  • Patent number: 5880386
    Abstract: In each of terminal devices, there is stored user profile information on the corresponding device. The user profile information includes data identifying the user, type and name of the device, information regarding a CPU, memory and operating system (OS) provided in the device, and information regarding various data and program stored in the device. When desired musical information data is to be downloaded from a host computer, a request for downloading optimum data is sent to the host computer. This permits efficient loading of data most suitable for system conditions. When data or program is to be loaded from a recording medium, such as a CD-ROM, rather than a communication network, efficient loading is permitted in a similar manner.

  • Patent number: 5714703
    Abstract: A musical sound generating apparatus creates a waveform to generate a musical sound according to performance information. In the apparatus, a first waveform generator is operable for creating a waveform. A second waveform generator is operable independently from the first waveform generator for creating a waveform. An input device provides performance information. A designating device designates at least one of the first waveform generator and the second waveform generator in correspondence with the provided performance information. A controller selectively operates the designated one of the first waveform generator and the second waveform generator to create the waveform according to the provided performance information. An output device generates the musical sound based on the created waveform.

  • Patent number: 5687105
    Abstract: A digital signal processor (i.e., DSP) is employed by an electronic musical instrument. The contents of operational processes to be executed by the DSP can be arbitrarily set in accordance with filtering operations of the filters to be realized. A processing device to be embodied by the DSP at least contains a microprogram memory, a coefficient register, a delay memory and a processing portion. A desired set of coefficients are read from the coefficient register in accordance with a first address signal, while a desired program is read from the microprogram memory in accordance with a second address signal. Each program contains at least one operational command or one instruction. The value of each of the first and second address signals is periodically changed in each sampling period.

  • Patent number: 5578780
    Abstract: A sound synthesis system, having a pitch adjusting function, comprises a pitch adjusting portion and a loop including a tone-color forming portion and a delay portion. A signal circulating through the loop is delayed using an amount of delay by the delay portion; and then, the tone-color forming portion imparts a tone-color characteristic to the signal delayed so as to produce a sound signal. In the pitch adjusting portion, a pitch of the sound signal is detected; and an initial constant is generated based on a designated pitch and/or a designated tone color. The initial constant represents an initial delay effected by the delay portion. In addition, an amount of correction is created based on a difference between the pitch detected and the designated pitch. Thus, the amount of delay of the delay portion is corrected by using the amount of correction in such a way that the pitch of the sound signal is automatically adjusted to be equal to the designated pitch in real time.

  • Patent number: 5442127
    Abstract: A memory stores waveform sample data for plural sample points forming a given tone waveform, and one of the stored waveform sample data stored for every two adjacent sample points is expressed in PCM representation while the other is in difference value representation that is based on the PCM values stored for two sample points on both sides of the sample point of the other sample data. The number of bits in each address of the memory is greater than the number of bits in each of the PCM data, and each of the PCM data is stored at some bit positions of one address, while the difference value data is stored at the remaining bit positions of one or more addresses.
