Abstract: A digital wavetable audio synthesizer is described. The synthesizer can generate up to 32 high-quality audio digital signals or voices, including delay-based effects, at either a 44.1 KHz sample rate or at sample rates compatible with a prior art wavetable synthesizer. The synthesizer includes an address generator which has several modes of addressing wavetable data. The address generator's addressing rate controls the pitch of the synthesizer's output signal. The synthesizer performs a 10-bit interpolation, using the wavetable data addressed by the address generator, to interpolate additional data samples. When the address generator loops through a block of data, the signal path interpolates between the data at the end and start addresses of the block of data to prevent discontinuities in the generated signal. A synthesizer volume generator, which has several modes of controlling the volume, adds envelope, right offset, left offset, and effects volume to the data.

Abstract: An electric stringed instrument having an integral accompaniment system is proposed. The vibrations of the strings on the electric stringed instrument are detected as analog signals by a pickup device. A portion of the detected signal is extracted, has its voltage adjusted, is converted into a digital signal, and is read into a CPU as a digital signal within a range of 0-5 volts. An amplification factor of the digital signal is determined according to sound volume data included in accompaniment data stored within the accompaniment system, and the proportion of sound volume between the player's performance and an automatically generated accompaniment is adjusted by multiplying the sound volume of the player's performance, or of the accompaniment, by the amplification factor. The sound volume adjustment is effected only once and only when an automatic balancing switch provided on the instrument is depressed.

Abstract: A wavetable audio synthesizer with means for eliminating zipper noise caused by large volume increments, especially at slower rates of volume increment. The wavetable audio synthesizer includes shift circuitry which stores the value of volume increment in binary format and shifts the value right when the shift circuitry is enabled. Shifting the increment value right divides the value by an amount based on the number of bit positions shifted. For example, in the preferred embodiment, the volume increment value is shifted right three positions, thereby dividing it by three and effectively reducing the increment value. When the synthesizer is programmed to increment the volume at a slow rate, preferably the shift circuitry is automatically enabled. Those volume increment bits which are shifted right may be added to the current value of the volume to provide more resolution to this value.

Abstract: The sound volume controlling apparatus comprises UP and DOWN keys (42, 43) depressed manually; a time period detecting circuit (39h, 39d) for detecting time period from when the duration of UP or DOWN key depression reaches a predetermined value (e.g. 0.5 sec) to when the continuous key depression ends; a sound volume value deciding circuit (39e, 39f, 37a) for changing the sound volume value during the time duration detected by the time period detecting circuit; and sound volume changing circuit (37b, 45) for changing the sound volume in accordance with the value decided by the sound volume value deciding circuit.Since the sound volume is changed only after the key is kept depressed for a predetermined time period (e.g. 0.5 sec), it is possible to prevent the sound volume from being changed erroneously due to a short time touch to the keys.

Abstract: A musical-tone-control apparatus having a baton which is provided with an acceleration sensor, and which is swung by a performer is provided. The intensity of a swing of the baton is detected by the acceleration sensor, and controls the tone-generation timing and tone elements such as tone pitches, tone volumes, or tone colors. The intensity of a swing is detected after a predetermined interval has elapsed from the beginning of a swing. As a result, a delay of detection of the intensity due to the inertia of the swing is eliminated. Hence, the swings and the tone-generating timing of musical tones are in harmony, which allows the performer to enjoy a natural feeling of performance.

Abstract: The distortion pedal for electric guitar and other electronic musical instruments employs vacuum tube circuitry operated by low voltage "battery eliminator" DC power supply.

Abstract: When picking of a string is performed, the vibration of the string is detected accurately and quickly. When a fret operation position is changed during generation of a musical tone caused by the string picking, the pitch of the musical tone is changed to the one corresponding to the new fret operation position without generating a new musical tone. When the same string is stroked successively, the succeeding musical tone is generated while keeping the reverberation of the previous musical tone. The musical tone once generated will be stopped from being generated upon elapse of a predetermined time from the beginning of the tone generation, irrespective of the type of its timbre. When a fret operation state is changed to an open-string operation state after the string picking, the generation of the musical tone being generated stops at that timing.

Abstract: An apparatus for controlling the sound volume of an electronic musical instrument has a row of volume select depress switches. In response to depression of any one switch, a corresponding sound volume is produced. The sould volume increases for each successive switch along the row. If two successive switches are depressed simultaneously, a sound volume is produced which is intermediate the sound volume produced by depression of one switch only and the sound volume produced by depression of the adjacent switch only. A corresponding row of volume indicators is provided. In response to depression of one of the switches, the volume indicator corresponding to the sound volume of the depressed switch and all of the volume indicators corresponding to the not depressed switches having a sound volume less than that of the depressed switch are activated.

Abstract: An electronic musical instrument includes a keyboard, a first tone generator, a second tone generator, a hold switch, and a control unit. The keyboard designates a pitch of a musical tone to be generated. The first tone generator generates a first musical tone signal corresponding to the pitch designated by the keyboard. The second tone generator generates a second musical tone signal corresponding to the pitch designated by the keyboard. The hold switch generates a pitch hold command. When the pitch hold command is generated, the control unit inhibits a pitch change in the second musical tone signal generated by the second tone generator to hold a predetermined pitch.
