摘要： Each of a plurality of channels includes a sample counter adapted to perform counting operation at a given rate. Independently for each channel, a control section (CT) sets the rate and an initial value for the counter of the channel and controls start and stop of the counting operation of the counter, so that a partial portion of an original waveform corresponding to a count range from the set initial value to a count stop point is reproduced in the channel. The control section sets the initial values in individual ones of a set of channels, selected from among the channels, such that sample values at different sample positions of the original waveform are simultaneously retrieved in individual ones of the set of channels, and controls an overlap adder (OLA) to add up the retrieved sample values, so that sample values of an audio waveform signal with a plurality of partial portions of the original waveform, which are to be reproduced in the set of channels, partially overlapping each other are output from the adder. By the overlapping between the plurality of partial portions of the original waveform, a reproduction time length and/or tone pitch can be readily controlled, and formant control can be performed in accordance with the given rate.

摘要： A waveform data structure includes a plurality of types of frames having different data sizes. Each of the plurality of types of frames includes an auxiliary information area and a data area. The auxiliary information area includes an area for storing common effective-bit length data for a section of waveform samples, and an area for storing an identifier for identifying one of the plurality of types of frames. The data area is an area for storing waveform samples extracted based on a common effective-bit length. The number of the extracted waveform samples in each frame is determined based on a common effective-bit length and on the size of the frame. In case a waveform varies rapidly ( attack ), the numbers of code bits of a lot of waveform samples having various bit lengths increase: A small frame size is more efficient to convert data in response to variation in the waveform; but as the number of frames increases ( sustain ), the amount of redundant header information increases. In case a waveform slowly varies, the bit lengths of the waveform samples can be decreased and a large frame size reduces the number of header accesses. The auxiliary information area further includes an area for storing a sound volume correction parameter for correcting the sound volume of the extracted waveform samples stored in the data area when the compression ratio is changed, for instance to store lower quality, lower volume samples during the sustain portion, higher quality same volume samples during the attack portion, in order to further save memory area.

摘要： In an apparatus capable of generating a tone by a plurality of different tone generation processing modes, the respective tone generation processing modes are arbitrarily assigned in units of tone generation channels by a selector (4). In particular, as one of the tone generation processing modes, a waveform readout processing such as a PCM method is used. Another processing mode converts an output (x) obtained by mixing a modulation signal with a carrier signal (x) in accordance with a predetermined functional relationship to a tone signal. In this mode, when the mixing ratio is set to be a predetermined value, the tone signal has a sine or cosine wave. Various tones such as a tone including a single sine or cosine wave component, a tone including harmonic components of high orders, and the like can be widely synthesized, and can be desirably assigned to the tone generation channels. The tone signals synthesized by the two tone generation processing modes are mixed at a predetermined mixing ratio which changes over time, and the mixed signal is output as a mixed tone signal.

摘要： A musical tone signal generating apparatus provides at least a waveform memory (2) which stores a plurality of fundamental waveform data based on three-dimensional coordinate address system having three coordinate axes to which respective musical tone control parameters are assigned respectively. The desirable fundamental waveform data is read out at an address corresponding to a coordinate position determined by selecting desirable musical tone control parameters. Then, an interpolation operation is carried out on the fundamental waveform data which are sequentially read out so that an interpolated musical tone waveform signal is formed. The waveform of the interpolated musical tone waveform signal is similar to and intermediate to the waveforms of the fundamental waveform data to be synthesized. Thus, the interpolated musical tone waveform signal is converted into a musical tone signal, by which corresponding musical tone is to be sounded.

摘要： A full waveshape of a musical tone to be produced from the start to the end of sounding or a rise portion and a part of the waveshape following the rise portion of the musical tone is stored in a waveshape memory (12), and the musical tone is formed by reading out the waveshape from the waveform memory once, or reading out the rise portion once and thereafter reading out the partial waveshape repeatedly. A digital filter (14) is introduced following the waveshape memory (12) in this tone-producing device. The filter characteristics are determined in accordance with a tone color change parameter such as the key touch or the tone pitch of the musical tone, thereby realizing a tone color change of the muscial tone. Further, in order to realize timewise change of tone color of the musical tone, circuit which lets the tone color change parameter vary with time is proposed.
