The mode selector switch 4 is used to switch and set various processing procedures by the sampler and an operation target to be assigned to the pedal switch 3. In this embodiment, "recording-forward reproduction mode", "recording-forward reproduction mode" -Processing procedures such as "forward / reverse playback mode" and "loop playback mode" can be selected, and the operation target assigned to the pedal switch 3 is volume, tone color, pitch, loop length, and a combination of these. (Ie, a combination of two or more)
Can be set. The pedal switch 3 has a fulcrum approximately in the center, and can be operated by increasing the amount of operation when stepping on the toe side of the operator's foot, and can be decreased by pressing down on the heel side. Is something that can be done. In the following description, the direction in which the pedal switch 3 is depressed toward the toe side is referred to as the "depression direction", and the direction in which the pedal switch 3 is depressed toward the heel side is referred to as the "return direction".

On the input side of the DSP 2, an analog musical tone signal given by an electronic musical instrument is digitized.
An A / D converter 14 is installed, and a D / A converter 15 that converts a digital signal into an analog signal is installed on the output side of the DSP 2. Further, an LED 16 indicating a recording state and a recording standby state is mounted.

Next, the operation of this embodiment configured as described above will be described. 2 to 4 are flowcharts showing a processing procedure when the "recording-forward reproduction" mode is set by the mode changeover switch 4. Figure 2
Is a flowchart showing an operation procedure for setting a recording standby state as an operation before recording a musical tone signal by the sampler. When the pedal switch 3 is depressed, the recording standby state is set, and the LED 16 blinks to start recording standby. Notify the operator of the state (step ST
1 to ST3).

FIG. 3 is a flow chart showing the operation procedure of the recording process. To describe the procedure of the recording operation with reference to FIG. 3, a musical tone signal is input from the electronic musical instrument, and the input signal becomes a certain value or more ( YE in step ST11
S) and when the recording standby state is set (YES in step ST12), under the control of the recording control unit 6, an operation of writing the inputted musical tone data into the memory 1, that is, recording is started. (Step ST13). That is, as shown in FIG. 9A, the pointer moves from the start address in the memory 1 toward the end address, and the inputted musical tone signals are sequentially written in the memory 1.

At the same time, the recording standby state is avoided (step ST14), and when recording is in progress (YES in step ST15), the LED 16 is turned on to notify the operator that recording is currently in progress. Then, (step ST16), when the storage area in the memory 1 is saturated (when the pointer shown in FIG. 9A reaches the end address), or when the pedal switch 3 is depressed again, a recording end signal is given. If it is input, the recording is stopped (NO in step ST15), and the LED 16 is turned off. In this way, recording in the memory 1 is performed.

FIG. 4 is a flow chart showing a procedure for reproducing the musical tone data recorded by the procedure shown in FIG. When the musical tone signal recorded in the memory 1 is reproduced, the recorded musical tone signal can be reproduced by operating the pedal switch 3. In the present embodiment, the central portion of the pedal switch 3 that can continuously change the operation amount is set to the reference position, and when the pedal switch 3 is operated from the lower side to the upper side with respect to the reference position ( That is, it is set so as to detect the start of reproduction by returning the pedal switch 3 from the depressed state to the original state. That is,
When an operation for operating the pedal switch 3 from the lower side to the upper side is performed, this operation is detected by the pedal operation recognition unit 13 shown in FIG. 1, and is recorded in the memory 1 under the control of the reproduction control unit 7. The musical tone signal will be reproduced. By this operation, the pointer moves from the start address to the end address as shown in FIG.
Plays the tone signal recorded inside. At this time, it is possible to reproduce the portion where the recording is completed even if the recording is continued.

That is, the processing procedure of the "recording-forward reproduction" mode shown in FIGS.
First, when the operator depresses the pedal switch 3 to the end to enter the recording standby state, the LED 16 blinks, so that the operator can recognize that the recording standby state is currently set. When an electronic musical instrument such as a guitar is played, recording is started when the musical tone signal obtained from the electronic musical instrument reaches a certain level. When the storage area in the memory 1 is saturated (when the pointer shown in FIG. 9A reaches the end address), or when a recording stop command is input by depressing the pedal switch 3 again The recording is stopped, and at this time, when the pedal switch 3 is passed from the lower side to the upper side of the reference position, this operation is detected and the recorded musical tone signal is reproduced and sounded from the speaker. become. Further, when the recording completed portion is reproduced before the recording is completely finished, the pedal switch 3 is not depressed to stop the recording before the storage area in the memory 1 is saturated. 3 may be moved from the lower side to the upper side of the reference position.

Therefore, the musical tone signal obtained from the electronic musical instrument can be recorded by the simple operation of the pedal switch 3 and the recorded musical tone signal can be reproduced in real time. It becomes possible to widen the width.

FIG. 5 shows that when the "recording-forward / reverse playback" mode is set by the mode selector switch 4,
6 is a flowchart showing a processing procedure, in which, in this mode, the recorded musical tone signal is reproduced in a forward direction or a reverse direction by each operation of depressing the pedal switch 3 and returning the depressed pedal switch 3 to the original state. Is something that can be done. That is, when the pedal switch 3 is moved from the lower side to the upper side to pass the reference position of the central portion in the state where the musical tone signal is recorded in the memory 1 by the procedure of the flowchart shown in FIG. (YES in step ST31), the tone signal recorded in the memory 1 is reproduced in the forward direction (step ST32), and when the pedal switch is moved from the upper side to the lower side to pass the reference position (in step ST33). YES), the recorded musical tone signal is reproduced in the reverse direction (step ST34). Here, the forward reproduction means reproduction in the same order as the recorded order (normal reproduction), and the reverse reproduction means FIG. 9 (c).
As shown in FIG. 2, the tone signals recorded in the memory 1 are reproduced from the end address side toward the start address side, that is, in the order opposite to the order in which they are recorded. It is mainly used to pronounce. According to such an operation, the operator can easily switch between the forward reproduction and the reverse reproduction depending on whether the pedal switch 3 is operated in the depressing direction or the pedal switch 3 is operated in the returning direction. It becomes possible to obtain a wider reproduction sound.

In FIG. 6, the "loop reproduction" mode is selected by the mode selector switch 4, and the pedal switch 3 is selected.
7 is a flowchart showing a processing procedure when a “volume” operation is assigned to the. As shown in the figure, in this operation mode, when an input signal larger than a certain value is given (YES in step ST41) and the recording standby state is set (YES in step ST42), recording is performed. The operation (loop reproduction) of repeatedly reproducing an arbitrary part of the musical tone signal is started (step ST43). This will be described with reference to the schematic diagram shown in FIG. 9D. When the loop point is set in advance, among the tone signals recorded in the memory 1, the signal is recorded between the start address and the loop point. Repeats the existing tone signal.

In this mode, the pedal switch 3
Since the operation of "volume" is assigned to, the reproduction volume is continuously changed under the control of the volume changing unit 11 by operating the pedal switch 3 (step ST45). That is, the output volume increases according to the amount of depression of the pedal switch 3, and the output volume decreases when the amount of depression is small. Then, when the operator minimizes the depression amount of the pedal switch 3, the loop reproduction is stopped (step ST46). Then, according to such an operation mode, the operator reproduces a predetermined portion of the musical tone signal input by the electronic musical instrument in a loop,
In addition, the volume can be operated by operating the pedal switch 3. Since this loop reproduction has real-time properties, it is possible to execute the loop reproduction of the part where the recording is completed even if the recording is not completed.

FIG. 7 is a flowchart showing a processing procedure when the "loop reproduction" mode is selected by the mode changeover switch 4 and the "loop length" operation is assigned to the pedal switch 3. As shown in the figure, in this operation mode, the processing procedure is almost the same as that shown in FIG. 6, and an input signal larger than a fixed value is given (step ST5).
If YES in step 1), and if the recording standby state is set (YES in step ST52), the process of looping the recorded portion is started (step ST53).

In this mode, the pedal switch 3
Since the operation of “loop length” is assigned to, the position of the pointer shown in FIG. 9D can be continuously changed to an arbitrary position by operating the pedal switch 3 (step ST54). That is, if the amount of depression of the pedal switch 3 is increased, the position of the pointer shown in FIG. 9D moves to the right under the control of the pointer position control unit 8 and the loop length is set longer, and conversely, When the depression amount of the pedal switch 3 is reduced, the pointer position is moved leftward and the loop length is set to be short. Then, when the operator minimizes the depression amount of the pedal switch 3 (YES in step ST55), the loop reproduction ends (step ST56). Thus, FIG.
In the process shown in (1), a musical tone signal obtained from an electronic musical instrument is recorded, a desired portion of the recorded musical tone signal is selected and reproduced in a loop, and a position of a pointer for determining a reproduction point is set. Since it can be arbitrarily changed by operating the pedal switch 3, it is possible to perform a wider range of performances. Further, since the loop reproduction sound and the actual performance sound can be output at the same time, it is possible to perform a performance method in which the loop reproduction sound is used as an accompaniment and the main melody is superimposed on the actual performance, for example.

In the examples shown in FIGS. 6 and 7, the recorded musical tone signals are loop-reproduced in the forward direction. However, they are reproduced in the reverse direction or alternately in the forward and reverse directions. It is also possible to switch to and play
It is possible to set such a mode in the mode changeover switch 4. Although illustration is omitted, it is also possible to assign "pitch" or "timbre" to the pedal switch 3, and in this case, by operating the pedal switch 3, the pitch changing unit 9 shown in FIG. Tone change unit 10
Under the control of, the pitch and tone of the reproduced sound can be adjusted arbitrarily.

FIG. 8 is a flow chart showing a processing procedure when the "rhythm reproduction" mode is selected by the mode changeover switch 4. In this processing, the tone signal recorded in the memory 1 is transferred to the sequencer section 12. The pattern is preset to be played. That is, when the level of the input musical tone signal is equal to or higher than the predetermined value and is in the recording standby state (YES in steps ST61 and ST62), the rhythm pattern set in the sequencer unit 12 is the reproduction control unit. 7 is output (step ST63), and the reproduction control section 7 reproduces the recorded musical tone signal by using this rhythm pattern as a trigger (step ST64). When the musical tone signal reproduction process is completed by operating the pedal switch 3 (NO in step ST65), a direct sound,
That is, the sound directly played by the electronic musical instrument is output (step ST66).

This will be described with reference to the schematic diagram shown in FIG. 9E. Now, in the case where rhythms N1 to N5 composed of quarter notes and eighth notes are set in the sequencer section 12, The position of the pointer for setting the reproduction position changes depending on the length of the note. That is, in the case of a quarter note, the pointer moves to the position of the point P2, and in the case of the eighth note, the pointer moves to the position of the point P1, and reproduction is performed in this range. . As a result, it becomes possible to reproduce a musical tone signal in accordance with a preset rhythm pattern and output a rhythmic musical tone.

In this way, in the sampler of this embodiment, the musical tone signal given from the electronic musical instrument can be recorded in the memory 1 and the recorded musical tone signal can be reproduced in real time. It can be used when real-time performance is required.
Furthermore, not only the recorded musical tone signal is reproduced, but the reverse reproduction and the reproduction can be performed by using the pedal switch 3.
You can perform various operations in real time, such as loop playback, changing the loop length during loop playback, adjusting the output volume, changing the output tone, and changing the pitch.
It is possible to perform an extremely versatile operation that meets the needs of the operator.

In the above embodiment, an example in which the DSP 2 (digital signal processor) is used as the arithmetic processing unit has been described, but it is also possible to use a CPU having a high arithmetic speed. Further, although the pedal switch 3 is described as an example of the continuously variable switch in the above embodiment, the present invention is not limited to this, and may be a volume type switch capable of continuously changing the operation amount. Obviously, this is applicable.
