To be honest I don't have much to write here because if you built your MegaDrum without making mistakes, like short circuits, breaks, incorrectly placed parts, loose cables/connections, it is plug-n-play. All you need to do is to put everything into a nice enclosure, connect your pads and a HiHat pedal, configure it and start drumming!

Yet, if you encounter any problems I recommend you read FAQ and if your problem is not resolved, ask for help in the MegaDrum Forum.
