Hi, I would know if you can find any demo of SD3 triggered with MPS-850 edrum. It would be nice to have great sounds even with a cheap module. I know that the mps has not the trigger for the rimshot, but every piece have two zones. It makes no sense to me to spend three times for a medium-level Roland. It would be ok if you could buy a TD50, but you know, the really small price is an incredible way to produce drums with a thunderbolt audio interface with near-zero latency
