I got 2 of these to add to my setup. lots of fun. doesn't come with power supply and i'm not sure which one i need. If anyone knows FOR SURE, please help. Anyway, I'm not really working on dubstep, but anyone who is should add this to their setup. The ability to play with the LFO separate from the ds is perfect. You can sync it to a ds as well. To avoid being stuck with mono output from that I am using second ds for music and other one as trigger for sync. I'll try to get a video up soon to check out. wish me luck. Again, if you write dubstep, you really should get one of these.
