PURPOSE:To provide sheet-of-music information which is natural in musical terms by analyzing the playing information about melody etc. CONSTITUTION:The key-on timing data, treble data, and gate time (sound emission duration) data are stored sound by sound, for example S1, S2, etc., in an input memory part of a memory 20. In the buffer memory part of this memory 20, the key-on interval data corresponding to the difference Tk=K2-K1 of key-on timing values is stored in combination with the treble data sound by sound. The tempo, the time pattern, and the measure line position to suit the specified conditions are determined on the basis of the data obtained by converting the key-on interval data into the note length. Each piece of gate time data is converted into the note length data according to the tempo, and these pieces of note length data are stored in the output memory part of the memory 20 together with the measure line information B1, B2 conforming to the time pattern and measure line position in combination with the treble data sound by sound. The stored contents of this output memory part are displayed or printed out as sheet-of-music information. |
