Abstract

A real-time controller of devices such as computers, synthesizers, and processors. It consists of a portable ergonomic body housing a configurable pressure sensitive array of sensors. Ideally suited as a MIDI controller, it may be used to control musical sounds, lighting systems, media viewers, or video games in a real-time or performance environment.

Claims

1. A musical instrument controller, comprising:

(a) a body, with a means for attaching to a human operator,

(b) a single array of eighty-four sensors affixed to the body in a position so that it is accessible to both hands of the operator when attached to the operator, said sensors having the capacity of detecting degrees of pressure, and configured so that active sensing areas form a grid, seven sensors wide by twelve sensors long,

(c) a removable flexible cover for the sensors, with graphics printed on the cover, providing a control surface with visual references, that allows finger pressure to pass through to the sensors below,

(d) a processing unit to detect the sensor pressure and translate the sensor pressure into digital control data,

(e) a communication link for carrying the control data from the processing unit to a slave processor or synthesizer,

(f) at least one raised or lowered area per sensor, on or under the cover, to provide a tactile reference for the operator,

(g) said processing unit having the capability to hold in memory various sensor functions and arrangement programs, and a means for the operator to select between the programs.

2. The musical instrument controller of claim 1 wherein said means of attaching to human operator is a shoulder strap.

3. The musical instrument controller of claim 1 further including a means of producing sound within said body.

4. The musical instrument controller of claim 1 wherein said means for carrying said control data is a MIDI cable.

5. The musical instrument controller of claim 1 wherein said means for carrying said control data is a radio transmitter.

6. The musical instrument controller of claim 1 with additional control sensors, potentiometers and/or switches held by the body.

7. The musical instrument controller of claim 1 wherein the single array of force sensors is a multipoint touch screen.
