DETAILED DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timbre editor (timbre editor) for performing timbre editing (timbre editing) of a timbre composed of a plurality of tones.

[0002]

2. Description of the Related Art A tone assigned to an arbitrary part of a sound source of an electronic musical instrument (a tone unit usually called a patch used during an actual performance) is composed of one tone (phoneme piece as a basic tone unit). Not only that, it is generally created by combining a plurality of tones. Normally, each of these tones has parameters such as a filter cutoff frequency, resonance, and an amplitude envelope, and the tone can be edited by changing these parameters for each tone. . In this editing, there are cases where it is desired to change a plurality of tones constituting a tone at the same time. Here, each parameter is changed, for example, by operating a volume or a switch group on a panel assigned to each parameter.

A conventional timbre editing device for performing timbre editing has a plurality of tone on / off buttons and a plurality of tone selection buttons provided corresponding to a plurality of tones constituting a timbre. Is used to turn on / off each tone and set a tone to be edited. Here, the tone on / off button is a switch for turning on / off whether or not each tone constituting a tone is to be sounded on the panel. The tone selection button is a switch for setting which of the plurality of tones constituting the timbre is used as an editing means for the volume or switch group for performing the timbre editing. When all the tones are selected at once, the editing of the timbre by the editing means is performed simultaneously for all the tones constituting the timbre.

It is changed in accordance with the operation of the operated tone color parameter changing operators 12 to 15 (step S54). This allows
The timbre editing of the rhythm part R currently selected in the part mode is performed according to the operation contents of the timbre parameter changing operators 12 to 15, and the operators 1 to 8 of the eight rhythm sounds constituting the rhythm part R are changed. 8 is performed only for the one rhythm sound selected most recently. Finally, L
When the setting content of the FO waveform is changed, the display 31 of the LFO waveform is turned on / off according to the setting content.

In implementing the present invention, various modifications are possible. In the above-described embodiment, the controls 1 to 8 to which the tone tone editing function is assigned in the tone mode are assigned the part selection function in a mode other than the tone mode (that is, the part mode). The present invention is not limited to this. For example, a rhythm mute function may be assigned to the operators 1 to 8 instead of the part selection function. Hereinafter, this embodiment will be described.

Here, the rhythm mute function controls on / off of sound generation of each rhythm sound by the automatic performance data. For a rhythm sound which is not muted, the automatic performance data is sent to the sound source 45. Pronounced,
With regard to the rhythm sound in the muted state, the automatic performance data is not sent to the sound source 45, and the sound is not generated. It should be noted that regardless of the state of the rhythm mute, sound is generated by playing the keyboard. This rhythm mute function makes it possible to perform an automatic performance only for an arbitrary rhythm sound.

In this embodiment, the rhythm mute mode operator 1 is used instead of the part mode operator 9 of the above-described embodiment.
6 is provided, and either the rhythm mute mode or the tone mode is selected by the mode selection operator. With respect to the part mode function, another operator (not shown) for performing the function is provided.

In the rhythm mute mode, the rhythm mute function is assigned to the operators 1 to 8, and in the tone mode, the same functions as those in the tone mode in the above-described embodiment are assigned to the operators 1 to 8. In the rhythm mute mode, each of the operators 1 to 8 is associated with each of the eight rhythm sounds, and the mute state of the corresponding rhythm sound is switched each time the operators 1 to 8 are operated. Depending on the mute state of each rhythm sound set in this way, regardless of the mode (that is, whether the rhythm mute mode or the tone mode), the sound on / off of the rhythm sound is turned on / off.
Off is controlled.

The ROM 42 stores rhythm sound presence / absence data indicating whether or not there is rhythm performance data for each rhythm sound corresponding to each automatic performance data. I have. For example, when rhythm performance data for playing a bass drum is included in the automatic performance data, rhythm sound presence / absence data to that effect is stored.

The RAM 43 is provided with a rhythm sound data presence flag and a rhythm mute flag for each rhythm sound. The rhythm sound data presence / absence flag is used to copy the contents of the rhythm sound presence / absence data of the automatic performance data when the automatic performance data is newly selected. Indicates the presence or absence of rhythm performance data. The rhythm mute flag indicates a mute state of each rhythm. In the rhythm mute mode, each time one of the operators 1 to 8 corresponding to the rhythm sound in which the rhythm performance data exists is operated. The contents of the flag are inverted.

In the rhythm mute mode, the display contents of one or more of the indicators (one or more of the displays 21 to 28) of the corresponding operator are controlled according to the setting contents of the rhythm mute flag and the rhythm sound data presence / absence flag. You. That is, the indicator is turned on for rhythm sounds that have rhythm performance data and are not in the rhythm mute state, and are blinked for rhythm sounds that have rhythm performance data but are set to rhythm mute. For a rhythm sound having no rhythm performance data, its display is turned off. Therefore, for the rhythm part of the automatic performance data, the presence / absence of the rhythm performance data of each rhythm sound that sounds the rhythm part can be seen at a glance for each rhythm sound, and also when the mute state of the rhythm sound is set.
It is also possible to prevent a useless operation such as muting a rhythm sound having no rhythm performance data to play the rhythm.

The operation of this embodiment will be described below with reference to the flowchart. [Flow of Display Lighting Control Process by Mode] FIG. 9 is a flowchart of display transfer control process by mode. When a mode selection operator (tone mode operator 10 or rhythm mute mode operator 16) is pressed, the processing of this flow is performed. By this processing, the mode is switched, and the lighting / flashing / extinguishing control of each of the indicators 21 to 28 corresponding to the operators 1 to 8 is performed according to the new mode. In particular, when the rhythm mute mode is set, whether or not the currently selected automatic performance data includes rhythm performance data for sounding each rhythm sound can be seen at a glance by the lighting / flashing states of the indicators 21 to 28. Is displayed.

First, one of the rhythm mute mode and the tone mode is set according to the operated mode selection operator 10 or 16 (step S61).
If the tone mode is set, the process in the tone mode in the flow shown in FIG. 3 (step S4)
To S9).

When the rhythm sound mute mode is set (step S61), the corresponding display is turned on, blinked, and turned off in accordance with the rhythm mute flag and the rhythm sound data presence / absence flag (step S63). .
That is, when the rhythm mute flag is not set and the rhythm sound data presence / absence flag is set, the light is turned on.
When both the rhythm mute flag and the rhythm sound data presence / absence flag are on, the state is turned on and off when the rhythm sound data presence / absence flag is not on. As a result, the indicator is turned on for rhythm sounds having rhythm performance data but not in the rhythm mute state, and the indicators are blinking for rhythm sounds having rhythm performance data but set to the rhythm mute state. For a rhythm sound having no rhythm performance data, its display is turned off.

[Rhythm Mute Operation Processing Flow] FIG.
Shows a flowchart of the rhythm mute operation process. In the rhythm mute mode, one of the operators 1 to 8 for which the rhythm sound data presence / absence flag is set (that is, the operator whose rhythm performance data of the corresponding rhythm sound exists and whose corresponding display is lit or blinking). ) Is pressed, the rhythm mute operation processing flow is performed. By this processing, the rhythm mute state is switched for the rhythm sound corresponding to the newly pressed operator, and the corresponding display is turned on and blinked according to the newly set rhythm mute state.

That is, the content of the rhythm mute flag of the rhythm sound corresponding to the operated one of the operators 1 to 8 is inverted (step S71), and the content is set according to the content of the newly set rhythm mute flag. If the rhythm mute flag is not set, the corresponding indicator is turned on. If the rhythm mute flag is set, the corresponding indicator is set to blink (step S72).

In the above-described performance data selection processing, the rhythm sound data presence / absence data of the selected automatic performance data is copied to the rhythm sound data presence / absence flag, and all rhythm mute flags are muted for all rhythm sounds. It is cleared to the state that has not been done. In the performance data reading process (not shown), when the rhythm performance data of the rhythm sound is read from the automatic performance data,
When the rhythm mute flag corresponding to the rhythm sound is not set, the rhythm performance data is supplied to the sound source 45. When the rhythm mute flag is set, the rhythm performance data is not supplied to the sound source 45. Is processed.

In this embodiment, rhythm sound presence / absence data indicating whether or not there is rhythm performance data for each rhythm sound in the ROM 42 corresponding to each automatic performance change data is stored in the ROM 42. Although it is assumed to be stored in advance, there is no rhythm performance data that retrieves the automatic performance data and sounds each rhythm sound at a predetermined timing, for example, when automatic performance data is selected. May be determined.

If the automatic performance data can be arbitrarily created by the user, there is rhythm performance data for searching the contents of the created automatic performance data and generating each rhythm sound when the automatic performance data is created. It may be determined whether or not the rhythm sound is present, and the rhythm sound presence / absence data may be stored in association with the automatic performance data.

Further, in this embodiment, whether or not there is rhythm performance data for sounding the rhythm sound in the automatic performance data for each rhythm sound is displayed. It may be displayed whether or not the automatic performance data includes the part performance data for sounding the musical tone of the performance part.
