Hydra II

Hydra II comes from Rightsify, a music licensing company led by CEO Alex Bestall, and is trained entirely on Rightsify's own catalog of more than a million songs, including audio, MIDI, chord and sheet-music data. That ownership is the selling point: outputs are copyright-free and cleared for commercial use. It takes prompts in more than 50 languages, draws on 800-plus instruments, and includes editing tools for tempo, key, stems and mastering. Rightsify also licenses its catalog as training datasets to other AI companies, which makes it a player on both sides of the data question.
