The drums and cymbals of an electronic drum kit usually do not have sounds on board. They need to be connected to the trigger inputs of an external drum module, which is almost always included in the drum kit. Most drum modules allow you to add extra samples by connecting them to your computer via USB. Here you can find such drum modules. They are very practical if you want to build your own digital drum set with electronic drum kit components for instance, or if you want to upgrade your current sound module. We also offer electronic percussion pads and drum machines.
