newbie question

so i be making ambient type music on garageband with a lot of looping and resampling of my midi tracks. and i dont really rely on a metronome, i often dont have a consistent tempo or time signature. garageband is really clunky to use for the ideas i have and im just sick of it as my standalone daw/mpc/whatever

should i get a sp404mk2? does it fit my style?
