Electronic devices that connect to other sound-generating devices on which the sound controller sends signals as to pitch, modulation, attack, decay, or other event parameters designated by the sound controller itself, or in combination with the device triggered. This is usually accomplished through MIDI, but control voltage may also be implemented. Though sound controllers are most often modelled on keyboards, they may appear in any form, resembling guitars, wind instruments, or any form that allows interface with a remote sound generator or synthesizer.
