摘要:
An electronic musical instrument extracts a pitch from an input waveform signal by a pitch extracting circuit (P1 ∼ P6), and directs a sound source circuit (9) to generate a musical tone at the pitch based on the extracted pitch. The sound source circuit (9) electronically generates musical tones at the pitches according to the performance. The pitch extracting circuit (P1 ∼ P6) obtains a fundamental period of the input waveform signal by detecting the time interval (t1) between these first two zero-cross points after two positive peak points of the input waveform signal are detected, by detecting a time interval (t2) between first two zero-cross points after two negative peak points of the input signal waveform are detected, or by detecting both the time intervals (t1, t2).

A sound source control information generating apparatus, an electronic percussion instrument, and a sound source control information generating method, adapted for preventing generation of an unintended sound caused by a rebound of an object placed on one struck head, are provided. According to the present invention, if a first output value with respect to one struck head is obtained, the one struck head serves as a target struck head, and information is generated for controlling a sound source means such that a sound generation process performed by the sound source means differs according to whether the first output value obtained with respect to the target struck head or a value corresponding to the first output value is greater than a predetermined threshold value.

摘要:
There is disclosed an apparatus for generating a musical tone signal in accordance with an input waveform signal, comprising a sounding commanding means for providing a command to generate a musical tone having a designated frequency, level judging means for judging whether an amplitude level of said input waveform signal is below a predetermined value, continue judging means for judging whether the input signal amplitude level below the predetermined level continues for a predetermined period of time and sounding stop commanding means for stopping sounding when said continue judging means judges that said input signal amplitude level state continues for the predetermined time.

An electronic audio signal processor especially suitable for electrical instruments such as electric guitars is provided including a controlled distortion and tone alteration portion and a reverb portion. The controlled distortion and tone alteration portion in one form comprises in cascade a compression stage which compresses the amplitude level of an inputted audio signal, a mid band pass filter, a distortion amplifier for adding controlled distortion to said signal and a complex filter having a roll-off of increased attenuation with increased frequency range in the lower and upper audio frequency ranges, and a generally flat response in the middle audio frequency range except with a dip followed by a peak in the upper portion of the mid audio frequency range. The reverb circuit includes a synthetic doubler which provides an output cyclicly varying in pitch from its input and a stereo analog shift register reverb device having two summers which combine staggered adjacent output lines from an analog shift register in different combinations. Two output mixers in conjunction with a switch provide reverb alone, doubling alone or reverb with doubling.
