摘要： A record and reproduction controlling device is connected to a hard disk memory via a bus. This controlling device receives from a computer information necessary for read/write operation, on the basis of which the controlling device performs its own process to write to or read from the hard disk. The record and reproduction controlling device temporarily stores tone data read out from the hard disk memory into a first buffer memory and then transfers the tone data from the first buffer memory to a second buffer memory. The tone data thus stored in the second memory is then read out at a predetermined readout rate to reproduce a musical sound. It is possible to select either a first reproduction mode for reproducing a data file having tone data of plural channels recorded in an interleaved state, or a second reproduction mode for permitting a simultaneous reproduction of plural data files each having not-interleaved tone data recorded therein. The controlling device controls the tone data transfer from the first buffer memory to the second buffer memory depending on which of the reproduction modes is employed.

摘要： At least two sets of filter coefficients corresponding to different filter characteristics are interpolated by using a control signal for controlling tone color as a parameter of interpolation. Filter coefficients obtained by the interpolation are supplied to a digital filter to determine its filter characteristics and an input tone signal is modified in accordance with the filter characteristics thus determined. Filter characteristics of diverse variation as compared with the number of prepared filter coefficients can thereby be realized. Further, timewise change of filter characteristics can be realized by changing a parameter of interpolation with lapse of time or changing two sets of filter coefficients to be interpolated with lapse of time. Designation of filter coefficients can be made by designating coordinate data of coordinates having at least two axes. In this case, filter coefficients can be changed by changing coordinate data of at least one axis in accordance with tone color control information whereby filter characteristics can be variably controlled.

摘要： A waveform generating apparatus for generating waveforms which can be suitably employed in electronic musical instruments. The waveform generating apparatus calculates and generates regenerated sample data of a regenerated waveform having a desired pitch in synchronization with a constant regeneration sampling interval based on basic sample data which are sampled from a basic waveform by a predetermined basic sampling interval. The apparatus includes a phase generator, an operation mode control circuit and an interpolating circuit. The phase generator generates phase data which designates a phase of basic waveform. The operation mode control circuit supplies a calculation designating data. The interpolating circuit calculates regenerated sample data on the basis of basic sample data and phase data. Wherein, the method of the interpolation which is performed by the interpolating circuit is altered in response to calculation designating data. Thus, waveform can be regenerated accurately and with high fidelity over a wide range of pitches.

摘要： A musical tone generating apparatus is provided for an electronic musical instrument. The apparatus comprises a musical tone signal generating device and a parameter controller. The musical tone signal generating device generates a musical tone signal characterized by a tone parameter whose value is supplied from the parameter controller. The parameter controller comprises a target value generator and an interpolation device, which operate independently. The target value generator generates a target value of the tone parameter to the interpolation device, and the interpolation device interpolates between a present value of the tone parameter and the target value, so that the present value is renewed consecutively. The interpolation device generates an interrupt signal to the target value generator when the present value reaches the target value, so that an operation of the target value generator is interrupted then the target value generator operates to generate a new target value to the interpolation device in response to the interrupt signal. The parameter controller changes a characteristic of the musical tone signal such as a frequency characteristic or amplitude with respect to a lapse of time based on the present value of the tone parameter.

摘要： A musical tone generating apparatus is provided for a keyboard electronic musical instrument. The apparatus consists of a musical tone source, a coefficient generator, a digital filter and so on. The coefficient generator generates at least one time dependence coefficient, and applies It to output of the digital filter. The parameter controller changes at least one parameter, which designates tone color of the musical tone, in accordance with the time dependent coefficient to thereby realize time-variant changing rate of envelope of musical tone. And, the coefficient generator and the parameter controller are used by means of time sharing technique. That is, the coefficient is used as plural units, wherein each unit generates a coefficient in each stage, and the digital filter is also used as plural units. Each digital filter unit changes a parameter of tone color of the musical tone in accordance with the coefficient supplied thereto.
