Product Description 
The Alesis Control Pad USB/MIDI Percussion Pad Controller is a compact live performance instrument and an equally effective studio–based MIDI percussion programming tool. The Control Pad features 8 velocity–sensitive pads with a responsive rubber surface for excellent stick response and expressive performance, as well as 2 trigger inputs for connecting external pads such as the Alesis Drum Pad and Cymbal Pad expansion kits. The 2 foot-switch inputs accommodate open and closed HiHat, as well as a kick drum for authentic, realistic percussion performances. Up to 20 percussion setups can be stored to internal memory. Users can customize pads and 2 external triggers into individual settings for MIDI channels, note numbers and customized velocity sensitivity and curves. The Control Pad operates on USB power, or with an included A/C power adapter.
