Documentation

From the project README

A local process extension by DrHepa. One Text to Music node uses the real ACE-Step 1.5 Turbo inference API to produce instrumental music or songs from a description and optional lyrics. This is music generation, not a speech TTS or voice-cloning adapter.

setup.py prepares an isolated runtime and downloads the pinned model files to Modly's persistent models directory. processor.py only reads local weights; it never downloads them. This follows the current process contract, not the separate weight-download UI used by model extensions.

Target: upstream Modly 0.4.2, audited at 1476fd0. See VALIDATION.md for the exact evidence and untested targets.

Worlds We Make — a two-minute epic synth-pop song about creating worlds with Modly, with original English lyrics and a requested female lead vocal.
