This is a perfect solution for those music producers that are short on space and require something compact that works equally good. Well, you now have a solution with this spectacular 25 key MIDI controller. It's power packed with features and comes with a USB to connect to your pc. Working on my new music has become so easy with this unit since it's just plug and play. There's no lag, nothing at all. The Best Part? every knob and pad is MIDI assignable, how cool is that? This is a worthy buy! 5/5 for me
