Abstract

A musical performance apparatus is provided with a tone generation circuit 15 and a sound system 16 for emitting musical tones of musical instruments and control tones corresponding to musical score data SD which controls a musical score display apparatus 20 . The tone generation circuit 15 has a tone volume adjustment circuit 15 a 3 which changes tone volume of only the musical tones in accordance with player's instruction and maintains tone volume of the control tones at a certain tone volume. The tone generation circuit 15 also has a pan adjustment circuit 15 a 4 which localizes the control tones so that the control tones will be emitted only from a certain speaker. Furthermore, the musical performance apparatus is designed such that the control tones are formed only of frequency components included in a certain high frequency band. Furthermore, the tone volume of frequency components which are included in frequency components representative of the musical tones and are further included in the certain high frequency band is controlled to be lower than the tone volume of the control tones.

First claim

What is claimed is:

1. A musical performance apparatus comprising:
a tone generating portion configured to emit a musical tone of a musical instrument and a control tone which is formed only of a frequency component included in a certain high frequency band and corresponds to control data for controlling an external apparatus, and including a tone volume changing portion configured to change tone volume only of the musical tone in accordance with player's instruction while maintaining tone volume of the control tone at a certain tone volume,
wherein
a first mode in which only the musical tone is emitted and a second mode in which the musical tone and the control tone are emitted are provided,
the tone generating portion includes a plurality of tone generation channels to generate the musical tone or the control tone so that all of the tone generation channels will generate the musical tone in the first mode while at least one of the tone generation channels will generate the control tone in the second mode, the at least one of the tone generation channels being configured to read out waveform data from a memory and generate the control tone based on the read out waveform data, and
the tone generation portion further includes a plurality of tone volume adjustment circuits configured to respectively receive an output from the tone generation channels, and in the second mode, a tone volume adjustment circuit connected to the at least one of the tone generation channels has a non-adjustable value for a tone volume setting parameter while the other of the tone volume adjustment circuits have an adjustable value for the tone volume setting parameter.

2. The musical performance apparatus according to claim 1 , wherein the tone generating portion includes:
a plurality of speakers for emitting the musical tone and the control tone; and
a localization setting portion configured to localize a sound image of the control tone at a certain position by setting respective tone volumes of the control tone which is to be emitted from the speakers at certain tone volumes, respectively.

3. The musical performance apparatus according to claim 2 , wherein the localization setting portion allows the control tone to be emitted only from one speaker which is selected from the plurality of speakers.

4. The musical performance apparatus according to claim 1 , wherein tone volume of a frequency component which is included in frequency components of the musical tone and is further included in the certain high frequency band is lower than the tone volume of the control tone.

5. The musical performance apparatus according to claim 1 , wherein the control tone is a modulated tone obtained by modulating a carrier wave by use of the control data.

6. The musical performance apparatus according to claim 1 , wherein the tone generating portion further includes a tone pitch changing portion configured to change a tone pitch only of the musical tone in accordance with the player's instruction while maintaining a tone pitch of the control tone at a certain tone pitch.

7. The musical performance apparatus according to claim 1 , wherein the tone generating portion further includes a tone color changing portion configured to change a tone color only of the musical tone in accordance with the player's instruction while maintaining tone color of the control tone at a certain tone color.

8. The musical performance apparatus according to claim 1 , wherein
the external apparatus includes a display unit to display a score; and
the control data includes a score page designating data which designates a page position of the score to be displayed on the display unit.

9. The musical performance apparatus according to claim 8 , wherein the score page designating data is generated by spreading the data representative of the page position of the score to be displayed on the display unit and modulating the spread data by using differential phase shift modulation scheme.
