Tom,
In order to get the speed up function to work you must have a 3.0 chip installed on the hard disk board inside the solton. The only way to know which one you have is by removing the cover of the keyboard and looking under the keyboard bed on the hard disk circuit board. There you will see a chip that will say 2.0 or 3.0. If you do not have the 3.0 one can be provided to you by calling Solton in New York. Ask to speak with John in Service. He has the ability to burn the new chip right here in the US. If you are not comfortable with opening the keyboard yourself, please take it to a keyboard service technician and they will be able to upgrade your keyboard.
