The DM10 from Alesis is a drumming and percussion sound module with 12 inputs for electronic drums and cymbals. It's loaded with 100 preset drum kits (and 100 user assignable kits), and each sound has multiple velocity-sensitive layers depending on how hard the attached drum or cymbal is struck. It can accommodate drum pads with two zones, and both zones can be triggered simultaneously creating a realistic layered composite of a drum sound.
The DM10 has been designed to deliver a realistic drumming experience with its 1047 preset sounds. The built-in sequencer can play accompaniment parts so you can practice and record your chops, and you can also plug in an external CD or MP3 player and jam with your favorite music. The DM10 can also be attached to a computer via its USB port to load more sounds into it and to trigger software instruments like BFD, Toontrack, and Reason.
