Abstract:
1. A performance data processing method comprising: a step of receiving a series of performance data; a detection step of detecting a predetermined type of note controlling performance data from among the series of performance data received by said step of receiving, the predetermined type of note controlling performance data including a control value of a predetermined tone characteristic of a note; a setting step of, each time the predetermined type of note controlling performance data is detected, setting deviation values for a plurality of channels presenting mutually different deviation states, in order to cause the control value of the predetermined tone characteristic of the note to vary each time the predetermined type of note controlling performance data is detected; and a generation step of, each time the predetermined type of note controlling performance data is detected, causing the control value of the predetermined tone characteristic of the note, included in the detected predetermined type of note controlling performance data, to vary among the plurality of channels in accordance with respective ones of the deviation values of the channels, set by said setting step, so as to obtain channel-specific control values, and generating, for individual ones of the channels, the channel-specific control values as new control values of the predetermined tone characteristic of the note, wherein note controlling performance data of the predetermined type having the new control values of the predetermined tone characteristic of the note, generated by said generation step, are created for the plurality of channels.
