===Drum and percussion controllers===
[[File:V-drums-2.jpg|thumb|right|alt=A MIDI drum kit|Drum controllers, such as the [[Roland V-Drums]], are often built in the form of an actual drum kit. The unit's sound module is mounted to the left.]]
Keyboards can be used to trigger drum sounds, but are impractical for playing repeated patterns such as rolls, due to the length of key travel. After keyboards, drum pads are the next most significant MIDI performance controllers.<ref name="Manning" />{{rp|319–320|date=November 2012}} Drum controllers may be built into drum machines, may be standalone control surfaces, or may emulate the look and feel of acoustic percussion instruments. MIDI triggers can also be installed into acoustic drum and percussion instruments. The pads built into drum machines are typically too small and fragile to be played with sticks, and are played with fingers.<ref name="Huber" />{{rp|88|date=November 2012}} Dedicated drum pads such as the [[Roland Octapad]] or the [[DrumKAT]] are playable with the hands or with sticks. There are also percussion controllers such as the [[vibraphone]]-style [[MalletKAT]],<ref name="Huber" />{{rp|88–91|date=November 2012}} and [[Marimba Lumina]].<ref>{{cite web |url=http://www.buchla.com/mlumina/description.html |title="Marimba Lumina Described".
