Ciao, I'll reply in english since it's the board's "official" language :-)
Thank you very much for your appreciation, I've enjoyed making this short tune.
About your last question, the Paris Exposition demo-song it's been my first "contact" with this instrument. Since it's a very inspiring, I'm sure I'll use it often in the future. I find it's dramatically flexible, so that's great for a musician!
