The 222e Kinesthetic Input Port tracks performer hand position in 3D space via IR rings, outputting XYZ control voltages for live gestural control

The 222e adds spatial gesture sensing to the 200e via battery-powered infrared rings worn on the index fingers. A sensor window on the module defines a cone-shaped performance space (approximately 4 inches to 5 feet). Horizontal position maps to one CV output, vertical to another, and proximity (depth) to a third. Each ring has a button that generates a pulse. The rings are color-coded: red for left, green for right (nautical convention). CVs freeze when hands exit the sensing cone. This enables continuous, hands-free CV control of any module parameter during performance — the 200e’s answer to performance expression without a keyboard.

Examples

Route the proximity CV of the left ring to the 292e velocity input to control amplitude with forward/backward hand movement; use horizontal CV to sweep the 291e filter frequency.

Assessment

Describe the three independent CV outputs generated by one 222e ring and what physical gesture controls each. Explain what happens to the CV output when the performer’s hand moves outside the sensor cone.

“As a performer moves his hand to the right, this voltage will increase from 0 to 10 volts. Similarly, a vertical movement will increase the voltage at the vertical jack. As you move your hand toward the window, the proximity voltage (purple jacks) will increase to ten volts.”
