This programme is for Apple-silicon Mac producers, sound designers, and composers with substantial local sample libraries. If your setup fits, you get an invitation and try the full app on your own library for 14 days.
To keep it, you pay €59 once, which covers private beta access, manual beta updates, direct support from me, and the eventual v1 release.
These first builds support macOS 14+. Applying and trying don't commit you to buy.
