Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to an electronic music reproducing apparatus capable of finding an arbitrary portion of a song.

2. Description of the Related Art Conventionally, for example, in a tape recorder type reproducing apparatus, when it is desired to send a tape to an arbitrary part of a song, a fast-forward switch and a reverse switch provided on the main body of the apparatus are operated to operate a tape counter and a sound at the time of fast-forward. Had been cueing. Also, in an electronic music reproducing apparatus represented by MIDI (musical instrument digital interface) data, a fast forward switch and a reverse switch are operated to display the time information and the like added to the performance data. While cueing.

[Problem to be Solved by the Invention] However, there is a problem that the cueing by the conventional tape counter or the time display method does not stop at an expected place because there is no music monitor. Also, with a MIDI-based electronic music playback device, music can be monitored by changing the tempo data of the data normally played and playing faster, but fast-forwarding at a sufficient speed depends on the transfer speed of MIDI and the performance of the photo isolator. There is a problem that reproduction and reverse reproduction cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and provides an electronic music reproducing apparatus that can easily search for a desired position while monitoring music in both forward and reverse directions with a simple operation. It is intended to be.

[Means for Solving the Problems] In order to achieve this object, the electronic music reproducing apparatus of the present invention includes an input unit for inputting information such as selection of a song and reproduction, stop, and fast-forward of the song; A storage means which is capable of storing music performance data and a piece of search data corresponding to the performance data on a one-to-one basis with respect to the performance data, and reads the music performance data from the storage means. A normal playback unit for reading out the search data from the storage unit, a search and playback unit for playing back at a faster speed than the normal playback unit for playing back, and detecting that information such as fast forward is input from the input unit. Then, the search / reproduction means reproduces the data from the performance position of the search data corresponding to the performance position of the performance data being reproduced by the normal reproduction means, and inputs information such as fast forward from the input means. Control means for causing the normal reproduction means to reproduce from the performance position of the performance data corresponding to the performance position of the search data being reproduced by the search / reproduction means when it is detected that the information is no longer input.

[Operation] According to the present invention having the above configuration, the user inputs information such as selection of a tune and reproduction, stop, fast forward, etc. of the tune from the input means. The storage means can store performance data of the music and a part of the performance data, and search data corresponding to the performance data in one-to-one correspondence with the performance timing. When the control means detects that information such as fast forward has been input from the input means, the normal reproduction means reads out from the storage means and reads out the reproduction data corresponding to the play position corresponding to the play position of the play data. The search / playback means is played at a faster speed than the normal playback means,
When it is detected that information such as fast forward is no longer input from the input means, the normal reproduction means reproduces the performance data from the performance position of the performance data corresponding to the performance position of the search data being reproduced by the search / reproduction means.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an electronic music reproducing apparatus using an electronic musical instrument represented by MIDI data.

The performance data is stored in the performance data memory 2 as performance recording means, and the control section 4 as control means reads out the performance data from the performance data memory section 2 sequentially, processes the data, and reproduces the data. It is output as a performance by the reproducing unit 5 and the speaker 6 as means. When the user inputs a command to perform a cueing operation from the input unit 1, the control unit 4 reads out search data from the search memory 3 serving as a search storage unit and performs a search operation described later.

FIG. 2 shows a part of the contents of the performance data. The performance data of one music is an aggregate of bar data. Further, one bar 7 is a collection of music information in step units 9 of the bar 8 for each instrument. During a normal performance, the control unit 4 sequentially reads performance data from the performance data memory 2 in bar units, processes the data, and generates a sound. One-step performance data includes note information such as scale, length, step time, and gate time, as well as system control information such as tempo change, sound source parameter change, and pitch change.

FIG. 3 shows a part of the contents of the search data. The difference from the performance data is that the musical instrument is limited to one, for example, only the main accompaniment musical instrument, and the performance data in one step is limited to data of only the scale and the pitch, and other note information and That is, it does not have system control information as data.
Regarding the measure number and step number indicating the performance location,
Performance data and search data have a one-to-one correspondence.

Next, the operation of the electronic music reproducing apparatus according to the present embodiment will be described with reference to FIGS.

When the user wants to find the beginning of a song at an arbitrary position, he or she turns on the fast forward switch or the reverse switch (hereinafter referred to as the beginning switch) of the input unit 1 (step 1, hereinafter S1).
Called. Other steps are the same). Then, the control unit 4 reads the data of the search memory unit 3 storing the search data according to the measure number and the step number indicating the current performance position, instead of the performance data memory 2 (S2). After processing the data (S3), the performance is performed in the same manner as the performance data (S4). In this case, the playback speed uses a preset tempo faster than that during normal performance. S2 to S4 are repeated until the cue switch is turned off (S5). When the cueing switch is turned off, the next measure number and step number played by the cueing operation are set (S6), and the sequence returns to the normal performance sequence.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the gist of the invention.

For example, search data may be automatically generated from performance data by conversion software.

[Effects of the Invention] According to the present invention, it is possible to easily search for a desired position while monitoring music in both the forward and reverse directions with a simple operation, and furthermore, search data is composed of a part of performance data. Therefore, the search data can be created more easily than the performance data, and it is possible to provide an electronic music reproducing apparatus that does not need to separately create the search data separately from the performance data.
