Soundbeam is an interactive MIDI hardware and software system developed by The Soundbeam Project / EMS in which movement within a series of ultrasonic beams is used to control multimedia hardware and software.

Soundbeam uses a combination of ultrasound (sonar) and tangible (foot controller) inputs to generate MIDI messages.

Originally designed by Edward Williams for the production of avant-garde dance music, Soundbeam has been used primarily in the field of special needs education due to the minimal physical movement required for its operation.

[2] Jackson and others performed a "Soundbeam Medley" (listed as "Four Kinds of Rice / Hello / Resolution" in the CD booklet) on the Guy Evans and Peter Hammill The Union Chapel Concert 1997 live album.

[3] Due to the system's ability for expansion with four sensors and eight switches, installations have included DAW synchronization (such as with Reason or Ableton), as well as live video manipulation.
