Heresy....its basically just a high powered pc with some special software created by OpenLabs to integrate most PC music software and VST compatible synths, fx and programs all into one workstation with all the configurations and shit hooked up to keyboard and interface for you ready to go out the box.....it might have its "own" arps if your using the daw that it comes with to make beats i guess....but each vst synth usually has their own arps and an editor to create your own arps anyways....
