MIDI

MIDI is the universal language that allows electronic music instruments, computers and audio devices to communicate with each other¹. It runs parallel to the audio signal, never touching the sound itself, and only sends commands that devices such as DSP pedals, rack gear, and stage lights respond to instantly². On a guitar rig, MIDI is used for switching effects on and off, calling up presets on MIDI-enabled effects, synchronizing time-based effects, and using MIDI expression pedals on effects³. Many pedals offer MIDI control of their functions, from complete control of every knob on the Pigtronix Echolution 2⁴ to full MIDI integration in pedals like the Darkglass Alpha·Omega Photon⁵. MIDI controllers and modules, such as foot controllers and MIDI-controlled loopers, handle switching and preset changes across a pedalboard⁶⁷.
