I agree that a great analogue instrument is still greater, but here, given an electric predicate, this works with what keyboardists already can do, and makes it not just a percussion instrument (piano, harpsichord), or a timed note (synth), or a timed note with initial attack control (tracker action pipe organ). In other words pactically the same interface provides much more control of more variables much more easily. Whether great playing, music making and improvising can and does ensue is another issue, but I hope so.
