Hi Ahmad

Thanks for the info and get us informed. I tried out a Roland E40OR a couple of days ago. It had a sort of an octave's worth of keys on the deck to accommodate Arabic tunings. I noted that the Korg PA80 has a system where you can go into an "Arabic" mode and pick keys for lowering the ptich by one-quarter tone. How does the X1 switch between Arabic tuning modes?
