摘要： A pickup system for an electrical musical instrument having strings includes two pickup windings to respond to playing of the strings. A third winding is included. A switch connects any of the three windings in electrical series with either of the remaining two windings so that any of three respective pairs of connected windings can be selected. The windings of each of the respective pairs are connected such that interference such as 60-hertz hum is canceled.

摘要： The playback speed of an audio signal is decreased or increased by repeatedly reproducing a preset audio signal domain or removing a domain of the audio signal. A memory stores the audio signal and an audio pitch is calculated from the audio signal readout from the memory. The audio pitch and information relating to power of the audio signal are used to produce a memory address sample set to be used in addressing the memory to reading out the audio signal at a desired playback speed. An address phase signal is fed back from a memory address controller to prevent over running or gaps from being formed in the audio signal reading out.

摘要： A method for shifting the timbre and/or pitch of an input signal samples the input signal at a first rate and stores the samples in a memory buffer. A digital signal processor resamples the stored input signal at a rate that differs from the first rate at which the input note is originally sampled and stores the resampled input signal in a second memory buffer. A pitch shifter shifts the pitch of the input signal by periodically scaling the resampled input signal by a window function to create an output signal. The rate at which the resampled data is replicated by the window function determines the pitch of the output signal.

摘要： A tone generator for an electronic musical instrument analyzes an original waveform signal to store results of analysis thereof into a memory. The results of the analysis read out from the memory is interpolated to generate results of the interpolation in synchronism with each sampling clock. The results of the analysis are corrected to cancel a frequency characteristic to be imparted to the results of the analysis when they are interpolated. The results of the analysis are stored into the memory after having been converted. In another form, a reading numerical value formed of an integer part and a decimal part is generated, in synchronism with a predetermined clock timing. The numerical value is variable at a rate proportional to the pitch of a musical tone to be produced. Residual waveform samples read from the memory based on the integer part are interpolated by the use of the decimal part in synchronism with a predetermined clock timing. Synthesized samples are generated based on the interpolated samples and predicted samples generated from the synthesized samples previously generated, for reproducing musical tones.

摘要： An electronic music system for computer-controlled interactive practicing and learning to play a guitar includes a transducer which is detachably securable to the guitar and generates analog signals representing the playing of the guitar, an interface for converting the analog signals to computer-processable digital signals, and a computer for receiving and processing the digital signals. The system uses a communication protocol which employs time stamping of data to permit use with ordinary guitars but without high speed frequency determination. The computer provides audio and video outputs including staff and guitar fingering representations of notes, chords, scales, compositions, and like musical structures, both to teach the user and suggest music to be played by the user and to illustrate what the user has played. The system is operable in several modes which may be controlled by the user by signals produced at the transducer.

摘要： A detecting device for detecting the positions where strings are operated, and an electronic musical instrument using the detecting device, such as an electronic stringed instrument or an electronic keyboard instrument, wherein each of frets, with which conductive strings are brought into contact, is formed of a two-layer structure of a conductive member and a resistance member provided on the conductive member. Voltage pulses are sequentially applied to either the conductive strings or the conductive members of the frets and a voltage pulse is detected from a conductive member or a string, thus detecting a position in which a string is stopped against the fret.
