Abstract: A system in which a AV data stored in an AV server is previewed by a plurality of edit terminals includes a recording apparatus which is connected to those edit terminals and which is capable of higher speed access than a recording element in the AV server, and a first processing element which makes a request to transfer AV data from the AV server to the recording apparatus and a second processing element which previews AV data from the recording apparatus are provided for each of the edit terminals. Accordingly, a material stored in the AV server can be previewed by the plurality of edit terminals simultaneously in parallel without being limited to the number of the input and output ports of the AV server, and the waiting time becomes short when the edit terminal previews the material stored in the AV server.

Abstract: A digital piano apparatus includes an input unit including a plurality of keys and a plurality of pedals, a sound source unit, a sound field synthesizing unit, and a speaker unit. The sound field synthesizing unit includes virtual sound source spot signal generating means for generating a plurality of virtual sound source spot signals of a number equivalent to the number of output channels in the speaker unit, the plurality of virtual sound source spot signals being used for forming reproduced sound fields of a grand piano on the basis of a plurality of tone signals supplied from the sound source unit; mixing means for mixing each virtual sound source spot signal with the remaining virtual sound source spot signals; and sound effect means for applying a sound effect by signal processing using impulse responses to the virtual sound source spot signals.

Abstract: Disclosed is a piano sound source apparatus for adding a piano sound source providing a plurality of sinusoidal oscillation frequencies and a noise source providing a plurality of noise oscillation frequencies to output a composite tone. The apparatus includes an oscillation control unit that controls the frequency and amplitude of each of sine waves corresponding to the sinusoidal oscillation frequencies on the basis of time, an amplitude control unit that controls the amplitude of each of the sine waves corresponding to the sinusoidal oscillation frequencies in accordance with the intensity of the composite tone, and a mixing-proportion control unit that controls the amplitude of each of the noise oscillation frequencies in accordance with the intensity of the composite tone to control the mixing proportion of the amplitudes of the noise oscillation frequencies and those of the sine waves corresponding to the sinusoidal oscillation frequencies.
