Yes, I’m aware of the semantic differences of the AMT knob in both cases. You are right, but I kinda liked the posibilities. Suddenly the AMT step event could be used to control the amount of note randomness when picking them out of the pool. But it’s a bit messy yes.
We need more attributes I guess. And a Shift button that allows a hole new range of attributes selected with the Shift-attribute combo key. 
Good news on the rests in the chord pool! You managed to squeeze out a free bit from the note pitch data fields?
