May be omitted so that the lengths match.

FIG. 7 shows a third example of the performance guide processing. In this example, the performance guide is performed by voice by generating the name of the sound to be generated.

When the user selects a desired song from the database in the same manner as described above, song data representing the melody of the selected song is written to the storage unit 16A.
The music data includes on-timing data representing generation timing, note-length data representing note length, and note-on event data representing pitch for each note to be generated, and off-timing representing deletion timing for each note to be deleted. It contains data and note-off event data representing the pitch. The sounding length data is represented by 1 if the length of the sounding period is longer than a quarter note length, for example, and is represented by 0 if it is shorter than the quarter note length.

[0076] In the step _{S 21} performs the name specified processing. The user designates either a floor name or a sound name as a name to be pronounced by operating the manipulators of the manipulator group 38, and specifies a special name for the specified name. If the designated name is a floor name such as “Doremi Fasorashi”, the special name is a special floor name, for example, “A”, “A”,
Specify a special floor name such as "I", "U" ... If the specified name is a sound name such as "Sea, Dee, E, ... Be", the special name will be a special sound name,
Special floor names such as "ta", "chi", "tu", etc. are designated corresponding to "D", "F", respectively. The specified special floor name or special sound name can be changed. For example, “na”, “d”, “nu”,... Can be designated corresponding to “do”, “ray”, “fa”, respectively. Such designation can be either collective designation or individual designation for “Do, Re ...”.

The name.

[0079] In the step _{S 25,} performs a name pronunciation processing. One tone generation control data of note-on event data, time length data, and a tone generation instruction signal relating to the conversion is supplied to the tone generator circuit 24 and assigned to one of the free tone generation channels. In the tone generation channel related to the assignment, the sound length (for example, short sound length) indicated by the sound length data of the two sound data corresponding to the name (for example, floor name “A”) indicated by the note-on event data for conversion. Is generated on the basis of the voice data corresponding to the name (e.g., short "A").
Thereafter, the mute control data for one sound composed of the note-off event data relating to the conversion and the mute command signal is transmitted to the sound source circuit 2.
4 to start attenuating the audio signal in response to the mute command signal in the tone generation channel which is generating the name represented by the note-off event data. At this time, a release waveform may be given by the envelope generator so that the sound is attenuated smoothly. With the above-described processing, it is possible to generate floor names and special floor names (or note names and special note names).

According to the processing shown in FIG. 7, the keyboard 3 is played according to the performance guide based on the floor name or note name while listening to the automatic performance of the music.
A performance practice can be performed with the performance operation unit 36 such as 6A. For notes with accidentals, names other than floor names or note names, such as "A", "I", and "U", which are shorter than accidentals, are pronounced. It can be clearly recognized. In addition, since short names are pronounced based on audio data having a short pronunciation length and long names are pronounced based on audio data having a long pronunciation length, a performance guide that is easy to hear can be realized.

In the processing shown in FIG. 7, a plurality of voice data are stored and selectively reproduced corresponding to the length of the pronunciation length of the vowel and the consonant only, and one voice data is stored for the vowel. Alternatively, the reproduction may be performed as it is in response to the short pronunciation length, and may be repeatedly performed in response to the long pronunciation length. When a plurality of voice data are stored for one name, three or more voice data such as long / medium / short, not only long / short, are stored and selectively reproduced. You may.

As the note length data stored in the storage section 16A, note length data or note length data represented by numerical values such as the number of clocks may be used. In this case, in step _{S 25,}
Judgment is made based on the pronunciation length data to determine whether the pronunciation length is long or short. I just need. As the music data, storing those representing the pitch syllable names or pitch name instead of the storage unit 16A, performs automatic performance by converting syllable names or pitch name in step S ₂₃ to pitch, step it may be to pronounce the S ₂₅ in the syllable names or sound name. In this case, step S
The pitch / name conversion process of step ₂₄ becomes unnecessary, and step S
_21, S the process ₂₄ in order to change the designation of special floor name or special note name may be performed.
