Roland PD8 trigger pad

The Roland PD8 trigger pad is a drum pad controller designed for use with electronic drum kits. It is a single-zone pad that can be used to trigger sounds from drum modules, samplers, and other sound sources. It has been used by many professional drummers, including Travis Barker, Dave Grohl, and Chad Smith.

The PD8 works by sending a signal to the sound source when the pad is struck. This signal can be used to trigger a sound, such as a drum sample or a synthesized sound. The pad can also be used to control parameters such as volume, pitch, and panning. The pad also features a built-in LED that lights up when the pad is struck. This can be used to provide visual feedback to the drummer.
