George,
If I understood you correctly, you're able to copy the styles from the SD-1, SD-1+, the XD and the X series Ketron units onto the HD of the MidJay and play them as you would the onboard styles? If so, how do they sound compared to playing the keyboards themselves. Is there some tweaking required as there is when styles are converted between keyboard brands?

Also, on the MidJay, how do you select a particular style? And how do you select a particular voice or program? Many of the buttons on the unit appear to be dedicated to DJ type functions for playback of the various format music files.

Is one able to use a multifunction foot controller for various functions, such as fills, etc. as you can on the Ketron keyboards?

Thanks,
Paul C.
