The UM-1X and UM-1SX have a switch for selecting the Advanced Driver setting. There are two options:
- ON: This mode requires that you install a Roland driver on your computer for the UM-1S/SX to connect. Using this option you can take advantage of Roland's FPT processing technology which provides for faster MIDI processing speeds.
- OFF: This mode allows the UM-1/SX to use the USB MIDI Driver that is built into your computers operating system, and does not require that a Roland driver be installed. This is useful if you have an OS for which there are no Roland drivers available.
