Problems solved by technology

[0008] However, it is difficult to operate the recording switch so that the time regarded as 1 bar is exactly consistent with the standard 1-bar time determined by tempo and tempo
[0009] As above, in the conventional looper, there is a problem that high-quality loop data cannot be created with a stable rhythm.

Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0024] A. Structure

[0025] figure 1 It is a block diagram showing the overall configuration of an electronic musical instrument 100 including a recording / playback device (looper function) according to an embodiment of the present invention. In the figure, the keyboard 10 generates performance information such as key-on / key-off signals corresponding to performance operations (key press-and-release operations), key numbers, and velocity. The switch unit 11 has various operation switches arranged on the panel of the device, and generates a switch event corresponding to the type of the operated switch. As the operation switch related to the gist of the present invention, in addition to the operation switch for setting the "speed (BPM value)", "tempo" and "number of expanded measures (described later)" which are the operation parameters of the initial recording process d...

Abstract

A recording and playback device (100) according to the present invention stores in a memory section (14) sound data for an amount of time corresponding to a beat which is acquired from an external source, and creates loop sound data in bar units by connecting a plurality of stored sound data. Then, the recording and playback device performs an operation to overlap newly acquired sound data onto the loop sound data while the loop sound data is being repeatedly replayed, and store the overlapping sound data in the memory section (14).

Description

[0001] This application claims priority based on Japanese Patent Application No. 2011-187351 for which it applied on August 30, 2011, The whole content is used here. technical field [0002] The present invention relates to a recording and reproducing device and recording and reproducing method for repeatedly reproducing a material recorded for a certain period of time and overdubbing a new material into the repeatedly reproduced material. Background technique [0003] A technique is known in which a material recorded for a certain period of time is repeatedly played back, and a new material is over-recorded on the repeatedly played material (loop audio data). As such a technology, for example, in Japanese Patent Application Laid-Open No. 2011-112679 , an automatic player device is disclosed which repeatedly reproduces a layer in which an event has been recorded in a recording area composed of a plurality of layers (tracks). In this repeated playback, overdubbing is performe...
