Visual Amplification

A collaboration with Korg and the band  OK Go to develop a series of instruments for the song ‘Another Set of Issues’.

Bassline Loop
The circuitry of KORGs MS-20 mini has been hacked and rewired to play only the 4 notes of the repeating bassline to the song, ‘Another Set of Issues’. Simply rotate the handle to trigger contact between the circuit and the oversized keys that play the corresponding notes. The rotating action required to play the instrument is an intentionally exaggerated gestural interpretation of the notion of ‘looping’ used in electronic music.

Component Specification
• MS-20 Mini circuit board
• 122 Vacuum formed keys
• 122 screws
• 8 metres of wire
• 9 metres of timber
• Laser Cut Clear acrylic

Chorus Contort
The faces and bodies of the band members are magnified and distorted as the chorus of the song, ‘Another Set of Issues’ is played on KORGs MS-20 mini. The 6 notes to play the chorus sequence are programmed as triggers that rotate 6 stepper motors that are attached to large fresnel lenses within the frame.

Component Specification
• 1 MS-20 Mini
• 6 Arduino’s
• 6 Stepper motors
• 6 Stepper shields
• 6 Fresnel lenses
• 10 meters of timber
