I have two DDRUM 4SE modules that I purchased in August 2009 and I use AT DDRM Roland pads and cymbals. Warning: to use the hi-hat controller with Roland and the ddrum 4 SE requires a Pintech adapter (https://www.pintechworld.com/shop/scripts/prodView.asp?idproduct=71)

I made two videos in order to show how DDRUM it 10 years ago, was close to the truth as to the imitation of real batteries.
it speaks for itself.
