To reverse the polarity, simply power off the Keystation series controller, ensure
that the pedal is not depressed, and power the unit on.
My Keystation is not reading in my computer. Why not?
Most likely this is not due to the actual Keystation itself and is more likely
something to do with the connection, a conflict with something else in the
computer, or software settings. We recommend following the steps suggested
below to determine the cause:
1.
Try connecting to a different USB port.
2.
Try connecting with an alternate USB cable.
3.
Try connecting to a different computer to determine if the cause is hardware
or computer-related.
If the steps above do not help to determine the cause of your symptoms, then it is
likely a conflict with something else on your computer or a needed adjustment in
your software settings. For further information on how to determine if you have a
conflict or what to do when troubleshooting a class-compliant device, please see
