Hello To Uncle Dave,
The Sd1 navigation is simular to the PSR9000pro . Select the sound catagory , look in the screen and choose the sound you wish by using the function buttons on the the side of the LCD display. Very much like Yamaha and Technics.
The mystery software for backing up the harddrive will not be over looked by Ketron on the SD1 .
I will still take the convenience of one keyboard with a hard drive vs. having laptop computer ( how much money invested), PSr 9000pro ( $2800.00 or more), mini disk player on stage.
