Gosh that's been a while ! A bit of a topic bump, this... and quite off-topic too. Unless you want to suggest that this staccato/pedaling mix would be easier done on a Janko keyboard ? Wow, some scales and chords ! Surely none of this could be achieved on a normal piano Honestly I don't understand this dogged effort to 'improve' an instrument and notation that have evolved over centuries, and which is played to perfection by countless people all over the world. What is wrong with the default keyboard and notation ? Too difficult ? I think not. Will any half-decent pianist be wanting to learn this keyboard to improve/facilitate their scales ? Probably not. What is the target audience for such a keyboard anyway ? The poor sods who can't learn to play a normal piano ? Or the intellectual zealots who can never leave well enough alone ? There does not seem to be a middle ground. Will it give possibilities for a new type of fascinating music, like a quarter-tone piano can ? Doesn't seem to be so. But as a purely academic exercise I guess this has its value. Whatever turns you on ! I'd rather be playing the piano though.
