I fully agree. This is one aspect of the common keyboard layout that makes me sad: you have to learn many different patterns for every key. With this you only need to learn functional patterns (major, minor, etc.) and suddenly you know them for all keys. Other layouts have been attempted (see the janko layout), but they never caught on. I wonder if the mobility of accordions is one reason they've been able to have more variation.

How does the ableton push solve this problem? Looking at a video it almost felt like they were switching modes for a scale (almost like a harp does with its pedals). I'm probably off here, but I couldn't quickly find docs on how it worked.
