DP is not bad either, i personally dislike all of the all in one puzzle your music together sample played whatever player types of random creating progs, my advise learn o propper sequencer first, and then add some toys... (reason is not bad if you combine it and use it's strenght, but standalone??? in my eyes a toy! easy to use, but that's way most electronic music sounds all the f&^ing same!!)
