摘要:
A tying method and apparatus which is carried to easily automatically band bar-like articles such as reinforcements or pipes and various other articles by a linear tying material. The apparatus comprises tying material feed means (6), tying material bending means (8), encompassing and guiding means (9), tying material cutting means (7) and twisting means (11), wherein a starting point is formed in a way such that a part of a continuous linear tying material w delivered from the tying material feed means comes into engagement with the tying material bending means so that the tying material is bonded into a U-shape. In that state, the tying material is delivered from one side whereby the tying material is guided around an article to be tied by the encompassing and guiding means (9) while being bended into a substantially U-shape. The tying material is cut into a predetermined length, and both ends of the tying material are twisted together by a hook (25) of the twisting means (11). Since the tying material is automatically bended to form two strands and the tying is done only once thereby, the strength of the tying material is enhanced and the rigid tying can be made with a materially strong tying force. Further, since the twisting advances from the hook side toward the article to be tied, the twisting can be advanced till a looseness in the tying portion of the article to be tied disappears, thus enabling the strong tying.

Disclosed is a tone generating apparatus which is provided with a timbre select switch to specify a timbre and a scan circuit for generating key codes corresponding to keys. Pitch control values corresponding to the timbres and key codes are stored in the form of a pitch control table in a ROM. When a predetermined key is depressed, a pitch control value specified by the key code associated with that key and the timbre selected by the timbre select switch is read out from the pitch control table in the ROM, and a tone frequency is determined by the pitch control value and key code. Tone generation is controlled based on the tone frequency.A pitch control value read out from the pitch control table in the ROM is given a predetermined offset to produce a musical tone having vibrato.Further, a pitch control value read out from the pitch control table in the ROM is multiplied by a value specified by an operation panel to alter the degree of adding the pitch.

An electronic musical instrument, including a tone generator for forming play tones and accompaniment tones according to tone source data read out from a waveform memory based on keyboard operations or auto-accompaniment data stored in a memory. The electronic musical instrument further includes a large number of operation switches on a panel for inputting tone parameters such as rhythm, tone color (type of instrument), tempo, and a display for displaying set tone parameters. Voice and character data representing the functions or specifications of the musical instrument, the operation guidelines of the operation switches, or the current setting state of the musical instrument, are stored in a memory. When a user performs a specific operation and requires assistance, voice data and character data are supplied to the tone generator and the display, and the user can visually and aurally recognize the functions or operation guidelines of the musical instrument.

An automatic playing device has a memory which stores sequence data consisting of musical sound data and sequence data to control read-out of the musical sound data. A processing unit repeatedly reads out musical sound data specified by the control data included in the sequence data stored in the memory. A movement instruction switch gives instructions for movement of an accompaniment part to be played. A control device terminates, when an instruction for movement of a part to be played is issued by the movement instruction switch, the operation to repeatedly read out musical sound data if musical sound data stored in the memory is being repeatedly read out by the processing unit. In this case, the control device moves system operation to read out the next sequence data. For example, automatic accompaniment is made by sequentially reading out sequence data stored in the memory, and, for instance, accompaniment to improvisation is realized by repeatedly reading out a portion specified by the control data stored in the memory. Thus, if the player wishes to go out of the improvisation part and gives an instruction for movement of an accompaniment part to be played with the movement instruction switch, system operation goes to an operation to read out the next sequence data.

Disclosed are a chord detecting/storing apparatus and an accompaniment information processing apparatus. The chord detecting/storing apparatus designates tones consisting of a chord on a keyboard, and extracts one of the designated notes. Based on the extracted note, the apparatus prepares a row of note bits excluding at least one note. Using this note bit row as an address, the apparatus searches for a chord table in advance where chord information is stored to correspond to each pattern for a row of note bits, and reads out searched chord information to detect a chord.The accompaniment information processing apparatus detects component tones of a chord when the chord is designated from the keyboard, and generates chord information. The accompaniment information processing apparatus produces specific tone information in association with the generated chord information and correlates the specific tone information with the chord information before storing both information items.

An interruption control apparatus for controlling interruptions of a performance information processor for processing performance information of a piece of music. The interruption control apparatus includes a first time control unit for regulating the length of a time interval between successive interruptions of the performance information processor according to a pre-set tempo in such a manner that the regulated time interval is limited within a predetermined constant range, and for outputting an interruption signal at the regulated time interval; a second time control unit for receiving the interruption signal and increasing a parameter of a register by an increment, of which the value varies inversely as the pre-set tempo, every reception of the interruption signal and further transferring performance information to the performance information processor each time the parameter reaches a predetermined value and then resetting the parameter to become zero; and an interruption processing unit for receiving the interruption signal and interrupting the performance information processor in response to the received interruption signal.
摘要:
Truncate processing is performed so that a new tone is not generated before the envelope waveform is finished but the new tone is produced after the volume of the previous tone is sufficiently diminished, by which the new tone can be produced with a satisfactory feeling of attack. Further, the envelope waveform is not abruptly interrupted and cleared in a moment but is decayed at a constant and high speed, thereby preventing the generation of noise such as a click. Moreover, demanded speed data is provided for each tone, by which it is possible to produce repective tones not at a demanded speed like the least common multiple but at an optimum speed for each tone and to make the previous tone generation proceed to the next tone generation without producing noise such as a click.
