Abstract

An integrated transducer-processor unit for use with a stringed instrument having one or more strings. When the instrument is played, the unit produces electrical output signals for conversion into musical sounds. A transducer converts mechanical vibrations of each of the strings into corresponding electrical signals, and a processor processes the electrical signals to produce selected analog or digital output signals for conversion into musical sounds. The unit processor is integrated with the transducer into a pickup, for mounting on the instrument in proximity to the strings without modification of the instrument. In addition, a gesture pad-processor system provides an interface for a user to send control signals to a device to control at least one function of the device. A touch pad receives positional and pressure inputs entered by the user making a selected predefined manual gesture for conversion into a control signal by the system processor.
