Loop Recording Playback Control for Multi-Section Music
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording/playback devices, such as loopers, can only record and play back a single section of a musical piece, limiting the ability to create and play back compositions with multiple sections like verse and chorus forms.
Innovation Solution
A recording/playback device that allows users to control recording and playback based on user-defined timepoints, enabling the separation and looping of different musical sections, allowing for the creation and playback of musical pieces with diverse structures by using a determination means to set triggers and a playback control means to manage loop playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-section recording/playback system is used, then the device complexity is low, but the adaptability for multi-section musical compositions is insufficient
Solution Approach 1:
The patent divides the recording/playback system into multiple independent sections (first section with first/second timepoints, second section with third/fourth timepoints). Each section can be independently controlled for recording and playback, enabling multi-section musical compositions while maintaining manageable complexity through modular design
Solution Approach 2:
The system dynamically switches between different operational modes (recording first section, playing back first section, recording second section, playing back second section) based on user instructions. The playback control means enables dynamic transition between sections, allowing flexible adaptation to various musical composition structures
2Adaptability or versatility
If recording and playback are limited to one section, then the ease of operation is high, but the versatility for diverse musical expressions is limited
Solution Approach 1:
The recording/playback device is designed to perform multiple functions: it can record and playback the first section, record and playback the second section, and switch between them. The determination means and playback control means work together to enable the device to adapt to different musical expression needs while maintaining a unified operational interface
Solution Approach 2:
The playback control means acts as an intermediary that manages the complexity of multi-section operations. It receives user instructions and automatically handles the switching between recording and playback modes for different sections, reducing the operational burden on the user while enabling versatile musical expressions

AI summary
The present invention enables diverse expression in a recording/playback device and a recording/playback method that can perform overdubbing. Provided is a recording/playback device and a recording/playback method that stores an inputted voice and plays back the stored voice. The recording/playback device has: a determination means that sets timepoints using sequentially acquired instructions as a trigger; a recording control means that records a voice inputted during the period from a first timepoint to a second timepoint as a first voice, and records a voice inputted during the period from a third timepoint to a fourth timepoint as a second voice; and a playback control means that starts loop playback of the first voice from the second timepoint and stops the loop playback at the third timepoint, and starts loop playback of the second voice from the fourth timepoint.
