while any MIDI application is running.
* Do not connect or disconnect the USB cable while the RD-300SX’s
power is on.
* If not using USB, disconnect the USB cable from the RD-300SX.
* If, during the transmission/reception of data, the computer switches to

What is the USB MIDI Driver?
The USB MIDI Driver is a software which passes data between
the RD-300SX and the application (sequencer software, etc.) that
is running on the USB-connected computer.
The USB MIDI Driver sends data from the application to the
RD-300SX, and passes data from the RD-300SX to the
application.
