Hey bro! The International House of Prayer in Kansas City does a lot of loops, EDM synths and live stuff of that sort. YOu can check them out and even look for some of their artists on line and ask them some questions about it. Go to IHOP.org,
Just a quick note, does your church have an in-ear monitoring system? If so, a click track will really help with the pre recorded loops and such. It will keep the band in tuned with the loop controller.
