qwerty keys should allready work on your 'piano roll' load up an instrument like anakig and start hittin keys. should work are you planning in producing?? if so.... i reeeeally think u should get a midi keyboard first... mine has trigger pads on it, channel faders, rotary knobs. so you can perform with it as well. you'll start getting bored w your launchpad and pissed off you dont have some real, velocity sensitive keys in front of you
