摘要:
A method, computer program product, and system for automatically tuning a stringed instrument. An initial height of a first string of an instrument having a plurality of strings and a floating bridge is determined. The height of the plurality of strings is determined using a bridge sensor. The floating bridge is locked. A frequency of the first string is analyzed. In response to determining the frequency of the first string does not match a predetermined frequency, a tuning peg servo motor to adjust a tuning peg, thereby adjusting a string tension of the first string. The one or more bridge servo motors adjusts a spring tension until the spring tension of the one or more springs equals the string tension of the first string. In response to determining the first string is tuned, the floating bridge is unlocked.

Electronic percussion instruments with enhanced playing areas and methods and systems for generating electrical signals in response to impacts to a playing surface are disclosed. A semi-permeable playing surface covering an acoustic noise reducing cavity of an electronic percussion instrument may receive an impact within a predefined impact region, and an electrical signal may be generated in response by an electromechanical sensor that senses the impact. In many instances, the generated electrical signal may be configured to be equivalent in magnitude to any other electrical signal generated by the electromechanical sensor, in response to any other received impact within the same predefined impact region.

An apparatus for modifying an audio signal has an envelope shape determiner, a filterbank processor, a signal processor, a combiner and an envelope shaper. The envelope shape determiner determines envelope shape coefficients based on the a frequency domain audio signal representing a time domain input audio signal and the filterbank processor generates a plurality of bandpass signals in a subband domain based on the frequency domain audio signal. Further the signal processor modifies a subband domain bandpass signal of the plurality of subband domain bandpass signals based on a predefined modification target. The combiner combines at least a subset of the plurality of subband domain bandpass signals containing the modified subband domain bandpass signal to obtain a time domain audio signal. Further, the envelope shaper is operative to obtain a shaped audio signal.

An electronic stringed instrument 1 includes a string-pressing sensor 44 that detects a state of contact between each of a plurality of frets 23 and each of a plurality of strings 22. A CPU 41 detects that picking of any of the plurality of strings 22, provides a sound generation instruction to a connected sound source 45 to produce musical sound of a pitch determined based on the detected state of contact, detects a vibration pitch of the string 22 of which picking was detected, and corrects the pitch of the musical sound generated by the connected sound source 45 based on the detected vibration pitch.

A guitar pickup assembly which would allow a guitar player to blend the sound of two or more pickups smoothly as the player desires via the use of a foot pedal. The guitar pickup assembly includes a guitar separately providing the output from a first pickup and a second pickup separately to an actuator, such as a foot pedal, wherein movement of the foot pedal from one position to another position alters the ratio of the signal from the first pickup and the second pickup.

An electronic percussion instrument may include a percussion member that generates vibrations when percussed, a vibration resonance member, a vibration damping member, and an electronic sound generation unit. The vibration resonance member may include a hub portion, a plurality of radial portions extending radially from the hub portion, and a plurality of spiral portions. Each of the spiral portions may be disposed between and connects respective two of the radial portions. Each of the radial portions may be connected to a respective adjacent one of the radial portions by one or more of the spiral portions. The vibration damping member, disposed between the percussion member and the vibration resonance member, may propagate the vibrations generated by the percussion member to the vibration resonance member. The electronic sound generation unit, connected to the vibration resonance member, may sense the vibrations through the vibration resonance member and generate an electronic percussion sound.
摘要:
A percussion controller comprises an instrumented striker including devices for obtaining inertial measurements and a wireless transmitter, a sensor-enabled striking surface that receives an impact from the instrumented striker, and a data processing system that receives the inertial measurements and predicts at least one of the force or location of impact of the instrumented striker on the sensor-enabled striking surface before impact actually occurs.
