you guys know the fl studio step sequencer mode?

i was wondering if i could find a controller that has a bunch of buttons, like 4 by 16 (like in the picture) that for each button you push, it could activate and dis activate one of the sounds played in the sequencer, like you press a button on the controller, say the one on the very top, at the most left, it would activate and dis activate the sequencer button in fl studio. but in ableton. is this possible? does anything like this exist that doesn't need to be mapped?
