I have the arabic/turkish oriental kit in the Genesys and......the WK2Iranian styles converted from the WK2Iranian board. As for the scale tuning box, I would think the AS1 will work with the keyboard. I will try it tomorrow at work.
As for the Piano sounds, the new Grand Piano is taken from the ProMega 3 keyboard and so is the Rhodes and Wurlitzer pianos.
A 61 note keyboard without speakers is rumored for early 2003 arrival.
