No, the switching is done by the headphone jack. However if you replace the headphone jack itself ou can install one that makes them both on at the same time but then you couldn't switch the speakers off. Or you can wire a switch into the circuit to do it.

This device operates internally at 12VDC. It can run on D-Cell batteries. It uses a transformer-based power pack to convert A/C to DC for the unit. What possible benefit do you see in converting this (if you even could) to a 3-wire grounded system? There most likely is already a fuse incorporated into the PCB internal to the power pack. You cannot wire A/C directly to the device as it is not internally capable of using the voltage. Any ground that you placed on the device would only be effective to the power pack and would not continue on to the device itself. It seems like a waster of time and effort.

i found this for you
SMF Converter is software that converts commercially available Standard MIDI file (SMF) data to a format that is supported by CASIO electronic musical instruments, and then transfers the converted data to the instrument. After data is transferred, it can be used with the lesson function for lesson play. For details about using converted data, see the user documentation that comes with each instrument. http://music.casio.com/e/smf click the blue download button near bottom of page.---- not the four other links.
