I'm taking delivery next week of a new DM10 module, so I have no more excuses for putting off my DIY build, but a few questions. I'm planning a reflection plate design, possibly using the drop-in cake pan idea with a RP sandwiched in some foam, but what I'm most unclear about is the electrical aspects of the build. What size piezo works best, or are they all pretty standard? I read on here that some of the DIY builds run a bit hot with the signal from the piezo on the DM10. Would a smaller piezo help in that area? Also, what is the wiring schematic for head and rim piezos for the DM10? I've seen diagrams for Roland-based DIY, but I wasn't sure if Alesis uses the same diagram. Any comments or advice is welcome.
