摘要： PROBLEM TO BE SOLVED: To generate a natural musical sound by restoring a lost higher- harmonic component even when a sound-recording sampling frequency is lowered and musical sound waveform data are generated. SOLUTION: Musical sound waveform data corresponding to an address generated by an address generation part 23 among pieces of musical sound waveform data which are sampled at the sound-recording sampling frequency lower than an original sampling frequency and registered in a timbre data memory 25 are read out and interpolated by an interpolation part 26. The interpolated musical sound waveform data are multiplied by a sine wave for frequency (f) a half as high as the sound-recording sampling frequency and then shift in the positive direction by the frequency a half as high as the sound- recording sampling frequency. An HPF 29 cuts a frequency component below a half of the sound-recording sampling frequency and an addition part 31 adds the musical sound waveform data after the cutting and the musical sound waveform data after the interpolation together to approximately restore a frequency component lost in the sampling, thereby generating a more natural musical sound.

摘要： PROBLEM TO BE SOLVED: To simply set up the state of a change in the depth of a vibrato/the speed of the vibrato. SOLUTION: When the depth of a vibrato is changed by operating a rendering operator, vibrato depth DP1 is changed and vibrato depth DP2 is also changed. The frequency of an oscillation signal S from an LFO 6 is controlled by a vibrato speed RA2 obtained by adding a vibrato speed RA1 to a speed change signal RTM obtained by the vibrato depth DP2 by sensitivity RS. The amplitude of the oscillation signal S is controlled by a multiplier 7 based on the vibrato depth DP2 . The amplitude and frequency of the signal S are controlled so that its speed is gradually increased in accordance with increment in the depth of the vibrato and the state of the change is set up in accordance with information generated from a tone specification information generation part 3.

摘要： PURPOSE:To play a music with a colorful quality of tone with a small amount of storage capacity in an automatic playing device. CONSTITUTION:In a rhythm pattern memory, a musical instrument group number IGN and a series of event data EVT which follow prescribed rhythm patterns are stored for every rhythm kind. The IGN represents one group among 8 musical groups. Each musical instrument group includes 8 musical instrument tone colors that are to be used to play one or plural kinds of rhythms and these musical instrument tone colors respectively correspond to 8 sound generating channels of a rhythm sound source section. The EVT includes a channel number CHN and sound generation timing data in a first byte and pitch and volume control data in a second byte. The CHN represents one of the 8 sound generation channels. During a performance, a musical instrument color tone such as cymbals is determined by the IGN and the CHN for every sound generating channel.

摘要： PURPOSE:To properly remove only a transient pulsating noise component of a digital signal function. CONSTITUTION:Variation restriction data are calculated for a last output sample value to find a restriction value, which is compared with a current input sample value; when the input value exceeds restricted variation width, the restriction value is selected, but when not, the input sample value is selected and outputted. Therefore, when the input sample value is a pulsating noise, the restriction value is selected and outputted and the noise component can be removed. The variation restriction data are varied adaptively corresponding to the comparison result to perform adaptive control so that the restriction value follows up sudden variation in the original input digital signal function as fast as possible. Therefore, the response and follow-up performance are improved without being made slow to the original sudden variation of a signal.

摘要： PURPOSE:To power ON and OFF plural electronic musical instruments together at a time and to prevent some of the electronic musical instruments from not being powered ON or OFF forgetfully by providing a controller which the turns ON and OFF the electric power sources of other electronic musical instruments linking with the power-ON/OFF operation of a main electronic musical instrument, CONSTITUTION:On the front panel of the electronic musical instrument. a panel switch 62 including a power switch PSW for turning ON and OFF the electric power source and a linking switch for setting the ON/OFF states of the electric power sources of the electronic musical instruments connected to this electronic musical instrument linking with the ON/OFF operation of the power source of the electronic musical instrument is arranged. When a user operates the power switch of the electronic musical instrument, the ON event of the power switch PSW is detected by the CPU 1 of the electronic musical instrument and the CPU 1 sends a power-ON/OFF signal to the electronic musical instruments through a MIDI interface 4. The following electronic musical instruments which receive the power-ON/OFF signal turn ON or OFF the electric powers.

摘要： PURPOSE:To generate a voice signal containing true subharmonics with simple constitution by shifting the timing of formant generation at the time of musical signal generation by a formant system sound source. CONSTITUTION:The musical sound synthesizer device is equipped with a performance part 11, a timbre specification unit 12, a timbre parameter supply circuit 13, a timing generation part 1 which synthesizes the musical sound signal according to the key code KC outputted by the performance part 11 and the formant center frequency fc, timbre signal K, etc., outputted by the timbre parameter supply circuit 13, a fundamental waveform generation part 2, a window function generation part 3, etc. Then the musical sound signal of a fixed formant is generated by repeatedly generating the formant at the frequency of a musical sound to be generated. A subharmonic generating means which shifts the timing of the operation of the formant generating means at intervals of a specific number of times is provided to shift the timing at the intervals of the specific number of times to generate a subharmonic which is a submultiple of the specific number of times of the frequency of the musical sound signal to be generated.

摘要： PURPOSE:To enable smooth performance over a wide sound range even with a limited number of fingers by generating a sound by moving the fingers of the right hand like keying operation on a keyboard musical instrument. CONSTITUTION:A bending switch 12 detects the bending of the 2nd joint of the thumb to detect operation corresponding to finger turning in the performance of the keyboard musical instrument. When the finger turning is detected, key codes assigned to the respective fingers are shifted up in scale unless the last sound generating finger is the thumb. When the last sound generating finger is the thumb, the key codes assigned to the respective fingers are shifted down in scale.
