simply an acoustic kit that is now actually a "Hybrid" kit–using external triggers that attach to the rim and skin (or batter head) so as to trigger other sounds on top of the natural acoustic sound produced or simply to boost it for performance. The triggers detect hits/ vibrations on the batter head and/or hoop rim and generate an electric signal. The signal is then sent to an electronic module/sampler or via cables and an Audio Interface to MIDI-DAW/drum software on a PC/laptop/Mac–to trigger the selected sounds. Usually, the "acoustic triggered kit" has either commercially available mesh head "skins" (silent), or the drummer keeps her natural skins (using acoustic skins for a Hybrid kit are standard practice) and other muting accessories to reduce the acoustic sounds generated when played. This way, an acoustic (electro/acoustic) or Hybrid triggered drum kit has the feel and sizes of the standard acoustic kit but with the added benefits of an electronic kit's onstage silence, controllable volume (an important factor in small venues) or the added sound library available in 2016-era high-end kits, which includes sounds for large gongs and other instruments that are expensive and hard to transport in their original acoustic form. DrumsAnywhere software uses a single piezoelectric microphone, to trigger eight different drum pads on any flat or irregular surface, such as a table or wooden chair. Hybrid kit Some drummers have a mixture of acoustic drums and cymbals and electronic drum equipment (sensor pads and a "drum brain"). For example, a drummer who finds that their cymbals are too loud in the small venues they play in may use electronic cymbals, but acoustic drums otherwise. On the other end of the spectrum, a drummer who has mostly electronic drums may add a few acoustic drums or cymbals to the kit to add timbral variety or "colour". Motion capture kit Aerodrums is a motion capture system that allows a drummer to perform without a kit physically present. A high speed camera captures the drummer's motions and converts them into electronic signals that can trigger drum samples. Senstroke is a similar system that uses bluetooth technology.

The list ranges from progressive rock (Bill Bruford of King Crimson and Yes) and
