I think its good for making hip hop and R&b beats, I'm just mad at Roland right now cause of what happened to my keyboard... you cannot sample with it tho, so if sampling sounds is important to you this aint the right piece.... the MC-909 is coming out soon I believe, its a sound module/sampler/sequencer, so you can use the sounds in there as well as sample any sound you want into it- supposed to be pretty inexpensively priced compared to other boxes for what it comes with... but it doesnt come with a keyboard and the pads look real cheap so you'll need an external keyboard if you're into playing keys, or some better pads like the Akai piece to bang out drums.
so you don't think that Roland would be a good machine for makin hiphop/ R&B beats?
