An electronic musical instrument of a type wherein a plurality of systems are provided each system comprising memories storing respective harmonic component waveshapes which are read at the same reading rate and the read out harmonic waveshapes are suitably mixed to obtain a desired musical tone. Each system also comprises a circuit for controlling the envelope of the waveshapes read from the memories. In the first system, the envelope control is made in such a manner that the envelope will rise upon depression of a key, thereafter maintain a constant level as long as the key is kept depressed and decay upon release of the depressed key. In the second system, the envelope is controlled so that the envelope will rise in a short time and immediately decay thereafter. The respective harmonic waveshapes thus controlled in envelope in the respective systems are then suitably selected and mixed together. As an example of the envelope control in the second system is shown a structure for producing a so-called "chiff" effect by providing the fractional period during which the envelope rises and subsequently falls at the attack portion of the musical tone. Desired waveshape or waveshapes are selected from among the harmonic waveshapes controlled in the envelope in the second system for mixing with the harmonic waveshapes read from the first system. By this arrangement, amplitudes of the frequency components of the selected harmonic waveshapes are emphasized during the fractional period.

A method of transferring a virtual volume established on a real volume includes acquiring transfer source virtual volume information from a transfer source, acquiring transfer destination real volume information from a transfer destination, generating transfer destination virtual volume information from the transfer source virtual volume information by using the transfer destination real volume information, and establishing a virtual volume at the transfer destination based on the transfer destination virtual volume information.

To provide a data generating method, device, and program that can generate drawing data for drawing the entire general design graphic data with an accuracy of about 1 to 4 nm in a drawing method or a drawing system adapted to draw gradation-controllable spotlights in a two-dimensional array.The data generating method is a method for generating, in an exposure system having a function of irradiating multigradation-controllable spotlights in a two-dimensional array onto a photosensitive film on a substrate, gradation values of the spotlights based on design graphic data. Using reference data classified by features of a graphic and describing in advance combinations of gradation values mapped to coordinate information of a graphic, the method discriminates the feature in the design graphic data near positions of the spotlights and selects the combination of the gradation values in the reference data corresponding to coordinate information of the positions of the spotlights, thereby determining the gradation values.

A signal reception circuit capable of detecting and receiving a signal at a high speed having small amplitude, and a data transfer control device and electronic equipment using the same. A differential pair of reception signals DP and DM is detected by an HS_SQ_L circuit for low speed having high receiving sensitivity and an HS_SQ circuit for high speed having high speed response performance. In the case of a high-speed reception signal, a logical product of a signal HS_DataIn fetched by an HS differential data receiver and a signal HS_SQ indicating the result of signal detection by the HS_SQ circuit for high speed is supplied to a DLL circuit. In the case of a low-speed reception signal, an FS differential receiver is activated after the detection of differential pair of reception signals DP and DM by the HS_SQ_L circuit for low speed. A signal FS_DataIn fetched by the FS differential receiver is supplied to an FS circuit.

A window voltage comparator, which determines whether a difference between two voltages is greater or smaller than a set value, is equipped with a first differential pair including a first transistor to which a first input voltage is applied and a second transistor to which a second input voltage is applied, a second differential pair including a third transistor to which a first reference voltage is applied and a fourth transistor to which a second reference voltage is applied, and a comparison circuit that compares the sum of drain currents of the first and fourth transistors with the sum of drain currents of the second and third transistors and thereby determines whether a difference between the first input voltage and the second input voltage is greater or smaller than a set value.

In a fingering information analyzer, tone pitch information indicative of each tone pitch of a series of musical notes supplied from a flexible disc or a performance information memory is analyzed to produce fingering information indicative of a performance finger for each of the musical notes. The fingering information is mixed with the tone pitch information and memorized in a fingering memory. When the fingering information is reproduced, a performance finger for each of the musical notes is determined in accordance with a changing direction or variation width of the tone pitch information continual in time series and a changing condition of white and black keys based on the tone pitch information. The tone pitch information and fingering information memorized in the fingering memory is read out in accordance with progression of a musical tune and adapted for performance of the keys on a keyboard and for indication of the performance finger.

The musical tone control apparatus detects a movement of a player, such as a holding, touching, beating, depressing, pulling, lifting up or down movement. Then, the musical tone control apparatus generates musical tone control data based on a detecting result of the movement of the player. The musical tone control data control a tone pitch, a tone color or a tone volume of a musical tone to be generated.

There is provided a music sheet having a magnetic data recording section. The magnetic data recording section is provided in parallel with a lower edge of the sheet and stores automatic performance data for manual performance, a front surface of the sheet is described with a music including an introduction and an ending, and a rear surface that is described with an advice or guidance for performing the music. The music sheet is convenient not only to a not yet skilled performer but also to a skilled performer in order to perform or exercise the music.

The wear for controlling a musical tone consists of a wear worn by a player, a main body and at least one detector for detecting a certain movement of the player. The main body is mounted at a player's waist, and the detector is mounted at a player's joint by use of a mounting member such as a plane fastener. Hence, the mounting position of the detector can be freely adjusted. The main body and the detector are connected by use of wires which may be sewed in the wear. In addition, the detector may constitute a supporter which can be freely mounted at the player's joint. When the detector detects the movement of the player, such as a bending angle of the player's joint, a tone pitch, a tone volume or a tone color of the musical tone to be generated is controlled based on the detected movement of the player.

An automatic performing apparatus for use in an electronic musical instrument stores chord name data and chord generation timing data to carry out an automatic chord performance. In spite of frequent variations of a chord during the progression of a music piece, repetitive storage of a same chord name data is not required so that the amount of stored data can be reduced, allowing utilization of a memory of a small capacity.
