    摘要: A method for the algorithmic expressive intonation tuning (EIT) and performance of electronic, computer and MIDI musical works relies on melodic intervals, rather than on chordal harmony, and acts by desirably modifying the pitch of a note slightly (compared to equal temperament tuning), depending on the next melodic note. This dynamic, non static, melodic tuning emulates, and can even possibly augment, aspects of outstanding live human musical performance achieved with regard to pitch subtleties, as it enhances the living sounding, real aspects of the performance of electronic, computer and MIDI music, by sensibly causing a slightly different pitch of particular notes, depending on the size of an interval and on whether an interval is ascending or descending, with the same note subtly having more than one pitch often, depending on melodic context. This method of tuning affecting the notes has a further advantage of not requiring transposition, regardless of how much the music modulates, since it uses melodic intervals. It can treat entire symphonies of more than 100 voices simultaneously as easily as solo works.

    摘要: The invention is a control system for automatically tuning a stringed musical instrument with a capo installed, using an original calibration function or closed-loop tuning system for the instrument without the capo. The control system uses a capo scale factor which scales frequencies measured with the capo installed to what they would have been without a capo. The control system enables a musician to quickly tune an instrument after installing a capo, in a manner unlikely to be noticed by an audience.

    摘要: This invention provides a control system for automatically tuning a stringed musical instrument, utilizing a library of calibration functions to tune the instrument in a plurality of operating conditions without recalibration. The operating conditions can include changes in temperature and humidity, different sets of strings made with different materials and gauges, broken strings and the installation of a capo. Calibrations can also be provided for instruments of different makes and models, string lengths, body materials and actuator types. The control system is adapted for use in a stringed instrument having actuators attached to each string for changing the frequency of the string in response to a control signal. Each calibration function relates the frequency of a string to the actuator position of that string. The invention further provides an automatically tuned stringed instrument using the control system, and a method for tuning a stringed instrument.

    摘要: A method is specified for pitch recognition, in particular for musical instruments which are excited by plucking or striking, in the case of which method the interval between zero crossings of a signal waveform of an audio signal is used as a measure for the period length of the audio signal. Reliable pitch recognition is intended to be possible in a simple manner using such a method. The method is intended to be capable of being implemented with a low level of computation power. To this end, the magnitude of the gradient of the signal waveform is in each case determined in the region of its zero crossings, and the magnitude of the gradient is used as an assessment criterion for the selection of the zero crossings to be evaluated.

    摘要: A CPU measures the interval between the zero-crossing points at the two ends of a waveform element a having, e.g., a positive polarity. Thereafter, the CPU sequentially measures the interval between the zero-crossing points at the two ends of each of waveform elements b, c, and d having the same polarity. Upon detection of the waveform element d which is almost equal in interval to the waveform element a and is located nearest thereto in terms of time, the interval between the start points (zero-crossing points) of the waveform elements a and d is extracted as the pitch period of the input waveform. Subsequently, the above-described series of operations is repeated.

    摘要: In an electronic tuning apparatus used in electronic stringed instruments such as an electronic guitar, an electronic violin, and so on, at least one string is extended along the fingerboard. Prior to picking performance, a present state of the extended string is examined through picking said string. Preferably, a reference pitch data extracted through the string-picking manipulation is stored. During a live picking performance, a performance-pitch data extracted is converted into a data for defining a properly-tuned sound-frequency in accordance with said extended string state. A musical-tone having a corresponding sound frequency is generated based on data for defining said sound frequency.

    摘要: A guitar synthesizer comprises a guitar portion and a synthesizer portion which are electrically connected to each other. The guitar portion includes strings stretched between a nut and a bridge and pickup means for detecting a string vibration for providing a guitar sound signal. The guitar sound signal is applied to the synthesizer portion. The synthesizer portion comprises a voltage controlled variable bandpass filter exhibiting a passband characteristic variable in at least two frequency regions of the guitar sound signal as a function of a control voltage. A frequency/voltage converter provides a control voltage representing the frequency of the output of the filter, to the variable bandpass filter, whereby the passband characteristic thereof is made adaptively and dominantly responsive to the frequency of the fundamental wave component included in the guitar sound signal and the fundamental wave component is extracted with accuracy from the guitar sound signal. The synthesizer portion comprises a fundamental wave signal processing unit responsive to the fundamental wave component for generating a fundamental wave associated signal having the same frequency as that of the fundamental wave component and an envelope signal generator responsive to the guitar sound signal for generating an envelope signal representing the envelope of the guitar sound signal. The fundamental wave associated signal is modulated with the envelope signal for synthesizing.

    摘要: A pitch detecting system is provided for an electric guitar having an existing electromagnetic pick-up for strings. For the purposes of pitch detection, all the signals from the guitar strings are sensed by means of an auxiliary pickup comprising a substantially planar substrate of nonconductive material which is mounted upon the existing pickup, below the strings. A plurality of conductive coils on the substrate are each positioned in alignment with a different pole piece of the existing pick-up. The auxiliary pick-up provides a signal representing the sound of each string to a string separator, which transmits to its output only the signals from the auxiliary pick-up which has the fastest rate of build-up of its input signal. The single output signal from the string separator is provided to a pitch detector. In the pitch detector, a reference point in each cycle of the input signal (i.e. the signal from the string separator) is detected by determining when the input signal crosses in a positive direction through a threshold level corresponding to a predetermined proportion of the envelope of the input signal. The time interval between reference points in successive cycles of the input signal is then provided as an estimate of the period of the input signal when the duration is within a predetermined range of the existing estimate. This predetermined range is defined by two thresholds levels, each of which is a predetermined proportion of the existing period estimate. In a second embodiment, a single pitch detector simultaneously processes a plurality of input signals to provide a separate period estimate for each.
