<P>PROBLEM TO BE SOLVED: To set a key of automatic musical playing and to easily play a musical piece ranging over a plurality of octaves. <P>SOLUTION: Playing data of a selected musical piece are read out of a storage section 10 and a key detection section 11 detects the key. A key correspondence table of a basic key that the detected key belongs to is read out of a note number/display key storage section 13 and note numbers of the key correspondence table are shifted by the difference in note number between the key read out of the note number display key storage section 13 and detected and the basic key to generate a display key correspondence table of the detected key. A playing data display key conversion section 15 converts playing data of a predetermined section into a display key by referring to the display key correspondence table, and the display key is displayed at a display section 17. When the number key of an operator 18 that the displayed display key designates is operated, a note-on of corresponding playing data is sent to a sound source section 20 to generate a sound. <P>COPYRIGHT: (C)2008,JPO&INPIT |
