Normally you will install a Roland driver on your computer to use the A-49 keyboard, 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 Driver Setting to "Generic." This will allow the A-49 to use the built-in USB driver in the computer (such as Core MIDI) instead of requiring a Roland driver to be installed. This mode is also called "Class Compliant."
Beat me to it - you replied as I was editing my post above for the second time
