Abstract:
A digital signal processing method comprising a step of reproducing a performance tone signal based on interface data for an instrumental performance, which contains at least performance data for an instrumental performance, which contains at least performance data for causing a sound source storing plural pieces of instrumental tone information to generate a performance tone of an instrument, and a digital signal other than the performance tone signal, on the basis of control data previously encoded and described in the interface data, wherein the interface data includes an indication of a type of the digital signal other than the performance tone signal, and wherein the type comprises one of an audio signal, an image signal, and a text signal;wherein the control data is previously described as an encoded data string in a predetermined event in a standard format of the interface data; and wherein the control data is described before a timing at which the control data is desired to be controlled, and timing information which is desired to be actually controlled is added in the control data.
