Hi Leezone, I am not a keyboard player, a percussionist and singer by trade. As an example with the software varranger an sd2 does exactly what an sd5 does. In terms of styles its all the same. From what I was told by someone working for ketron, the sd1000 or midjay will be that instrument. An improved machine, and I would hopefully imagine that one will be able to play the midjay styles through an sd1000 with the proper software. The only thing is you'll have to have a separate controller as the keyboard. the new machine will be closer to the audya, but no keyboard for now.
