The problem is that some lazy developer decided to ignore the matrix difference between the Mini (8x8) and the Key 25 (6x8) and derived the Mini code from the Key 25 code, omitting the functionality (I did look at the Python code). And some idiot supervisor let him do it and some idiot marketing director let them sell it that way.
I call BULLSHOT on Akai and Ableton for this. There is no reason other than sheer laziness, ignorance, or user insensitivity for this decision, and it cripples both units severely...
