Sorry guys, MegaDrum has been in development for too long and, I must admit, I used a very outdated algorithm (which I bought from Roland and signed an NDA with them) and it is not performing to everyone's moderate/high expectations, so I recommend you all ask Marctwo for schematics and any new firmware - read on this thread
Again, I'm very sorry I let you all down:(
P.S. Just to be clear - this whole thread is a joke:)
