On a general point popular music seems to embody less memory than it use to. That trend is almost the definition of popular. The old complexity of music which encourage memory, has been replace by the relatively simple machine imposed groove. That element of 'pattern, complexity, and Memory' in music has been replace by the rap and the habit of borrowing from old grooves..
Maybe that point is too general. It seems to me devices like mpc's, specifically Maschine, should be freeing your imagination, instead of being defined by any genra of music. Maschine shouldn't just be a machanical way to sample records or assemble beats, the way we did back in the days of disks, it should free your imagination to do what is otherwise incredible. The hardware shouldn't impose any restrictions on your creation of music, it should make the imposible, posible..
I say open the box,
