MUSICAL INSTRUMENT SELF-TUNING SYSTEM WITH CALIBRATION LIBRARY

摘要

This invention provides a control system for automatically tuning a stringed instrument utilizing a calibration library (60) to tune the instrument in a plurality of operating conditions without recalibration. When tuning the instrument, processor (50) obtains a calibration function from the memory (60) and utilizes it to generate control signals. The control signals are utilized by actuators (90) to tune the instrument. The operating conditions may include changes in temperature and humidity, different sets of strings made with different materials and gauges, broken strings and the installation of a capo. The calibration can also be provided for instruments of different makes and models, string lengths, body materials and actuator types.
