LoopGPT is an AI-powered tool that generates four-bar MIDI loops to inspire musicians without replacing them.It aims to use AI as a tool for enhancing creativity and workflow efficiency in music composition.LoopGPT utilizes large language models for MIDI creation, showcasing high-quality and stylistically nuanced outputs.The interface includes tabs for 'Text-to-MIDI' and 'Prompt Editor' to guide users through the generation process.Users can set parameters like root note, scale type, generative models, and sampling temperature for customization.LoopGPT operates through a modular pipeline with flexible prompts and transparent generation processes.The quality of AI-generated music depends on model size and type, with reasoning models offering more coherent outputs.Prompt engineering strategies like few-shot prompting improve output coherence and musicality.LoopGPT plans to reduce dependence on external APIs by training dedicated MIDI-specific models for improved performance.Future enhancements include adding user controls for MIDI characteristics and integrating open-source models for comparison.
