This is encouragingly sophisticated, bringing us continually back to the focus on control gesture data as the key source of expressive intent and communication. Unfortunately it also foregrounds the dichotomy of idiomatic musical/instrumental gestures: the huge range of the Continuum causes extremes of the pitch/timbre spectrum to sound [to my string-player's ears] contextually unnatural. If I was a pianist, however, I would be positively tumescent with anticipation of buying one!
