Abstract
A unique system for the implementation of an electric guitar effect activated by motion is fully integrated into the instrument. User control of the effect is implemented as either button/knob type controls or by solid state accelerometer-gyroscope sensors or both. The preferred embodiment describes an electronic pitch transposing effect similar to a mechanical “Whammy Bar” commonly found on electric guitars. The present invention incorporates user movement of the instrument as sensed by the accelerometer-gyroscope provides real time control of the effect. Other example of effects which could be implemented with the invention include: Wah-Wah, Flange, Phase Shifter, Tremolo or Echo.
Claims16
A guitar effect with motion activation integrated into the instrument comprising:
- a. a processor executing control software;
- b. a gyroscope circuit coupled to the processor, the gyroscope circuit generating angular rate information in response to movement;
- C. a set of discrete controls coupled to the processor, the discrete controls generating control information in response to user actions;
- d. a tone control circuit coupled to the processor, the tone control circuit modifying the audio signal in response to user actions;
- e. a volume control circuit coupled to the processor, the volume control circuit modifying the audio signal in response to user action;
- f, wherein the processor is configured to receive an input audio signal and generate an output audio signal;
- g, wherein the control software is configured receive angular rate information from the gyroscope circuit to control the audio effect;
- and
- h, wherein the control software is configured to generate an audio effect by modification of an input audio signal to generate an output audio signal.
A method of controlling a guitar effect using motion activation integrated into the instrument comprising:
- a. executing control software on a processor;
- b. generating angular rate information by a gyroscope circuit in response to movement;
- C. generating control information by a set of discrete controls in response to user actions;
- d. modifying an audio signal by a tone control circuit in response to user actions;
- e. modifying an audio signal by a volume control circuit in response to user action;
- f. receiving an input audio signal by a processor;
- g. generating an output audio signal by a processor;
- h. controlling an audio effect by control software based on angular rate information received from a gyroscope circuit;
- and
- i. generating an audio effect by modification of an input audio signal by control software to generate an output audio signal.
