摘要： Special-type tone generators are capable of tone generation corresponding to rendition-style designating data, while ordinary-type tone generators are incapable of such tone generation corresponding to rendition-style designating data. When performance data for the ordinary-type tone generator are acquired in a case where the special-type tone generator can be used, presence of a predetermined rendition style is detected on the basis of various control data included in the performance data, the control data in a portion of the performance data, corresponding to the predetermined rendition style, is converted into simple data that does not represent the predetermined rendition style, and also rendition-style designating data specifying the predetermined rendition style is added. In this way, the acquired performance data are reformed into performance data for the special-type tone generator. Conversely, when performance data for the special-type tone generator are acquired in a case where the special-type tone generator can not be used, rendition-style designating data is deleted from the acquired performance data, and tone control data is added, in place of the rendition-style designating data, so as to achieve a desired rendition style. In this way, the acquired performance data are reformed into performance data for the ordinary-type tone generator.

摘要： An electronic keyboard musical instrument capable of performing delicate sound board vibration control based on outputs generated individually for respective ones of transducers, thereby realizing production of natural sounds with sufficient volume, and an easy tone quality adjustment. A sound board is fixed to a frame, and the transducers are mounted to the sound board so as to be spaced from one another. In accordance with first and second performance signals generated in response to a key operation of a keyboard and a damper pedal operation, driving signals for the transducers are individually generated in consideration of characteristics and mounting positions of the transducers, and the driving signals are supplied to the transducers. The sound board is thereby caused to vibrate at a frequency varying according to a tone pitch, thus producing a musical tone and/or a damper tone.

摘要： A storage of DSP receives and stores a plurality of signal processing modules according to which a digital tone signal is processed. Each signal processing module includes a plurality of data groups (e.g., program, fixed data, work data). The storage has a plurality of storage areas, each assigned to a different one of the data groups. Each storage area is divided into a plurality of division areas for the plurality of signal processing modules. DSP receives address qualifying information on the difference between the size of a specified data groups (e.g., work data) for a signal processing module and the size of a specified division area which stores the specified data group. DSP sequentially executes the plurality of signal processing modules. When it has completed executing of the current signal processing module, DSP uses the address qualifying information to determine the start address of the specified division area for the next signal processing module.

摘要： In generating tone waveform data for each fixed or variable section via software of a personal computer or the like, a generation start condition is changed depending on an application of the waveform data. When the waveform data is to be sounded in real time, various programs are activated in synchronism with predetermined cycles, such as tempo clock and frame cycles, in order to generate the waveform data at accurate timing. When, on the other hand, the waveform data is to be recorded in a waveform file, various programs are activated on condition that waveform data generation processing has already been completed for a preceding section. Such arrangements can eliminate limitations to processing times of the programs and thereby provide a tone waveform of high accuracy.

摘要： A music apparatus has a central processor, a plurality of generator modules, and a program memory storing instructions for causing the central processor to execute a process of synthesizing a musical tone signal with the generator modules. The process includes the steps of commanding each of the generator modules to generate a predetermined number of samples of the musical tone signal at a common sampling period, and collecting the samples from each of the generator modules and processing the collected samples at the common sampling period to thereby synthesize the musical tone signal. The generator modules include a synchronous generator module that does generate the predetermined number of the samples at the common sampling period, and an asynchronous generator module that does not generate the predetermined number of the samples at the common sampling period. The asynchronous generator module is commanded to perform the steps of generating an equivalent number of samples at a local sampling period, and converting the equivalent number of the samples arranged at the local sampling period into the predetermined number of the samples arranged at the common sampling period to thereby pass the predetermined number of the samples to the collecting step at the common sampling period.

摘要： Basic tone waveform corresponding to a designated tone color and pitch is generated in each of a plurality of channels. Effect is imparted to the basic tone waveform in accordance with an algorithm for providing a predetermined effect, independently for each of the channels. The effect to be imparted is controlled in accordance with the designated tone pitch, separately for each of the channels. The effect impartment may be conducted using a processor, such as a DSP, executing a predetermined program containing a predetermined effect-imparting algorithm. In one example of the effect-imparting algorithm, a delay loop is employed through which an input exciting signal is circulated while being delayed, and an effect specific to an electromagnetic pickup of an electric guitar can be approximated by controlling the delay amount in the delay loop. In another example of the effect-imparting algorithm, a ransom signal is generated to control a cutoff frequency on the basis of the random signal, the basic tone waveform is filtered in accordance with the thus-controlled cutoff frequency, and the resultant filtered tone waveform is circulated through a delay loop whose delay amount is controlled in accordance with the designated tone pitch.
