 While the [MPC Chord Progression Finder](https://github.com/liotier/AkaiMPC/blob/main/AkaiMPCChordProgressionFinder/README.md) helps you identify and recreate chord progressions from existing music, this Generator takes the opposite approach: **it creates new progressions from scratch based on music theory principles**.
 
+## Prefer a Pre-Built Library?
+
+Generating on demand is the point of this tool, but not everyone wants to click through it hundreds of times to build a collection. The entire catalogue - every progression this generator can produce, across every genre, scale, and voicing variant - is built by CI and sitting there as a straight download, no interaction required:
+
+- **`.progression` pack** - every progression, every style variant, as ready-to-load MPC files (key of C - Pad Perform transposes to any key on import)
+- **MIDI pack** - the same catalogue as Standard MIDI Files, already rendered in all twelve keys
