The RD-700SX normally requires that a Roland USB driver be installed on your computer to be able to communicate correctly. If you have an operating system that is not supported, you can set the RD-700SX to use the MIDI driver that is built into your computer's operating system (for instance, Core MIDI on Mac OSX). To do this you must change the USB Driver setting to "Generic."
- Press the EDIT button.
- Use the CURSOR buttons to select "1. SYSTEM," and then press the flashing ENTER button.
- Use the CURSOR buttons to switch menus and select "USB Driver."
- Press INC/DEC buttons to select a "Generic" or "Original."
- Press the "F1 / TONE INFO" button to display "Are you sure?"
- Press the flashing ENTER button to briefly display "Writing..."
- Turn off the power to the RD-700SX, then turn it on again.
