use the same single fingered chord recognition as Yamaha & Technics. Their answer was NO. This is correct so long as there is no MD-2 mode.
If there is an MD-2 mode then they gave me false information and lost the sale of a Roland keyboard.

We'll see what they say when I ring them, one things for sure they've not been quite so efficient as one would expected.

Kind regards

Peter
