Editing MIDI controller (section)

===Specialized real-time controllers===
[[Audio control surface]]s often resemble [[mixing console]]s in appearance, and enable a level of hands-on control for changing parameters such as sound levels and effects applied to individual tracks of a [[multitrack recording]] or channels supporting a live performance.

MIDI footswitches are commonly used to send MIDI program change commands to effects devices but may be combined with a pedalboard for more detailed adjustment of effects units. Pedals are available in the form of on/off switches, either momentary or latching or as [[expression pedal]]s whose position determines the value of a MIDI continuous controller.

[[Drawbars|Drawbar]] controllers are for use with MIDI and virtual organs. Along with a set of drawbars for timbre control, they may provide controls for standard organ effects such as [[Leslie speaker]] speed, vibrato and chorus.<ref>{{cite web |url=http://www.voceinc.com/manuals/Dbman_r3.htm#What |title="Drawbar Manual v. 1.2".
