Normally you will install a Roland driver on your computer to use the PC-80, but if there is not a driver available, or if you are connecting to a device that does not allow drivers to be installed (such as an iOS device), you can change the USB Advanced Driver Setting for both the Audio interface and the MIDI interface to "OFF." This will allow the PC-80 to use the built-in USB drivers in the system (such as Core Audio and Core MIDI in OSX).
MIDI
- Simultaneously press the MIDI CH and PGM CHANGE buttons, and hold them down for a few moments. The PC-80’s display will indicate “UTL.”

- Use the VALUE encoder or the [7] key of the keyboard to select “SY7” in the display.
- Press the ENTER button.
