Thank you very much for your excellent advices.

Of course the best way to be sure is to try it personally. My problem is that I'm in a country where a very few instrument models are sold and at a price you REALLY cannot imagine

So I'm telling my sister to bring one with her from France.
I just hope to find a MP6 or MP10 here in Lebanon. It's very close to what I was searching for. A stage piano with some piano feelings added to voices like rhodes and organs which is perfect for my band work.
However I hoped to find something that really focuses on the piano sound and concept more than putting diverse options and extra voices like strings or woodwind which are often unused.
But thank you, you gave me good directives
