		The adaptor module parameter allows you to select either:

		0 - Roland Soundcanvas support (default)
		1 - Midiator MS-124T support (1)
		2 - Midiator MS-124W S/A mode (2)
		3 - MS-124W M/B mode support (3)
		4 - Generic device with multiple input support (4)
		* 0 - Roland Soundcanvas support (default)
		* 1 - Midiator MS-124T support (1)
		* 2 - Midiator MS-124W S/A mode (2)
		* 3 - MS-124W M/B mode support (3)
		* 4 - Generic device with multiple input support (4)

		For the Midiator MS-124W, you must set the physical M-S and A-B
		switches on the Midiator to match the driver mode you select.
