What problem does it solve? Generating complete songs with vocals from text requires either paid services like Suno or complex local model setups. This Skill guides the installation, patching, and execution of HeartMuLa, an open-source music generation model family, so you can produce songs locally from lyrics and tags. ## Core Features & Use Cases - Lyrics-to-Song Generation: Produces full MP3 songs (48kHz stereo) from bracketed lyric structures and comma-separated style tags using 3B/7B models. - Dependency & Patch Guidance: Includes required fixes for transformers 5.x RoPE cache issues and HeartCodec checkpoint loading mismatches. - Hardware Flexibility: Supports lazy loading for 8GB VRAM GPUs, multi-GPU splitting, and CPU fallback. - Use Case: A musician wants an open-source Suno alternative to prototype song ideas locally; this Skill walks through cloning heartlib, downloading checkpoints, and generating a 4-minute track from a lyrics file. ## Quick Start Ask the assistant to install HeartMuLa and generate a song from your lyrics file with tags like 'piano,happy,wedding' using the 3B model with lazy loading enabled.
