It could be a good idea to combine different layouts, for example: 6 first rows - guitar layout and last 2 rows is piano layout. Or Right part of the controller is piano layout, left part is guitar layout...
Most probably will require application to setup complex combinations, but could be simple - like choose layout and pick top left point where to start the layout - and layout will be placed only in the box from the point and to the bottom right corner.
