The pads are all custom built, basically alesis realhead pads but with mesh heads instead. They are all dual zone, meaning you can trigger the mesh, or the rim. The mesh is very responsive, feels much more like a real drum head. All the patch cables are included, as well as the frame and mounts. Everything is run through an alesis trigger IO allowing you to modify velocity curve, note, threshold, sensitivity, and more. This set must be plugged into a computer or iOS device that accepts midi. It's a lot of fun to play. Feel free to ask any questions!
