Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic musical instrument, and more particularly to a user interface technology for real-time creation of a rhythm pattern.

[Prior Art] Conventionally, in an electronic musical instrument capable of creating a rhythm pattern in real time, there are switches corresponding to several types of rhythm instruments, and by hitting these switches, a rhythm pattern corresponding to the timing of hitting the rhythm is changed. The sound is stored in the pattern memory and the rhythm sound is generated simultaneously. Therefore, for example, when trying out various patterns in a situation where the pattern is not solidified at the idea stage, each time the pattern is memorized, it is necessary to perform a troublesome operation of erasing it and starting over again, The operation burden on the user was heavy.

[Purpose of the Invention] The present invention has been made in view of the circumstances described above, and has as its main object to provide an electronic musical instrument having a rhythm pattern creation function with a good user interface.
More specifically, it is an object of the present invention to provide an environment in which a user can concentrate on practicing a pattern and can easily distinguish whether or not to create a pattern in an input operation.

[Gist of the Invention] In order to achieve the above object, the invention provides a plurality of first key means for inputting a rhythm pattern corresponding to an operation timing and designating a tone of a different musical instrument, and according to the operation. A second key unit for inputting a rhythm pattern, a first storage unit for storing timbre data of a musical instrument, a second storage unit for storing a rhythm pattern, and one of the first key units in a rhythm pattern storage mode. For the key operation, a rhythm sound corresponding to a rhythm pattern corresponding to the key operation is generated by the tone data of the musical instrument designated by the first key means relating to the key operation, and the tone color data of the designated instrument is stored in the first storage means. For the key operation of the second key means, the rhythm sound corresponding to the rhythm pattern corresponding to the key operation is designated and stored in the first storage means. A key point is that the control means causes the tone color data of the musical instrument to sound and the rhythm pattern corresponding to the key operation and the tone color data of the designated musical instrument stored in the first storage means to be stored in the second storage means.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an external view of an electronic musical instrument according to the present embodiment.
The keys include a keyboard 1k in the front, various control switches 1c in the rear, and speakers 13 on the left and right. Control switch
Of 1c, 1M specifies the REC mode of the rhythm pattern with the rhythm REC key. 1R is a start / stop switch for instructing start and stop of accompaniment. 1W is a write key for giving the timing of a pattern when creating a rhythm pattern. The low temperature range of the keyboard 1k is the rhythm pattern REC
In the mode, it functions as an input instrument designation key 1P. For example, when a bass drum key (BD) is pressed, a bass drum sound is designated.

As will be described later, this embodiment is used in a state where the rhythm mode REC mode is selected by the rhythm REC key 1M. In this mode, if the accompaniment is running with the start / stop switch 1R, pressing the write switch 1W creates a rhythm instrument for which the rhythm pattern is selected, and also produces sound. The rhythm instrument to be selected is the one designated by the input instrument designation key 1P pressed last. On the other hand, when the input instrument designation key 1P is pressed in the rhythm pattern REC mode, the corresponding rhythm instrument is sounded at that timing, and the selection of the rhythm instrument for writing is updated.

FIG. 2 shows the overall configuration of the electronic musical instrument according to the embodiment. Key inputs from the keyboard 1 shown in FIG. 1 are read by the CPU 2, and the CPU 2 performs processing according to the program stored in the program memory 3 to control various components.
Reference numeral 4 denotes an accompaniment pattern memory for storing an accompaniment pattern of a rhythm, a bass, and a chord. Upon reading, a corresponding sound source is activated in accordance with the pattern data. As sound sources, a rhythm sound source 5, a melody, a bass, a chord sound source 6, and a sampling sound source 7 are prepared. The acquisition path of the sample sound to the sampling sound source 7 is the microphone 8, the speaker 9, and the A / D converter 10. The tone signals generated from the sound sources 5, 6, and 7 are emitted outside through the D / A converter 11, the amplifier 12, and the speaker 13.

FIG. 3 shows a configuration of a main part of the embodiment. In the figure, all elements other than the rhythm pattern memory 4S are functional elements of the CPU 2 in FIG.

The clock is sent to the address counter 22 by the clock 21, and in response to this, the address counter 22 increments the internal count data. One of the incremented count data is used as an address of the rhythm pattern memory 4S as shown. The clock 21 supplies a read timing signal to the pattern read unit 23. In response to this, the pattern read unit 23 reads the pattern data by supplying the read signal to the rhythm pattern memory 4S, and passes it to the output control unit 24.

The rhythm pattern memory 4S is a pattern memory area selected for creating a rhythm pattern, and nothing is initially written. Therefore, the pattern reading unit 23 does not activate the output control unit 24 while the data read from the rhythm pattern memory 4S is not the pattern data,
Therefore, no rhythm sound is output.

In the key scan 25, the key input processing of the input instrument designation key 1P and the write key 1W is separately performed for the purpose of the embodiment. When the key scan 25 detects a key press of the input instrument designation key 1P, it outputs a key press signal and key information (key code). Key press signal is selected rhythm tone flag section 26
Is updated with the key information, and is passed to the output control unit 24 together with the updated flag content. For this reason, the output control unit 24 executes the sound generation processing of the rhythm sound source indicated by the selected rhythm tone color flag unit 26. Meanwhile, key scan
When the key 25 detects the key depression of the write key 1W, the key depression signal and the contents of the selected rhythm tone color flag part 26 at that time are passed to the output control part 24 for sounding, and the key depression signal is outputted. The content of the selected tone color flag section 26 is input to the rhythm pattern memory 4S as pattern data as a write signal. As a result, the pattern data is recorded in the rhythm pattern memory 4S at the address indicated by the address counter 22 at that time.

As described above, in the present embodiment, only the pronunciation plus storage and the pronunciation are divided depending on whether the write key 1W or the input instrument designation key 1P is operated.

Although not explicitly shown in FIG. 3, the write signal to the rhythm pattern memory 4S by the write key 1W operation is enabled only when the support pattern is read by reading the pattern from the support or accompaniment pattern memory. can do.

The flowchart shown in FIG. 4 implements this aspect.
9 shows a processing program of the CPU2. First, the user presses the rhythm pattern REC switch 1M to establish the rhythm pattern REC mode (S
8). In this mode, when the write key 1W or the input instrument designation key 1P is pressed, the process proceeds to S2, S6, S10, S11, and then
The rhythm pattern REC process of S12 is executed.

As can be seen from the detailed flow of the rhythm pattern REC process S12, when the write key 1W is pressed (NO in S12-0), when the accompaniment such as rhythm is running (YES in S12-2), the rhythm pattern Writing to the memory 4S is performed. here,
The write address of the rhythm pattern memory 4S is switched depending on whether the key depression timing of the write key 1W is later or earlier than the step timing of the rhythm address counter (S12-5, S12-6, S12-7). That is, when the write key 1W is pressed shortly before the rhythm address counter advances, the value of the current rhythm address counter plus 1 is added, and when the key is pressed immediately after the advance, the rhythm address counter is used. Is set as the write address. In any case, data is written to the write address using the contents of the tone color flag 26 at that time (S12-9).

If the write key 1W is depressed later than the step timing of the rhythm address counter, a delay flag is set for immediate sound generation (S12-8), converted to a rhythm sound output data format, and converted to a rhythm sound output data format. Is set and sound is generated (S12-10, S12-3, S12-4).

(A) When the input instrument designation key 1P is pressed, or (b) when the write key 1W is pressed without rhythm or other accompaniment support, writing is not performed and only immediate sound generation is performed. (S12-3) and (S12-4). In particular, in the case of (a), the timbre flag 26
Is updated (S12-1).

The output of the rhythm and other accompaniment support and the output of the pattern created in the rhythm pattern memory 4S are performed in the rhythm accompaniment sound processing S4 (S4-1 to S4-1).
0).

[Effects of the Invention] As described in detail above, in the present invention, in the rhythm pattern storage mode, when a rhythm pattern of about one bar or several bars is memorized in small increments,
First, after operating the first key means to produce the rhythm sound of the rhythm pattern with the designated musical instrument, if the rhythm sound is a favorite rhythm sound, the second key means is changed to the same as the first key means. Operate as follows. As a result, when a rhythm pattern of one measure or several measures is memorized in small steps, it is not necessary to shift to the reproduction mode each time, and recording can be performed by a simple operation.
