Map a range of (MIDI controller) values to an action

Give this a try. It's not using quite the values you posted earlier; it's using DIV 8 and then reserving the value of 0 to turn the LEDs off, so the first "batch" has one value missing. I don't think it will make any real-world impact on the function of the macro, but @Nige_S will probably be able to improve on this, knowing him...
