I play with tablet (drag) and keyboard, single-tapping with left arrow and only using right arrow in triples/streams (alternating singletaps past a certain bpm).
Left Hand = Keyboard (2016-10-27 changed from middle finger singletap to ring finger singletap, still using index as other finger)
Right Hand = Tablet
