DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the essential structure of a communication karaoke apparatus according to an embodiment of the present invention, FIG. 2 shows the overall structure, and FIG. 3 shows the detailed structure.

In FIG. 1, music data transmitted through a telephone line, an ISDN line, etc. is temporarily stored in a music data memory and then supplied to the performance information processing device 1 as received data during reproduction. The music data is created in advance in, for example, the MIDI format on the transmission side, and includes sound source control parameters and performance data in each of a plurality of channels corresponding to a plurality of musical instruments of accompaniment performance, and further in a specific channel message or channel. The unnumbered system message contains control parameters for the effector that applies reverb or echo to the finally synthesized accompaniment performance signal.

The sound source control parameters for accompaniment performance, the performance data, and the accompaniment effect parameters in the music data supplied to the performance information processing apparatus 1 are decoded by the performance data reading section 1a and the parameter data reading section 1b, and the sound source is generated. The format is converted into control parameter data, performance data, and effect data of the circuit 2 and sent to the tone generator circuit 2. The data conversion unit 1c uses the MID as described later.
Operates when performing an accompaniment performance of karaoke and an ensemble performance using the I musical instrument.

The tone generator circuit 2 is also called a tone synthesizer (tone generator), and has a digital control oscillator DCO2.
a, a digital control filter DCF2b, a digital control amplifier DCA2c and the like. The tone generator circuit 2 has a plurality of simultaneous tone generation channels (the number of voices) by high-speed digital signal processing, parameters such as tone colors are set for each channel by tone generator control parameters, and tone pitch, tone intensity, envelope, etc. are pronounced by performance data. Control is performed.

Further, the tone generator circuit 2 has an effector 2d, and with respect to the digital audio signal of the accompaniment performance that is channel-synthesized, based on the effect parameters transmitted, the time change of the volume, the time change of the sound quality, the reverb, the delay, The effects of distortion, chorus, and equalization are added, and finally output as a stereo sound signal.
The effector 2d may be configured to apply an effect for each channel according to the effect parameters transmitted for each channel, that is, for each part of the accompaniment performance. In this case, the digital audio signal for each channel after the effect is applied is channel-synthesized to 2
Channel stereo output.

The performance information processing apparatus 1 and the tone generator circuit 2 are controlled by a controller 3 (CPU). Actually, the data processing function of the performance information processing apparatus 1 and the control function of the tone generator circuit 2 are executed by a microcomputer including a controller 3 (CPU) and a program ROM (not shown).

When a performance participant uses the communication karaoke apparatus shown in FIG. 1 to play a part of the music piece, he or she first operates a channel selection button on an operation panel (not shown). Select the channel you want to play. In this case, a list of the channel contents (piano accompaniment, guitar accompaniment, percussion ...) of the received accompaniment performance data is displayed together with the channel number on the display section of the panel.

The channel selection information is read by the controller 3, and the controller 3 gives the performance information processing apparatus 1 an instruction not to send the performance data of the channel to the tone generator circuit 2. For example, the note-on and note-off performance data having the selected channel number is rewritten by the data suppression unit 1d (data conversion unit 1c) as invalid data as the pronunciation information. This prevents the performance sound of the performance participant from competing with the accompaniment sound of the corresponding channel of the received accompaniment performance. The data suppressing unit 1d may not simply send the performance data of the channel of the selected number to the tone generator circuit 2.

Next, the performance participant selects his or her performance means with the selection button on the panel. MIDI as a musical instrument such as a keyboard instrument capable of transmitting MIDI performance data
It is possible to select a specification musical instrument or a natural musical instrument capable of transmitting an electric audio signal such as an electric guitar, an electric bass, an acoustic piano with a mute function, or the like.

When a MIDI instrument such as a MIDI keyboard is selected, the selected instrument information is read by the controller 3 and a control signal is sent to the input selection switch 4 so as to select the MIDI input. Selected MIDI
The input is supplied to the performance information processing apparatus 1 via the MIDI interface 5, and MIDI performance data (pitch number,
Note-on and note-off data including key depression velocity information) is converted into the performance data of the selected channel described above. That is, the data converter 1c converts the channel message such as note-on or note-off with the selected channel number, inserts it into the received accompaniment performance data, and sends it to the tone generator circuit 2.

At this time, as the sound source control parameter of the selected channel, the transmission parameter data of the corresponding channel for accompaniment performance received by the telephone line is set in the sound source circuit 2 from the parameter reading unit 1b as it is. Therefore, when the performance participant selects, for example, a piano accompaniment part from the accompaniment performance channel, the performance of the MIDI keyboard performed by the performance participant becomes a tone color of the piano and is sounded in place of the originally transmitted accompaniment performance sound of the piano. Will be. Also, if the transmission control parameter of the selected channel is changed by a control change during the music, the change is reflected in the accompaniment performance of the performance participants.

When the effect parameter is transmitted for each channel, the transmitted effect parameter is set in the tone generator circuit 2, so that it depends on the effect parameter of the corresponding channel transmitted to the accompaniment performance of the piano of the performance participant. A sound effect is added. When an effect parameter having no channel number is transmitted, the same effect sound is added to the performance participant's part and other transmitted accompaniment performance parts.

When a performance participant selects a natural musical instrument such as an electric guitar, a natural musical instrument input is selected by the input selection switch 4, converted into a digital signal by the A / D converter 6, and then supplied to the effector 7. To be done. The effector 7 is a reverb like the effector of the tone generator circuit 2,
This is a type that can simultaneously process multiple effects such as delay, chorus, equalize, and distortion. To the effector 7, the transmitted effect parameter of the channel selected by the performance participant or the transmitted effect parameter common to all channels is sent from the performance information processing apparatus 1 and set. Therefore, the acoustic effect by the transmission effect parameter is added to the guitar performance of the performance participants.

The output of the effector 7 is supplied to the mixer 8 and mixed with the L and R stereo accompaniment performance signals from the tone generator circuit 2. In the accompaniment performance signal supplied from the tone generator circuit 2 to the mixer 8, the part selected by the performance participant as described above, for example, the guitar channel data of the transmitted accompaniment performance data is output from the performance information processing apparatus 1. Since it is suppressed so as not to be performed, the accompaniment sound of the electric guitar by the performance participant and the corresponding guitar part of the reception accompaniment performance in the mixer 8 do not conflict with each other. The output of the mixer 8 is converted into an analog audio signal by the D / A converter 9 and is led to an external amplifier and speaker.
