Abstract:
A waveform producing method comprising the steps of:receiving style-of-rendition stream data including a time series of packets, each including a vector ID and time information, at least one of the packets including modifying information, each of the packets corresponding to any one of a plurality of styles of rendition; reading out stored data indicative of a waveform shape variation over time on the basis of the vector IDs in the packets included in the style-of-rendition stream data received by said step of receiving; modifying said data indicative of a waveform shape variation over time read out by said step of reading out on the basis of the modifying information; arranging, at time positions, said data indicative of a waveform shape variation over time modified by said step of modifying on the basis of time information included in the packets; and producing waveforms corresponding to the styles of rendition corresponding to the time series of packets on the basis of said data indicative of a waveform shape variation over time arranged at the time positions by said step of arranging.
