You're all set

The Pocket Lite · Rubato Audio

The Pocket Lite is installed in your User Library. To start using it:

1. Open Ableton Live (or restart it if it was already running — Live caches its browser at launch).
2. In the browser sidebar, click Library → Max for Live, then filter to MIDI Effect.
3. Drag The Pocket Lite onto a MIDI track that has a clip you want to quantize. The header should read THE POCKET LITE · Rubato Audio.
4. Click the clip to focus it — its notes appear in The Pocket Lite's piano roll, ready to quantize.

The full workflow guide (the four dials, AUDITION vs COMMIT, DRUMS-mode per-lane overrides) is in the README.md inside the install folder.
