From the department of screwball ideas that come to you while lying awake in bed at night, here's my own unnecessary contribution to the treble button layout universe. Taking off on the piano key layout, it's provisionally called the Quasi-Piano Chromatic Button Layout. The notes are the same, bellows in or out, though it offers none of the logical benefits of the established chromatic button layouts. There really isn't much good to say about it -- it's pretty silly -- just something for blockheads like me who are afraid to leave the piano layout behind. Still, there are a few good things about it... it fits a 43-note span into a smaller space, you can jump an octave simply by hopping up or down one row and... it looks kind of cool with those hexagon-y shapes. So, just a goofy idea of dubious utility -- but it would be fun to try.
