Salim,
I'm sorry it has taken so long for me to reply to you. I usually chat in the arranger discussion forum. I would suggest if you have any questions in the future that you go directly there.
The new X1 oriental HD is a great new keyboard. It has features never found on any middle eastern keyboard before it. I would really like it if you would call or could come in so I could explain all the new features.
Regards,
George
