Create pattern data. The musical tone data input process is the same as the corresponding process in creating musical tone pattern data corresponding to the synth track, except that an operation for designating a tone color for each musical tone data is added. Therefore, switch 1₁~ 1₁₆Of these, the one pressed is configured to blink.
[0040]
The method for inputting musical sound data in the real-time input mode (b) is assigned to the performance instruction operator 1 by operating the performance instruction operator 1 in real time so as to actually play a musical instrument. An input method for creating musical tone pattern data while designating each musical tone data. Even when the real-time input mode is selected, the musical tone pattern data is created for each automatic performance track as in the step input mode.
[0041]
When creating musical tone pattern data corresponding to a synth track in the real-time input mode, the user first shifts to the real-time input mode. In the present embodiment, since the default state is the real-time input mode, it is not usually necessary to perform any operation. However, when the step input mode is currently selected, the event select switch 2e is pressed to perform the step. It is necessary to shift from the input mode to the default real-time input mode.
[0042]
Next, a synth track is selected by pressing the synth track selection switch 2a, and a desired tone color is selected by operating the dial operator 2h for setting a tone color. Then, recording is started by pressing the start switch 2k, and musical tone data of the pitch assigned to the operator is input by pressing the performance instruction operator 1 at a desired timing.

In the present embodiment, the performance instruction operator 1 is a switch 1 as described above.₁~ 1₁₆These switches 1₁~ 1₁₆Switch 1₂, 1_Three, 1_Five~ 1₇Each switch of the switch is like a black key on the keyboard, and switch 1₉~ 1₁₆As a white key on the keyboard. That is, all 16 switches 1₁~ 1₁₆Among them, a pseudo keyboard is formed by using a total of 13 switches including 5 switches corresponding to black keys and 8 switches corresponding to white keys. When creating musical tone pattern data corresponding to a synth track, each key (switch) of this pseudo keyboard is assigned a musical tone of all pitches within one octave, as in the actual keyboard. By pressing a favorite switch at a desired timing, it is possible to input musical tone data of a corresponding pitch at that timing. Note that a switch that is not associated with a key on the keyboard, that is, switch 1₁, 1_Four, 1₈When the real-time input mode is selected, no musical tone is assigned, and no musical tone data can be input even if the user operates the switch.
[0044]
When creating musical tone pattern data corresponding to a rhythm track in the real-time input mode, the user first shifts to the real-time input mode in the same manner as when creating musical tone pattern data corresponding to a synthesizer track.
[0045]
Next, a desired track is selected from the three rhythm tracks by pressing the rhythm track selection switch 2b a predetermined number of times. Then, the tone color of the musical tone data to be input is determined using the pseudo keyboard. As described above, the rhythm track is a track for automatically playing musical tone pattern data of the tone of a rhythm instrument, that is, the tone of a drum instrument or a bass instrument. Select the one you like from
[0046]
When the tone of a drum instrument is selected, the drum instrument usually determines the tone, not to mention the tone, in many cases the pitch of the instrument is determined. Assigns the tone of one instrument (in the case of a drum set, each instrument such as bass drum, snare drum, hi-hat cymbal, etc.). Note that table data in which each key of the pseudo keyboard and the musical instrument to be assigned to each key are associated with each key according to the type of the instrument is stored in, for example, the ROM 6, and the user determines the type of the instrument. In addition, the table data corresponding to the type of the instrument may be read, and the tone color of the instrument may be assigned to each key of the pseudo keyboard based on the table data. In addition, when assigning to the performance instruction operator 1 a musical tone that is generated for each musical instrument, such as a drum-type instrument, the performance instruction operator 1 imitates a keyboard. Since there is no need to perform all the operations, all the switches 1 constituting the performance instruction operator 1₁~ 1₁₆May be used or all switches 1₁~ 1₁₆If there are no timbres to be assigned, the necessary number of switches may be selected. Even in such a case, it is not necessary to assign a timbre by skipping adjacent switches in consideration of the black key.
[0047]
When the tone of the bass instrument is selected, each tone produced by the bass instrument has its own pitch. In this case, when creating tone pattern data corresponding to the above synth track In this way, it is only necessary to assign musical tones of full pitch within one octave to each key of the pseudo keyboard.
[0048]
Then, recording is started by pressing the start switch 2k, and musical tone data assigned to the operator is input by pressing the performance instruction operator 1 at a desired timing.
[0049]

Since the musical tone pattern data to be edited is selected when the edit mode is entered, the track to be edited is first selected by pressing the synth track selection switch 2a or the rhythm track selection switch 2b.
[0051]
Next, each tone data of the tone pattern data corresponding to the selected track is edited by the same method as described in the step input mode. That is, first, switch 1₁~ 1₁₆By pressing one of the switches, the musical sound data at the position to be edited is designated. Note that each tone data constituting the tone pattern data is all switches 1₁~ 1₁₆It does not always exist at a position corresponding to the switch, and may exist only at a position corresponding to a part of the switches. Therefore, it is preferable to turn on the built-in LED for the switch that indicates the position where the musical sound exists. Next, since the current setting status (setting values of various parameters) of the musical tone data corresponding to the pressed switch is displayed on the LCD 9a, the dial operator 2h is operated to suit the user's preference. To correct.
[0052]
Similarly, editing is performed on the tone data of other positions and the tone data of the tone pattern data corresponding to other tracks.
[0053]
[Automatic performance function]
As described above, the automatic performance function automatically reads out newly created musical tone pattern data, musical tone pattern data after editing, or musical tone pattern data that has been created in advance and has not been subjected to any processing in a loop to automatically perform the performance. The automatic performance function is activated when the automatic performance mode is selected. Since this automatic performance mode is the default mode in the present embodiment, there is no need to perform mode transition again when mode transition is not performed, and when a mode other than the automatic performance mode is selected. Only when a predetermined operation is performed, for example, by pressing the stop switch 2j, the automatic performance mode is entered.
[0054]
