<P>PROBLEM TO BE SOLVED: To provide a performance information input/output device facilitating readjustment of each pitch upon performance. <P>SOLUTION: In response to the completion of storage of pitch information for all of storage areas (S1 to S4), a step sequencer part 30 detects the reference pitch information of one tone of the lowest pitch (or the highest pitch) on the basis of the storage content of each storage area, and stores it in a base note storage area 34. A note data extraction part 20 extracts the pitch information of a certain tone according to extraction rules on the basis of the pitch information of the plurality of tones given by the operation of a keyboard part 10. The step sequencer part 30 acquires the amount of shift between the pitch indicated by the reference pitch information and the pitch indicated by the extracted pitch information, sequentially reads out the pitch information stored in respective storage areas, and outputs the sound corresponding to the shifted pitch by the amount of the acquired amount of shift with respect to the pitch indicated by the pitch information read out. <P>COPYRIGHT: (C)2007,JPO&INPIT |
