I had a DM5 pro kit, switched out the DM5 for a DM10. Also added 2 additional crash's, one with choke. if you don't plug in a dual-zone cymbal into the DM10 "Crash" input, you may get an error when you turn on the controller - but you can just hit cancel and everything works fine. When I finally plugged in the the crash with choke into that port, the error no longer shows up at startup. I also added a 10" dual zone pad for the snare, and moved the 8" dual zone to the first tom position to use as a cowbell or tambourine on the rim.
