Nice demo,...that 90's Bossa sounded like a Cha Cha ?
hope to see some live ones in English to explain all the buttons and features of the EA7.

As soon as I find them, I'll post them, Donny.

Thanx Mikem....these studio edited demos never really show off the TRUE sound.... I think most people are scratching their heads saying what is this EA7 all about? And who is Roland targeting?

I have just been able to record the same style endings from E-A7 (from the Sudclavier demo) AND the BK-9 (from Roland's own demo). It's the same Big Band style. The BK-9 sounds much richer! As Sudclavier has obviously recorded via line-in, assuming in good quality, this would mean BK-9 sounds richer. But it could be due to the recording quality. Anyway, the style is exactly the same.
I attach the comparison file!
P.S.: I'll make a new thread about this.

Thanks for posting both demos side-by-sde, Rosetree. To my ears, the BK-9 sounds more realistic and live, and like you said, "richer", but also more detailed. I guess that's what you get when you compare a higher-class keyboard to a lower-class one.

I imagine that the E-A7 probably sounds more like the BK-7. But it's just a guess. Good job!

You're welcome, Donny.

If you were living in Quebec, you'd be able to understand French, too! You should consider moving here, if you like long, cold winters!

Oui Oui je suis en poste à Watertown NY 16 miles de la frontière canadienne quand je suis un gamin dans l'armée ..... ont traversé la frontière vers le Canada à plusieurs reprises, y compris Montréal et Quebec..and oui je aiment hivers froids......

Mais avec ces termes techniques sur le keyboard, c'est une chose différente... J'ai perdu un peu ma compréhense auditive du français. Mais les démos de Sudclavier sont bonne raison pour la réactiver

Votre français est très bon, Donny! Il est bon de savoir que vous étiez à Montréal. En quelle année avez-vous visité?

Sono d'accordo.
